The Uses of TAIC

1. TAIC is used to produce various thermoplastics such as polyethylene, polyvinyl chloride, chlorinated polyethylene, EVA, polystyrene. The general addition amount of thermal cross-linking is 1-3%, plus 0.2-1% of dicumyl peroxide (DCP); the addition amount of radiation cross-linking is 0.5-2%, and DCP can be omitted.

2. After adding TAIC, 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 the product quality, and has no peculiar smell. Typically used in polyethylene, polyethylene/chlorinated polyethylene, polyethylene/EVA cross-linked cables and polyethylene high and low foaming products.

3. TAIC is used to produce rubber (combined with DCP, the general dosage is 0.5-4%). Adding CAIC can significantly shorten the vulcanization time, improve strength, wear resistance, solvent resistance and corrosion resistance.

4. TAIC is used for cross-linking of acrylic and styrene ion exchange resins. Compared with divinylbenzene cross-linking agent, TAIC has less dosage, high quality, and can prepare ion-exchange resins with excellent properties such as anti-fouling, high strength, large pore size, heat resistance, acid and alkali resistance, and oxidation resistance. This is a newly developed, promising new ion exchange resin.

5. TAIC is used for polyacrylate and polyalkylacrylate. Can significantly improve heat resistance, optical properties and process performance. Typically used for heat-resistant modification of ordinary plexiglass.

6. TAIC is used for epoxy resin and DAP (diallyl phthalate) resin. Improves heat resistance, adhesion, mechanical strength and dimensional stability. Typically used for modification of epoxy potting and encapsulating compounds.

7. TAIC is used for crosslinking and modification of unsaturated polyester and thermoplastic polyester. It can significantly improve heat resistance, chemical corrosion resistance, dimensional stability, weather resistance and mechanical properties. It is typically used to improve the heat resistance of hot-pressable unsaturated polyester FRP products, and the service temperature of the modified products can reach above 180°C.

8. Polytriallyl isocyanurate, the homopolymer of TAIC itself, is a transparent, hard, heat-resistant and excellent electrical insulation resin, which can also be used to bond glass and ceramics. Typically used in the manufacture of multilayer safety glass.

9. Internal plasticization of polystyrene, copolymerization modification of styrene and TAIC, etc., can produce transparent and shatter-resistant products.

10. Protective agent for metal heat resistance, radiation resistance and weather resistance. TAIC prepolymer is baked and plated on the metal surface. The baked coating has very good heat resistance, radiation resistance, weather resistance and electrical insulation. Typically used for insulating materials such as printed circuit boards in the manufacture of microelectronics.

11. Used as an intermediate for photocurable coatings, photoresists, flame retardants, and flame retardant crosslinking agents. Typically used in the synthesis of high-efficiency flame retardant TBC and flame retardant cross-linking agent DABC.
