Sponge rubber can be shaped into various industrial rubber products, including dual durometer profiles. By combining sponge rubber and solid rubber into a single part (such as bulb trim seals), different areas of hardness are achieved. Typically, sponge profiles are characterized as soft, medium, and firm. Choosing open cell foam or closed cell foam, depending on your application requirements. Dual Duromater is one of coextrusion products, two hardness rubber seal is better than other rubber seal strip, it can cater for more industries need.
