Main purpose:

Widely applied as anti-flaming agent in PVC, PP, PE, PS, ABS, PU and other plastic, with high anti-flaming efficiency, producing less effect on mechanic performance of basic materials( e.g. fire control uniforms, gloves, case of anti-flaming electronic equipment, anti-flaming carriage, anti-flaming wire and cable, etc. ).     · Used as filling agent and flame retardant in rubber industry.     · Used as covering agent in porcelain enamel and ceramics.     · Used as non-magnetic ceramics used for making pressure sensitive ceramics and magnet head parts in electronic industry.     · Used as white dye and flame retardant of paint in painting industry.     · Used as catalyze for organic synthesis

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. Whats 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.
