Overview
Silopren™ LSR 2660 is a two-component liquid silicone rubber used to injection mold parts. In addition to the properties of LSR 2060, it has a lower viscosity and faster reactivity, hence, a shorter cycle time. With this two-component liquid silicone grade, it is possible to reduce the vulcanization temperature while keeping a standard cross-linking rate. This increased reactivity will not affect the properties of the vulcanizate silicone.
