Momentive Performance Materials Silopren LSR 3786 20 TP 3944 Liquid Silicone Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber; Liquid Silicone Rubber (LSR)
Material Notes:	Silopren LSR 3786/20 is a two-component liquid silicone rubber for injection molding processes. This material is an excellent candidate to consider for the manufacture of elastomeric articles requiring self-lubricating properties. The self-lubricating effect is achieved by a fluid which exudes out of the vulcanizate over an extended period of time. It starts typically between a few hours and one day after vulcanization. Silopren LSR 3786/20 liquid silicone rubber shows a low compression set after vulcanization without post-curing. Vulcanizates consisting of Silopren LSR 3786/20 liquid silicone rubber are typically distinguished by the following properties: low compression set without post-cure, self-lubricating properties, low viscosity, fast cure, high thermal stability, outstanding resistance to aging, easy to color. Because of the outstanding properties, Silopren LSR 3786/20 liquid silicone rubber is an excellent candidate to consider for use in wire harness applications for the following elastomeric articles: cable seals, mat seals, grommets, gaskets, plug seals.
