use
1. Crosslinking and modification of various thermoplastics (polyethylene, polyvinyl chloride, chlorinated polyethylene, EVA, polystyrene, etc.). Thermal crosslinking is generally 1-3%, plus dicumyl peroxide (DCP) is 0.2-1%; radiation 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. Compared with the cross-linking of peroxide system alone, it can significantly improve product quality and has no peculiar smell. Typically used for polyethylene, polyethylene/chlorinated polyethylene, polyethylene/EVA cross-linked cables and polyethylene high and low foam products.
2. Helped vulcanization of special rubber such as ethylene propylene rubber, various fluorine rubber, CPE (used with DCP, the general dosage is 0.5-4%), which can significantly shorten the vulcanization time, improve the strength, wear resistance, solvent resistance and resistance Corrosive.
3. Crosslinking of acrylic and styrene ion exchange resins. Compared with divinylbenzene crosslinking agent, it has less dosage, high quality, and can prepare ion exchange resin with excellent antifouling, high strength, large pore size, heat resistance, acid and alkali resistance, and oxidation resistance. This is a new type of ion exchange resin recently developed at home and abroad with excellent prospects.
4. Modification of polyacrylate, polyalkyl acrylate, etc. Can significantly improve heat resistance, optical properties and process performance. It is typically used for heat-resistant modification of ordinary plexiglass.
5. Modification of epoxy resin and DAP (diallyl phthalate) resin. It can improve heat resistance, adhesion, mechanical strength and dimensional stability. It is typically used to modify epoxy potting materials and encapsulating materials.
6. Crosslinking and modification of unsaturated polyester and thermoplastic polyester. 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, and the use temperature of modified products can reach above 180°C.
7. TAIC's own homopolymer-polytriallyl isocyanurate is a transparent, hard, heat-resistant, and excellent electrical insulation resin. It can also be used to bond glass and ceramics. It is typically used to manufacture multilayer safety glass.
8. Internal plasticization of polystyrene, copolymerization of styrene and TAIC, etc., can produce transparent and shatter-resistant products.
9. Protective agent for metal heat resistance, radiation resistance and weather resistance. TAIC prepolymer is baked on the metal surface, and its baking film has very good heat resistance, radiation resistance, weather resistance and electrical insulation. It is typically used to manufacture insulating materials such as printed circuit boards for microelectronic products.
10. Used as an intermediate for photocurable coatings, photoresist, flame retardant and flame retardant crosslinking agent. It is typically used to synthesize high-efficiency flame retardant TBC and flame retardant crosslinking agent DABC.
