Overview
Silopren™ LSR 2670 is a two-component liquid silicone rubber used to injection mold parts. In addition to the properties of LSR 2070, it has better tear resistance, lower viscosity, and faster reactivity, hence a shorter cycle time. As a result, silicone rubber vulcanization temperature can be lowered while keeping the crosslinking rate constant. The vulcanizate's characteristics are unaffected by the elevated reactivity.
