皮带橡胶材质SBR与NBR有什么区别？
What is the difference between SBR and NBR?
>> 丁苯橡胶（SBR)
>>Styrene butadiene rubber (SBR)
又称聚苯乙烯丁二烯共聚物。其物理机构性能，加工性能及制品的使用性能接近于天然橡胶，有些性能如耐磨、耐热、耐老化及硫化速度较天然橡胶更为优良，可与天然橡胶及多种合成橡胶并用，广泛用于轮胎、胶带、胶管、电线电缆、医疗器具及各种橡胶制品的生产等领域，是最大的通用合成橡胶品种，也是最早实现工业化生产的橡胶品种之一。
Also known as polystyrene butadiene copolymer. Its physical mechanism performance, processing performance and product use performance are close to that of natural rubber. Some properties, such as wear resistance, heat resistance, aging resistance and vulcanization speed, are better than that of natural rubber. It can be used in combination with natural rubber and a variety of synthetic rubber. It is widely used in the production of tires, tapes, rubber tubes, wires and cables, medical appliances and various rubber products. It is the largest general-purpose combination It is also one of the earliest rubber varieties to realize industrial production.
>> 丁腈橡胶（NBR）
>>Nitrile rubber (NBR)
是一种合成橡胶，由丙烯腈与丁二烯单体聚合而成的共聚物，耐油性（尤其是烷烃油）好、耐磨性高、气密性好、耐热性好、粘接力强、耐老化性能较好等优点。
It is a kind of synthetic rubber, which is polymerized from acrylonitrile and butadiene monomer. It has the advantages of good oil resistance (especially alkane oil), high wear resistance, good air tightness, good heat resistance, strong adhesion and aging resistance.
