氯丁橡胶(CR)是以2-氯-1,3-丁二烯为主要单体,通过均聚或共聚反应制得的一种弹性体。由于氯丁橡胶分子链中含有极性氯原子基团,一方面保护双键使其活性减弱,另一方面又使聚合物对非极性物质有很大的稳定性,因而氯丁橡胶的耐光、耐热、耐老化、耐油以及耐化学品腐蚀性能均优于天然橡胶,尤其是耐臭氧老化性、耐天候以及耐燃性能更为突出。另外还具有良好的物理机械性能和电性能,能在苛刻而恶劣的环境条件下使用,且制品寿命很长,其综合性能是天然橡胶和其他合成橡胶所无法比拟的。在汽车工业、家具制造、制鞋、建筑工业上PVC地毯敷设和防水涂膜、铁路枕木垫片、隧道构件、车厢密封体、矿用和船用电缆
Neoprene (CR) is an elastomer prepared by homopolymerization or copolymerization of 2-chloro-1,3-butadiene as the main monomer. As the neoprene molecular chain containing polar chlorine atom groups, on the one hand to protect the double bond to reduce its activity, on the other hand make the polymer has a great stability of non-polar substances, so neoprene light , Heat resistance, anti-aging, oil resistance and chemical corrosion resistance are better than natural rubber, especially ozone aging resistance, weather resistance and flame resistance is more prominent. In addition also has good physical and mechanical properties and electrical properties, can be used in harsh and harsh environmental conditions, and the product life is very long, its overall performance is unmatched by natural rubber and other synthetic rubber. In the automotive industry, furniture manufacturing, footwear, construction industry, PVC carpet laying and waterproof coating, railway sleepers gasket, tunnel components, compartment seals, mining and marine cables
