Closed Cell Sponge Rubber
Nitrile (Buna-N)
Overview
Nitrile sponge rubber, also known as Buna-N, offers exceptional resistance to oils, greases, and petroleum-based substances, making it a strong choice for industrial and automotive sealing applications. Its closed-cell structure blocks moisture, dust, and chemicals, while its lightweight, compressible form ensures reliable gasket and cushioning performance. SRP often applies pressure-sensitive adhesive backing for applications requiring fast and secure installation.
