Classification according to rubber sealing strip material There are three kinds of rubber materials for automobile sealing strips: dense rubber, sponge rubber and hard rubber. The hardness of hard rubber can reach shore A95. The rubber of the sealing strip is more resistant to aging, low temperature, moisture and chemical corrosion, especially It is an ozone aging resistant ethylene propylene diene rubber (EPDM). EPDM can be combined with steel belt, steel wire braided belt, TPE, flannel, flocking, PU coating Silicone coating and other composite, to ensure the waterproof, dust-proof, sound insulation, heat insulation, vibration damping, anti-wear and decorative effects of the automobile interior and the outside and its own. Generally, EPDM sealing strip can be used stably for more than ten years. Chloroprene rubber (CR) with good ozone resistance and good aging resistance can also be selected. In consideration of the process performance of common rubber materials, sometimes it is necessary to select the mixed rubber, such as natural rubber (NR) and Cr and styrene butadiene rubber (SBR) Rubber or polyethylene (PE), EPDM and NR rubber and plastics to improve ozone resistance.
