  • Vulcanizing aid: When synthetic rubber is vulcanized with peroxide, TMPTMA can improve corrosion resistance, aging resistance and increase hardness and heat resistance. It can be used for NBR, EPDM, and acrylic rubber.
  • Cross-linking agent: TMPTMA can reduce the radiation dose, shorten the radiation time, increase the cross-linking density, and has the characteristics of low precision, high cross-linking degree, low vapor pressure and fast curing speed. It can be used for light curing inks and photopolymer materials.
  • PVC: It is blended into the molding of all the PVC solutions of the car body sealant and caulking agent, such as: 100 parts of PVC, 60 parts of DOP, 2-4 parts of stabilizers, 0.02-0.6 parts of organic peroxides, TMPTMA 5-30 copies.
  • Wire coating material: used as the color coating material of the wire-the cross-linking agent of PVC resin, and a very thin layer of fine linear coating can be used to produce a tough and heat-resistant film.
  • Sealing adhesive: making anaerobic adhesives for packaging, sealing and fixing mechanical bolts.
