The shock absorbing pad is generally characterized by the fact that the molecular structure is mainly cis structure, so the elasticity, crack resistance and dynamic performance are excellent, the anti-shock function of the rubber pad is ensured, and the life of the rubber pad is ensured, and the hardness is about 55.
Solid tire shockproof pad has good resilience, although it is lower than natural rubber, butadiene rubber and isoprene rubber, but its resistance to aging, corrosion, chemical medium and high pressure steam is dominant, so comprehensive comparison should be used. EPDM is good. Shock absorber rubber has long been the only compound with NR. In recent years, in order to meet the ever-increasing requirements for heat resistance and oil resistance of automobiles, IIR, EPDM, NBR and CR have also been used, and even microporous PU elastomers and TPE thermoplastic elastomers have appeared. In addition, according to the requirements of automobiles, in order to achieve the goal of weight reduction, it has begun to manufacture plastic rubber-impact rubber products by replacing plastic with plastic. Ethylene-propylene rubber vulcanizate hardness can be between 25-95A.
