Product Specification

Silicone sponge rubber is a flexible, lightweight elastomer with a closed-cell or semi-closed-cell foam structure. It is commonly used in gasket sealing, thermal insulation, and protective cushioning applications.

Product Features

● Density from 0.3g/cm3 to 0.9g/cm3

● Color in red, black, white, blue, yellow etc

● With good elastic, temperature resistance

● Hardness from 15 to 35shore A

● Silicone sponge rubber seal manufactured by silicone foam rubber, shapes depending on customer’s drawing or samples. Customized shape sizes such as round seal, rectangle, square, triangle and other customized shape etc.

Silicone sponge rubber profiles are designed to deliver consistent sealing performance under low compression.

Compared with dense silicone rubber, sponge profiles provide better cushioning and vibration damping, reduce noise and mechanical shock. The closed-cell structure also prevents water absorption, ensuring stable performance even in humid or wet environments.

Why Choose Silicone Sponge Rubber Profiles?

Silicone sponge rubber profiles combine softness, durability, and extreme temperature resistance, making them an ideal sealing solution where long service life, reliable compression recovery, and environmental resistance are required.
