The crosslinking agent is mainly used in a polymer material (rubber and thermosetting resin). Because the molecular structure of the polymer material is like a long line, when it is not crosslinked, the strength is low, it is easy to break, and there is no elasticity. The role of the cross-linking agent is to generate chemical bonds between the linear molecules, so that the linear molecules interact with each other. Together, a network structure is formed, which increases the strength and elasticity of the rubber. The crosslinking agent used in the rubber is mainly sulfur, and an accelerator is added.

1. Cross-linking and modification of various thermoplastics (polyethylene, polyvinyl chloride, chlorinated polyethylene, EVA, polystyrene, etc.). The thermal crosslinking is generally added in an amount of 1-3%, and the addition of dicumyl peroxide (DCP) is 0.2-1%; the amount of irradiation crosslinking is 0.5-2%, and DCP can be omitted. After cross-linking, the heat resistance, flame retardancy, solvent resistance, mechanical strength and electrical properties of the product can be significantly improved. It cross-links with a peroxide system alone to significantly improve product quality without odor. Typical for polyethylene, polyethylene / chlorinated polyethylene, polyethylene / EVA cross-linked cable and polyethylene high and low foam products.

2, ethylene propylene rubber, various fluoro rubber, CPE and other special rubber vulcanization (combined with DCP, the general dosage is 0.5-4%), can significantly shorten the curing time, improve strength, wear resistance, solvent resistance and resistance Corrosive.

3. Crosslinking of acrylic acid and styrene type ion exchange resins. It has less dosage and higher quality than divinylbenzene cross-linking agent, and can prepare ion exchange resin with excellent anti-fouling, high strength, large pore diameter, heat resistance, acid and alkali resistance and oxidation resistance. This is a newly developed ion exchange resin that has been newly developed at home and abroad.

4. Modification of polyacrylate, polyalkyl acrylate, and the like. It can significantly improve heat resistance, optical properties, and processability. It is typically used for heat resistant modification of common plexiglass.

5. Modification of epoxy resin and DAP (diallyl polyphthalate) resin. Heat resistance, adhesion, mechanical strength and dimensional stability can be improved. Typically used for the modification of epoxy potting compounds and encapsulants.

6. Crosslinking and modification of unsaturated polyester and thermoplastic polyester. It can significantly improve heat resistance, chemical resistance, dimensional stability, weather resistance and mechanical properties. It is typically used to improve the heat resistance of hot-pressurized unsaturated polyester FRP products. The modified product can be used at temperatures above 180 °C.

7. TAIC's own homopolymer, polytriallyl isocyanurate, is a transparent, hard, heat-resistant, electrically insulating resin that can also be used to bond glass and ceramics. Typically used to make multi-layer safety glass.

8. Polystyrene internal plasticization, styrene and TAIC copolymerization modification can produce transparent and crush-resistant products.

9. Metal heat-resistant, radiation-resistant and weather-resistant protective agent. TAIC prepolymer is baked on metal surface. Its baking coating has excellent heat resistance, radiation resistance, weather resistance and electrical insulation. It is typically used to make insulating materials such as printed wiring boards for microelectronic products.

10. Used as an intermediate for photocurable coatings, photoresists, flame retardants and flame retardant crosslinkers. Typically used to synthesize high efficiency flame retardant TBC and flame retardant crosslinker DABC.
