TMG-AIBN

Product description

TMG-AIBN, a widely used azo compound, serves as a cost-effective free radical source and polymerization initiator. Upon thermal decomposition, it releases free radicals and nitrogen gas. Its low molecular weight offers a high mole-to-pound efficiency compared to other initiators. TMG-AIBN is mainly used in free radical polymerizations, producing polymers with low branching, cross-linking, and polydispersity. It remains stable across various pH levels, resists redox reactions, and can be safely combined with other initiators without triggering radical-induced decomposition.

Applications / 應用

  • It is mainly used as initiator for polymerization of styrene, vinyl chloride, acrylonitrile, acrylates, and methacrylates.
  • It is also used in PVC for blowing agent
  • It is used in PU foam production and aids the creation of rigid and flexible foams for insulation, cushioning, and packaging applications.

Storage / 儲存

Azo compounds are unstable and can degrade over time and with exposure to heat. TMG-AIBN should be stored in a dry, well-ventilated area at temperatures below 24 ℃, away from sunlight, heat sources, flames, and ignition sources. Exposure to heat may lead to the degradation of the product and potentially hazardous decomposition, with a self- accelerating decomposition temperature (SADT) of 50 °C. It is important to keep the containers tightly sealed. If stored continuously below 8 ℃, TMG- AIBN has a shelf life of 30 months.

Packaging / 包裝
