Product Description
Silopren LSR 2070 is a standard two-component liquid silicone rubber for injection molding processes. Because of its excellent processing properties it is already used for a wide range of applications.

Vulcanisates consisting of Silopren LSR 2070 are distinguished by the following properties:
  • high thermal stability
  • excellent stability and flexibility at low temperatures
  • good rubber-like properties
  • long service life at dynamic stress
  • high stability to ozone and ultraviolet light
  • outstanding resistance to ageing
  • excellent dielectric behavior over a wide range of temperatures
  • not readily combustible, does not melt or drip
  • easy-pigmentable with LSR Colour Pastes
  • fulfill the requirement of KTW
  • meets flame retardant class UL 94 HB
  • compliance with FDA and BfR Recommendations

Because of the outstanding properties Silopren LSR 2070 is particularly suitable for the following elastomeric articles: sealing elements, O-rings, stoppers, keypads, bellows, vibration dampers, pressure cookers parts s.o.
