在汽车用橡胶制品中,传动轴保护罩原来使用的是CR,但对改善保护罩的臭氧龟裂性来讲,CR几乎是到了极限的范围。因此,采用耐臭氧性优良的氯化聚乙烯橡胶(CM),将是消除臭氧龟裂、提高耐久性的一种有效途径。就这一材料的开发而言,据说耐润滑脂性、低温特性、耐久性等水平 In the automotive rubber products, the original use of transmission shaft guard CR, but to improve the protective cover of the ozone crack in terms of CR is almost to the limit range. Therefore, using ozone-resistant chlorinated polyethylene rubber (CM) will be an effective way to eliminate ozone cracking and improve durability. In terms of the development of this material, it is said that grease resistance, low-temperature characteristics, durability and other levels
