BUNA-S (or STYRENE RUBBER)
This is the most important type of synthetic rubber which is produced by copolymerization of butadiene ,CH2 = CH- CH = CH2 (75% by weight) and styrene ,C6 H5 CH = CH2 (25% by weight).
1.Styrene rubber resembles natural rubber in processing characteristics as well as quality of finished products.
2.1t posses high abrasion-resistance, high load-bearing capacity and resilience
3.1t swells in oils and solvents.
1.Mainly used for the manufacture of motor tyres.
2. Other uses of this elastomer are floor tiles, shoe soles, gaskets, foot-wear components, wire and cable insulations, carpet backing, adhesive, tank-lining, etc.
