A macro look at the Business of Liquid Silicone from a raw material perspective, as well as a deeper focus of end use markets for LSR and most specifically LIM. Discussing different markets, processes, applications, technologies and the future areas for growth. A special focus on healthcare and medical applications as well as the discussing the global LSR landscape and what the future holds. Lastly, we will include some recent M+A, investments and consolidation in the LSR / Silicone space.
-Summary & Outlook
Since Liquid Silicone Rubber (LSR) was introduced in the late 1970’s it has made its way into many markets and applications as a result of continued enhancements to the processing technology and improvements to end-product quality. More automation needs aligned with higher productivity and the ever increasing performance requirements of the final part have been the driver for this success story.
This presentation will show how this legendary liquid silicone rubber technology can answer “Megatrend” challenges for the industry.
Starting with an introduction of Megatrends, giving some overview of market trends and LSR process, properties and performance the focus will shift to LSR answers for various markets and applications. New developments of LSR technology will be presented extending the current limits. Known and new applications using LSR technology will again highlight the huge potential of this material class.
All will close with a summary and outlook featuring the future of LSR.
Liquid silicone rubber (LSR) has been industrial manufactured in China for over 15 years since 2002. Back then, the annual market demand for LSR was only 3,000T; Applications were limited to few such as PC keyboard and baby nipples. After 15 years of growth, applications have extended to various segment fields as high voltage insulation, automotive, electronics, laser printing, kitchenware, medical apparatus, battery, sportswear, food packaging, military, etc. Up until 2016, the annual LSR demand in Chinese market exceeded 30,000T and has become the fasted growing market in the world. This article will illustrate the current applications in various sectors and most possible new ones in near future.
Over the last decades, the number of electrical systems in cars did significantly increase. While electrical side-windows, airbags or air-condition were perceived as luxury in the 1980s, they are now pretty much accepted standard. At the same time, the goal of increased engine efficiency meeting tighter and tighter emission regulations calls for many secondary systems, sensors and control units. All these E/E devices require electrical connections, resistant against significant temperature changes, working at high and low temperature, survive contact to moisture and a variety of liquids present under the hood.
Silicone elastomers have the necessary set of properties more than any other elastomer material. The dedicated LSR materials for these applications are self-lubricating to enable the assembly of the electrical contacts attached to the cables. Since more than 30 years especially Liquid Silicone Rubber succeeds in this segment based on its excellent fit for high yield mass production application. But still innovation is highly desired for new challenges in ongoing development.
The ongoing focus on CO2 reduction drives downsizing and encapsulation of turbocharged engines. As a consequence the heat increases to levels beyond todays design materials’ capabilities, be it cable insulation, plastic housings or the silicone seals. Another trend is ongoing focus on electrification and autonomous driving, contributing to new needs in longterm-sealing performance.
The paper will explain basics of LSR and selflubricating technology based on an existing broad portfolio of grades. New material advancements in reaction to more demanding requirements in heat and longterm compression set are discussed in this context.
Moldable Optical Silicones are an innovative material sub-set in the Liquid Silicone Rubber (LSR) space. From the start, these materials were designed to meet the unique needs of the optical and lighting markets, while at the same time preserving the properties that enable high volume production in traditional LSR equipment. This presentation will examine the “life cycle” of Moldable Optical Silicone, starting from uncured material, moving through the molding process, and final luminaire assembly.
Synthetic amorphous silica is commonly used reinforcing filler in silicone elastomers when significant improvements in mechanical properties such as tensile strength, elongation at break, and tear resistance are needed. The degree of these improvements depends heavily on the type of silicone polymer used as well as the silica type, its concentration, and surface treatment.
Synthetic silica typically used in silicone manufacturing comes in two forms, fumed and precipitated, owing to its manufacturing method. While both types lead to improvements in mechanical properties, the impact on rheology and optical clarity of the silicone compounds can be drastically different. Fumed silica is often used when high transparency is needed due to its unique cluster-like structure and sub-micron aggregate size; precipitated silica, on the other hand, is not typically used for this function. At the same time, both fumed and precipitated silica are often associated with a significant impact on rheological properties, namely, a strong rise in viscosity, often quite undesirable as it leads to compounds which are more difficult to process.
To address the need for strongly reinforcing fillers with minimal effect on rheology, we developed a new family of hydrophobic silica. In this presentation we will demonstrate how these silica products maintain low viscosity of the silicone elastomers while providing reinforcement at acceptable levels of optical clarity. Test results will be shared to highlight how a combination of structure afforded by the production process and special hydrophobic treatment make these new products a very interesting option for LSR compounds with excellent combination of mechanical, rheological and optical properties.
In this study, the possibilities of foaming liquid silicone rubber (LSR) were investigated. The foam was produced by injection molding with two different fillers. One filler consisted of thermoplastic microspheres, and the other of common liquid water. Different properties were tested using the specimens we produced, e.g. weight savings, hardness, tensile strength, and the compression set compared to unfoamed liquid silicone rubber. It became clear that foaming LSR with the used fillers possesses a high level of potential.
The main focus is to show up the newest technology for LSR metering systems and the description of the technical concept to get a perfect mixture with lowest tolerances and highest process stability of the LSR molding process.
We show the new unique online-degasing Technology SPLITNEX in comparison with piston systems with offline degassing and the big benefit of guaranteed air-free material flow.
The last part of the presentation will show the possibilities to open the process window of LSR Molds with valve gate system in combination with regulation systems. Different concepts are shown and described to cover all shot sizes and cavity numbers.
The production of optical parts and devices e.g. light guides is requiring highly sophisticated tool technology and special processing technology.
Additionally, the demand for improved efficiency and complete documentation is a must in many industries.
The presentation is covering the aspects of innovative tool technology for complex part design in the optical industry. Based on an example for a real part it will be demonstrated how a complete manufacturing cell can look including a fully integrated automation cell with camera inspection, inline quality control and part segregation.
All together, the innovative system is supporting the efforts of companies doing high volume production to improve the efficiency of the manufacturing lines.
For monitoring and controlling the injection molding process in the cavity special sensors, electronics and software are needed which can fulfill the special requirements of the LSR molding process. Applications based on these capabilities are monitoring functions for short shot detection, compression differences, cavity temperatures or balance times. Additional process information can be acquired by measuring the shear rate, shear stress and viscosity directly in the cavity. All this data can be used for quality control purposes. These measurements are also the base for applying smart solutions like automatic balancing of multi cavity cold runner molds or automatic weld line control. Cavity sensors are also the first link in the chain for Smart Factory solutions for molding operations to pick up trends before bad parts are produced.
Presentation topic points:
Different methods of molding Liquid Silicone Rubber makes it easy to provide real feel, accurate prototypes to the customer prior to investing in production tooling. From simple to complex, prototypes can be made in compression molding. In our experience this gives our customers a great advantage and can begin marketing their product prior to large investments. We also have the capability of transforming these prototype tools to lower volume injection molding production tooling while working closely with our trusted mold makers.
Building a complete molding cell from the ground up can be a very large undertaking for even the most experienced custom molder. In this presentation, I will walk you through the entire process of setting up a large scale production ready turnkey molding cell. Starting with the design and prototyping for manufacturability phases all the way through integrating the mold, press, dosing system, and automation together and finally debugging the entire Turnkey Molding Cell. The intent of the presentation is to explain the wide array of options available to molders when putting together a system from the ground up.

This presentation will discuss the LSR molding cell more from the processing knowledge side and less about equipment and tooling technologies and advancements. The presentation breaks down the factors that cause process variations. We will address the important aspects of an LSR molding cell that we try to maintain control of and how each of these factors can contribute to variations in the process that require continuous troubleshooting and parameter changes. We will break this down further by discussing the factors that contribute to short term variations, (hours and days), factors that contribute to intermediate variations, (weeks and month), and factors that contribute to long term variations, (month and years).
Industry 4.0 assumes that mass-produced products will be replaced by mass-customized products that are tailored to the needs of customers. The production environment (production cell) has to adapt to the changed requirements. Especially when using multi-component technology, where LSR is combined with thermoplastics, the production cell consists of much more than just the injection molding machine, the tool and the dosing system. The integration and networking of additional peripherals (dryers, temperature control units, etc.) will be demonstrated using striking examples and the “Wittmann 4.0” solution.
In the early 1990’s the first demand on the combination of a hard component and
LSR (Liquid Silicone Rubber) became necessary. At this time the Automotive Industry was the key driver for this technology. One of the first steps was a system for mechanical bonding as the technology for self-bonding materials was not developed yet. A new molding-technology was born and implemented Ideas in multiple directions: the development of the materials for the hard component and as well the development of the self-bonding LSR material. At the same time the mold technology had to be developed as well in order to fulfill the high demand on these new product-applications.
Nowadays it is not essential that the decision on a Multi-Component part is made just because it is in fashion or because it more or less simply can be done but the focus on these Multi-Component parts should be placed because finally the application/the parts should be strong enough to weather the cycles of business and respond to the market developments.
This presentation provides on overview about the development of the technology with strong emphasis to the mold-technology, the concepts which are available for the production and key points which have to be considered before you decide on this technology based on a short case-study.
The presentation discusses technologies that make silicone parts much “better” = “smarter”. It covers:
The presentation will focus on System solutions and equipment integration into the molding machine to support more compliance with Quality standards, Medical standards and especially Industry 4.0. Unique features for Machines and system requirements will be covered to achieve the integration goal.
Continuous improvements in part design, mold design, and molding processes are essential for maintaining a competitive edge in the ever-expanding LSR Healthcare molding market. By using advanced CAE simulation technologies, design phases can be shortened, molding process can be predicted, and molded parts can be optimized. To achieve these results, the shear sensitive viscosity behavior of LSR materials should be simulated to accurately predict flow behavior and shear-induced heating effects. New fully automatic BLM (Boundary Layer Mesh) technology can create accurate mesh density in required areas. High shear rates in thin film or pin gates and thin wall thicknesses can cause shear-induced heat which influences viscosity, flow behavior, and flow-induced premature scorch and cure effects.
In this paper, several practical examples will demonstrate how advanced mesh technologies can be used to better predict shear-induced material flow behavior and how to optimize vent and over-flow placements. In addition, heat balance inside a high cavitation LSR mold with a narrow cavity spacing requirement will be evaluated. Lastly, optimizing heater placement and heater wattage to avoid cold spot conditions that could influence overall cycle time and part cure behavior will be examined.
Microsystems technology is one of the key technologies of our times. Due to miniaturisation of all components and increase of the amount of cavities – all parts become smaller. The consequences are innovative applications. This trend is cross-sectoral. Electronic components for the latest smartphones, as well as precision parts for high-performance hearing aids or injection catheters for the medical industry are just a few examples. Even the automotive sector is driven towards downsizing – sealings and wire end ferrules reach shot weights far below 1 gramm. On account of these development the classic mechanical engineering had to follow this trend with two principal movements:
Against this backdrop the presentation will show the latest developments for injection molded parts – from dosing system to injection machinery as well as automation concepts. Principal examples serve as explanations and round off the lecture.
Liquid Silicone Rubber and Liquid Injection Molding have played an outsized role in the advancement of Ingress Protection for consumer electronics. This includes audio speakers, smartphones, action cameras, and smart watches where every port, button, speaker vent, and microphone must be protected.
You will find silicone co-molded o-rings around audio jacks, charging ports and sim card trays. For home buttons and side keys you will find a silicone barrier that completely separates the physical part you push from the electrical contacts inside. Speakers use gaskets and pressure vents to protect a fine mesh that keeps water out but allows air to pass.
LSR has allowed consumer electronics producers to innovative and bring new products to market and create new industries where none existed. Case in point, Action Cameras are typically water resistant up to 33ft or 10m without a housing. Without LSR there would be no Action Camera product category.
Future commercial applications and emerging technologies include wearable biosensors and skin-adhered medical devices that are completely dust and water resistant. There is also an opportunity for Cross-Industry Innovation where medical and surgical devices containing electronics can be sterilized via steam autoclave. As LSR and LIM advance so do its potential applications.
Trends in OEM design demand “Speed to Market” via iterative rapid prototyping. EVOLV3D™ is a new material and concept for 3D printing technology that is reshaping the way silicone rubber parts are designed and prototyped. The technology uses heat-curable liquid silicone rubber through a Liquid Additive Manufacturing (LAM) process where functional prototypes can be made in just a few hours. The paper will cover:
The outstanding properties of silicone materials explain their widespread commercial use. However, manufacturing complex 3 dimensional silicone structures remains a significant challenge. Herein, we demonstrate a thiol-ene based photochemistry and inexpensive (<$2) hardware modification that enables high resolution (~50 micron) 3D printing of soft, stretchable silicone devices from common desktop 3D printers. We employed this new capability to print highly resilient soft robotic actuators and patient specific biomedical implants.
True two-shot molding of silicones and plastics still have proven somewhat difficult for users to adapt and implement into medical applications because of processing conditions. Recent technologies have been developed by silicone suppliers that now offer users more flexibility in choice of substrates and adhesion to those substrates. New technologies have been launched into the market in which appropriate biocompatibility testing was primary to their development. Examples of this new technology from Dow Performance Silicones will be highlighted in the presentation.
The medical market has a growing demand for innovative designs that incorporate rigid substrates with a soft, low-durometer overmold. These two-component designs offer improved quality and production efficiencies. Recent advances in polymer chemistry meet the need for devices and housings with a combination of chemical resistance and impact strength.
