Overview
Silopren™ LSR 4655 SL is a family of liquid silicone rubber (LSR) for healthcare device designers looking to improve production by benefiting from increased lubricity from this portfolio. Specialized molders require a high-slip surface and cannot achieve this with traditional silicone rubber components.
