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, 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 the coextrusion products. The two-hardness rubber seal is better than other rubber seal stripes, and it can cater to more industries’ needs.
