White Silicone Rubber Sponge Sheet

The silicone rubber sponge is the perfect product for times when a soft material that can be deformed easily is needed which standard rubber cannot provide. The silicone rubber sponge features a closed cell structure and a smoother outer wall which ensures that gas and liquids are unable to pass through the sponge. It provides excellent insulation and sealing properties. It can withstand temperatures from -40 to 200 degrees Celsius and has a tear strength of 200lb-f/inch. This product is also very easy to cut to size according to your own specifications.
