R-10480 Soft

R-10480 Soft silicone sponge rubber is a low compression set closed-cell sponge that can be used in most gasketing applications. This material is flexible and compressible and designed for use in extreme temperature ranges, with excellent weatherability, compression set resistance, electrical strength and non-stick properties. The R-10480 series was developed as an extremely low compression set silicone sponge material. Hanna rubber applies a pressure-sensitive acrylic or silicone adhesive to one side to offer excellent adhesion properties.
