Overview
Silopren™ LSR 2003 is a two-component liquid silicone rubber (LSR) used to injection mold low-durometer parts. As a liquid silicone rubber, it is clear, can be easily pigmented, and is processed in a 1:1 mix ratio. Silopren™ LSR 2003 is nontacky, making it suitable for consumer goods applications where sensory characteristics are important.
