Product Application of 1,3-Butadiene CAS#106-99-0
Product Application of 1,3-Butadiene CAS#106-99-0 1,3-Butadiene is a high-activity polymerization monomer that is effective for synthesizing elastic polymers and composite resin materials and has stable reaction performance in copolymerization systems. It is typically used as the core raw material in polymer formulation production, with its polymerization efficiency and material toughness depending on reaction temperature and monomer ratio.
In industrial applications, 1,3-Butadiene can be used as a fundamental substitute monomer for producing SBR rubber, polybutadiene rubber and ABS resin materials. It may be obtained through petroleum cracking fractionation or produced via industrial chemical extraction and purification processes.
