2,2’- azobisisobutyronitrile (AIBN Silicium) is usualy used in polymerisation reactions to reduce the residual monomer content or to initiate or terminate the polymerisation process. Also use for:

  • for the polymerization of monomers like vinyl chloride, vinyl acetate, ethylene, styrene, methyl methacrylate, etc.
  • as a chemical blowing agent for section rigid PVC foams when the processing temperature range is 100-120 ºC
  • as a initiator in manufacture of nytron fibre
  • for initiating of process of chlorination of dichloroethane
  • in the manufacture of silicone rubber foam
  • in the manufacture of acrylic sheet, bangles, tubes, rods etc.
