Styrene-butadiene rubber (SBR) is one of the biggest general synthetic rubber varieties, and is also one of the
earliest industrialization production of rubber.It is the random copolymer of styrene and butadiene.Its
physical mechanism performance, processing performance and performance close to the natural rubber,
the use of some properties such as wear resistance, heat resistance, ageing resistance and curing rate is
more excellent natural rubber, but with a variety of natural rubber and synthetic rubber .
