Automotive and Transportation applications for Silicone elastomers.
Development of Silicone Rubber Solutions for Transport Applications
Joseph Hallett | Senior Development Chemist of Fenner Precision
Tougher transport regulations, especially relating to passenger safety, coupled with increasing demands from end users have led to more complex requirements for elastomers in transport applications. While many of these requirements have necessitated a move to silicone rubber, a lack of understanding of basic material limitations can lead to unrealistic specifications being set. In this paper the development of a silicone rubber composite designed to meet these requirements will be described. The paper will cover the range of testing required for such applications, the challenges of associated regulations, and the particular benefits silicone based solutions provide.

Multi-shot molding with LSR – from Fiction to Reality
Markus Landl | Head of international business development of SIMTEC (under the umbrella of THE RICO GROUP)
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 fulfil 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.

Virtual Molding for LSR – A Comprehensive approach
Gabriel Geyne | Application Engineer of Sigma Soft
Measuring and evaluating polymer material behavior are the first steps in developing some understanding of how it can/should be processed in a new mold; will it cure faster or slower, should the mold temperature be higher or lower, can the filling time be shorter or longer? This information can be very useful when designing new tools for new products. However, experienced Liquid Injection Molding (LIM) professionals know that it takes more than gate and vent locations to make quality parts at the machine. Heater wattage, location, set point temperature and thermocouple location, mold materials, insulation, cold deck, LSR properties, part geometry gate and runner design...all are combined with process information inside the Virtual Molding machine to capture a true representation the actual part quality. This presentation will address the importance of a comprehensive approach to Virtual Molding.
LSR Mold Fill Evaluation through Comprehensive Multi-point Material Analysis
Tom Jenkins | Executive Director of Business Development of R.D. Abbott
Accurate mold fill analysis of thermoset elastomeric materials is now possible due to advancements in LSR material characterization. Innovative algorithms and testing techniques has led to full multipoint characterization data that now allows for reliable flow analysis of LSR in an Injection Mold. Compared to traditional single point data, the importance of multi-point data is demonstrated to achieve accurate simulation results of the entire injection molding process.

Advancement of LSR in medical and consumer markets
Huiping Zhang | Chemist of Momentive Performance Materials
The pesentation will cover some of recent LSR developments in Momentive Performance Materials Inc.
Self-bonding LSR provides strong adhesion to various thermoplastic substrates; including polycarbonate and polyester, eliminating the need for a separate secondary operation process and enabling direct two-shot or multiple-shot over-molding process. Medical grade self-lubricating LSR generates robust and long-lasting oil bleed performance and is useful in a variety of healthcare applications where assembly is required. UV-curable LSR enables the combination of silicone rubber with temperature sensitive electronics in making wearable devices.
New Material Properties through a Silicone Blend Strategy
Dr. Hab. François Ganachaud | Senior Scientist of French National Centre of Research (CNRS)
Silicone HCRs are rubber materials useful in transportation applications for various parts of engine, rotors, and connectors and so on. To generate silicone elastomers with reinforced properties, a practical solution is to prepare blends of different silicone types. Here I will present two studies that we made on the preparation of new materials with a view to enhance basic properties of silicone (mainly thermal, solvent or vibration resistance). Particularly, the talk will focus on the structure-properties relationship of silicone blends thanks to various characterization techniques (e.g. electronic microscopy, thermal analyses or tensile tests).
Morning Networking Break
AM of Multifunctional Silicone Composites
Dr. Andrew Saab | Enhanced Surveillance Deputy Program Leader for Polymer Materials of Lawrence Livermore National Laboratory
Three-dimensional printing of viscoelastic filled silicone inks can be used to create porous, elastomeric architectures with mechanical properties governed by the ordered arrangement of their sub-millimeter struts. Thermal, chemical, and electrical properties can be tailored through control of composition. Utilizing advances in extrusion based AM approaches, in-situ chemical and in line mixing approaches, both composition and architecture can be tailored to realize spatially graded control over multiple properties simultaneously. We will review some of the structures and compositions our multidisciplinary team have recently developed and experimental and modeling results on the novel structures
Early Engagement… Enabling LSR’s potential
Timothy Rourke | Program Engineering Manager of Dymotek Corporation
In order to fully leverage the significant gains and investments made in the materials, tooling and process development associated with LSR, the industry can engage more effectively earlier in the product development cycle. Major value lies in LSR's ability to integrate conventionally disparate properties and, more importantly to the designer, the resulting functional elements of an overall product design. Too often, a product design is already decomposed into conventional pieces and dispersed for quoting to contract manufacturers before a more integrated solution can be envisioned. We set out to provide tools for design teams to understand the value flow from material properties to design elements, and how they can come together to provide disruptive solutions to our end customers.
Functional Additives for Silicones
Steve Amos | Sr. Product Development Specialist of 3M Company
3M Company makes several plastic additives that are potentially useful for modifying the properties of silicones. These include hollow Glass Bubbles that can reduce the specific gravity of the composite, especially useful for light weighting in transportation applications. A second additive in focus is boron nitride (BN) that is used to impart thermal conductivity while maintaining electrical resistivity. Boron nitride is currently used in silicone rubber pads for thermal interface management (TIM) applications. An overview of the available products and potential applications will be detailed in this presentation.
How Pigments, Fillers and Additives Can Enhance the Properties of Silicones
Dr. Raman Rabindranath | Polychemist, GSDI Specialty Dispersions of PolyOne Corporation
Silicone elastomers represent an outstanding class of elastomers which features rubber-like properties like softness, high elongation as well transparency, chemical inertness and temperature stability, generally attributed to glassy materials. This set of properties renders Silicones one of the most versatile elastomers available. Nevertheless, there is an increasing market demand for functional elastomers. In the compounding of Silicones, functionality is typically achieved through incorporation of pigments, fillers and additives such as flame retardants, heat resistance improver, electrically and thermally conductive fillers, adhesion promoters, self-lubricating oils and many more.
In order to meet today’s requirements, novel approaches towards functional Silicones based on pigments, fillers and additives are presented in this contribution. It is shown how pigments can enhance the heat stability in addition to coloration. In the field of electrically conductive silicones, three approaches based on Single Walled Carbon Nano Tubes (SWCNT), Multi Walled Carbon Nano Tubes (MWCNT) and conductive carbon black are introduced and compared. Furthermore, novel approaches to thermally-conductive elastomers with ferromagnetic properties based on Carbonyl Iron Powder (CIP) which potentially can trigger many new innovative applications are presented. Laser-marking as well as light diffusing options for LED encapsulants are also discussed. Future trends and envisaged R&D goals are outlined in the outlook.
