Silicone — Liquid Silicone Rubber Molding

Silicone

Premier Plastics Inc. is pleased to offer liquid silicone rubber (LSR) molding to our list of services. LSR molding is a thermoset process that mixes a two-component compound together and is heat-cured in the mold with a platinum catalyst to produce a final part. Parts made with LSR are created with an injection-molding process similar to conventional plastic injection molding, but unlike thermoplastic resin, which is melted before injection, LSR uses a two-part thermoset compound that is chilled before being injected into a heated mold and cured into a final part. Performance properties and fast cure cycles make liquid silicone rubber a good choice for small molded components.

Finished LSR parts are strong and elastic with excellent thermal, chemical, and electrical resistance. They maintain their physical properties and remain both flexible and elastic down to -58°F and up to 392°F. It can not be melted like a thermoplastic after it is set and it can withstand sterilization. LSR parts are also biocompatible, so they work very well for products that have skin contact. LSR parts are ideal for the automotive, medical and food appliance industries, particularly in the form of cables, gaskets, valves, and seals.

Silicone
Liquid silicone rubber is a good candidate for gaskets, seals and cushioning pads in portable communications, data acquisition instruments and ruggedized electronic devices where outdoor conditions are demanding. Silicone's excellent rebound, UV and ozone resistance makes it ideal for outdoor sealing and submerged gaskets.

Benefits

  • Wide hardness range and operating temperature (-58°F to 392°F)
