Silopren* LSR 3366/50 liquid silicone rubber

Long-term heatstability – Self-lubrication

Silopren LSR 3366/50 is a two-component liquid silicone rubber for injection molding processes. Silopren LSR 3366/50 shows an excellent aging resistance after long term exposure to high temperatures and retains very good compression set also without post-curing under these conditions. This material is an excellent candidate to consider for the manufacture of elastomeric articles requiring self-lubricating properties like seals for electrical connectors in the automotive industry.

More About Silopren* LSR 3366/50 liquid silicone rubber

Demanding application in automotive electrical applications are exposed to higher heat over a longer time with advancements in engine technology and reduced packaging size. At the time higher expectations to vehicle reliability and service life lead to more higher levels in specifications, especially for long-term sealing force and temperature stability.

Silopren LSR 3366/50 has similar physical properties like the broadly specified in Silopren LSR 3286/50. But based on new formulation and manufacturing technology it moves the service temperature limit up by more than 25°C and achieves a similar level of the 1-day compression set after 6 weeks. This benefits the reliability of applications which are exposed to higher heat or have to service much longer or much more reliable than conventional self-lubricating LSRs.

Silopren LSR 3366/50 can be processed on conventional LSR equipment and achieves its physical properties without post-curing and without additives. The material has a whitish appearance and can be easily pigmented with LSR color-pastes available from Momentive.
