　　Use:

　　vulcanizing agent

　　When synthetic rubber is vulcanized with peroxides, TMPTMA can improve corrosion resistance, aging resistance and hardness. Heat resistance. TMPTMA plasticizes during mixing and has the original hardening effect of vulcanization. It can be used for NBR, EPDM, acrylic rubber.

　　Crosslinking agent

　　TMPTMA can reduce the radiation dose, shorten the radiation time, increase the cross-linking density, has the characteristics of low precision, high cross-linking degree, low vapor pressure and fast curing speed. It can be used for photocurable inks and photopolymer materials.

　　PVC

　　is blended into the car body sealant, caulking agent and all PVC solutions. For example: 100 parts of PVC, 60 parts of DOP, 2-4 parts of stabilizer, 0.02-0.6 parts of organic peroxide, 5-30 parts of TMPTMA

　　Wire coating material

　　is used as a cross-linking agent for PVC resin, a color coating material for wires, and a very thin layer of thin linear coating can be used to produce a tough and heat-resistant film

　　Recommended dosage:

　　When general rubber is used as crosslinking agent (bridging aid), it is recommended to add 2-4PHR

　　In EVA foam products, it is recommended to add 0.5-1.0PHR

　　In high hardness products, it is recommended to add 10-20PHR

　　Storage and transportation: The storage temperature is 16-27℃, avoid direct sunlight. Avoid contact with oxidants and free radicals. It can be stored in a dark PE barrel, and a certain space should be left in the container to meet the oxygen demand of the polymerization inhibitor. Use within six months has the best results. Transport as non-dangerous goods

　　Packing: 25kg/barrel (liquid) 200kg/barrel (liquid) 25kg/bag (powder)
