- Description
- Opportunity: Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a collaboration to commercialize its method of formulating low-density room temperature vulcanizable polysiloxane rubber compatible with high-resolution injection molding operations. Background: Reactive, neutral cure RTV polysiloxane compositions consists of a base, curative and catalyst, which are combined to yield a mixture that cures to form solid rubber.� To yield a foamed rubber composition on cure, blowing agents or pore-formers are added to the reactive mixture.� Injection molding is ideal for consistent, affordable production of a wide range of high-quality complex parts that can withstand any environment in a variety of industries, especially in the medical and electronics industries.� The properties of silicone, especially liquid silicone rubber, provide a key advantage in injection moldings.� Its shear-thinning property helps silicone to improve its flow into the thin walls of the mold, making it ideal material when the mold has small and intricate details.� However, for closed cavity injection molding operations, blowing agents and sacrificial pore formers are not typically suitable as additives to yield low density foamed rubber composition on cure.� Instead non-reactive pore formers such as microballoons/microspheres are more promising as they can be uniformly distributed and do not adversely react to other components in the composition. Description: LLNL researchers have developed a custom formulated extreme low viscosity reactive silicone resin base modified with a temperature dependent thixotrope along with a modified catalyst package.� The uncatalyzed composition is capable of accepting loadings of polymer microspheres sufficient to produce a cured bulk rubber that has a density as low as 0.3 g/cc, thus compatible with high-resolution injection molding processes.� Depending on the application, the catalyst package can be optimized for a given work, gel and cure time.� The final composition is highly processable post catalysis, allowing for complex features to be properly filled with minimal void entrapment and high fidelity. Advantages/Benefits:� Improved performance of low-density silicone for injection molding Complex geometries can be created Potential Applications:� Electronics capsulation Gap-filling, potting of components Thermal insulation Development Status:� LLNL has filed for patent protection on this invention. Current stage of technology development:� TRL 4 LLNL is seeking industry partners with a demonstrated ability to bring such inventions to the market. Moving critical technology beyond the Laboratory to the commercial world helps our licensees gain a competitive edge in the marketplace. All licensing activities are conducted under policies relating to the strict nondisclosure of company proprietary information.� Please visit the IPO website at https://ipo.llnl.gov/resources for more information on working with LLNL and the industrial partnering and technology transfer process. Note:� THIS IS NOT A PROCUREMENT.� Companies interested in commercializing LLNL's method of formulating low-density room temperature vulcanizable polysiloxane rubber compatible with high-resolution injection molding operations should provide a written statement of interest, which includes the following: 1.�������� Company Name and address. 2.�������� The name, address, and telephone number of a point of contact. 3.� � � � �A description of corporate expertise and/or facilities relevant to commercializing this technology. Written responses should be directed to: Lawrence Livermore National Laboratory Innovation and Partnerships Office P.O. Box 808, L-779 Livermore, CA� 94551-0808 Attention:�� IL-13765 Please provide your written statement within thirty (30) days from the date this announcement is published to ensure consideration of your interest in LLNL's method of formulating low-density room temperature vulcanizable polysiloxane rubber compatible with high-resolution injection molding operations.
