Liquid Silicone Rubber Injection Molding Jeff LeFan, M.Eng. Saint-Gobain Performance Plastics, 2316 W. Wisconsin Street, Portage, WI 53575, USA Abstract Liquid Silicone Rubber Injection Molding has been steadily gaining a foothold in many markets due to its ability to produce intricate elastomeric components with relatively short cycle times. The automotive industry employs silicone’s high degradation temperatures for engine sealing and medical markets rely on silicone for its biological inertness. Liquid Silicone Rubbers (LSRs) can be processed using slightly modified thermoplastic molding equipment, making them easy to integrate into existing business structures and facilities. In recent years, an increase in use has driven down the raw material cost of LSRs as to make them more competitive with historically less expensive thermoplastic elastomers, thus extending their use into new markets. An increase in specialized auxiliary equipment such as robotics and other demolding devices will further facilitate LSRs push to the mainstream of polymer manufacturing. Introduction Material Description Among elastomers, Liquid Silicone The two part material delivery system Rubber (LSR) has a relatively short history. employed by LSRs consists of an A component Developed during the late 1970s [1], LSR two which contains a catalyst and a B component component systems have quickly increased in which contains the crosslinking c
