Message
Silopren LSR 3485/50 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 typically starts between a few hours and one day after vulcanization.

Key Features and Benefits
Vulcanizates consisting of Silopren LSR 3485/50 liquid silicone rubber are typically distinguished by the following properties:
  • 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 3485/50 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
