Overview
Momentive Silopren™ LSR 2050 is a two-component liquid silicone rubber used for injection molding. It is translucent, easily pigmented, and processed in a 1:1 mix ratio. Silopren™ liquid silicone rubber (LSR) 2050 has high-temperature stability and flexibility at lower temperatures. Silopren™ LSR 2050 processing properties provide versatile capabilities in many silicone applications. Vulcanizates utilizing Silopren™ LSR 2050 will exhibit good rubberlike properties, dielectric behavior over a range of temperatures, and long service life. Additionally, it is not readily combustible.
