EPDM rubber extrusion exhibits anti-fire properties, but it is not better than CR rubber extrusion. This seal strip is used for common doors and windows. As a versatile rubber profile, it has a competitive price and covers a wide rubber market.
Foam rubber seals, during the manufacturing process, can be manipulated to exhibit certain unique traits. Color can be changed to meet clients’ requirements, density can be raised or lowered, and hardness is in the range of 25-30A. To some extent, EPDM sponge rubber has something in common with a foam rubber seal, but they are different.
