Application of Modified Chlorosulfonated Polyethylene Rubber in Sidewall Compound of All-steel Radial Tire
The application of modified chlorosulfonated polyethylene rubber(MCSM)in the sidewall compound of all-steel radial tires was studied.The results showed that by partially replacing natural rubber with MCSM in the sidewall compound,the FL and Fmax of the compound decreased,and the ts2 and t90 were prolonged.The hardness of the vulcanizate changed little,the modulus,tensile strength and tear strength decreased,and the elongation at break increased,while the ozone aging resistance,flexural fatigue resistance and weather and aging resistance properties improved.The appearance quality of tires was improved.
