| Silopren LSR 3286/50 is a 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 typically starts between a few hours and one day after vulcanization. Silopren LSR 3286/50 liquid silicone rubber shows a low compression set after vulcanization without post-curing. Key Features and Benefits Vulcanizates consisting of Silopren LSR 3286/50 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 Potential Applications Because of the outstanding properties, Silopren LSR 3286/50 liquid silicone rubber is an excellent candidate to consider for use in wire harness applications for the following elastomeric articles: cable seals grommets gaskets plug seals&& |
