Supplied byMomentive Performance Materials- Last Updated on Aug 21, 2025

Silopren™ LSR 2660 by Momentive Performance Materials is a two-component liquid silicone rubber. It is not readily combustible, and it does not melt or drip. It is easily pigmented with LSR color pastes. It offers high reactivity, long service life at dynamic stress, high thermal stability, excellent stability and flexibility at low temperature. Exhibits low viscosity, short cycle times, excellent dielectric behavior over a wide range of temperature, good rubber-like properties, high stability to ozone and UV light. Shows resistance to aging and high tear. It reduces vulcanization temperature while maintaining a standard crosslinking rate. Designed for processing by injection molding. Silopren™ LSR 2660 is used in elastomeric articles like sealing elements, O-rings, stoppers, diaphragms, keypads, bellows, catheters, vibration dampers, switch cover, breast shields, spark plug boots and pressure cooker parts. Complies with KTW, WRAS, BfR recommendation, FDA 21 CFR 177.2600 regulations and UL 94 (HB) flame rating.
