Application of butadiene
Butadiene is the main raw material of synthetic rubber (styrene-butadiene rubber, butadiene rubber, nitrile rubber, chloroprene rubber). With the development of rubber and plastic industry, styrene and butadiene are used to produce resin of various purposes (such as ABS resin, SBS resin, BS resin, MBS resin), so butadiene is playing more and more important role in resin production. What’s more, butadiene is used for ethidene norbornene (EPDM third monomer), 1,*-butanediol (engineering plastics), six dinitrile (nylon *6 monomer), sulfolane, anthrone, tetrahydrofuran production an other fields.
