Cocrosslinking agent(TAC)

 Under normal temperature, TAC is a lightly yellow to colorless liquid or crystalline, and it has melting point 25-27℃, density 1.1133g/mL(30℃), viscosity 1.26×10-2 Pa·s (30℃) and refractivity 1.5049 (25℃). It is insoluble in water, while is soluble in ethanol, acetone, and heptane, petroleum ether, solvent oil, soybean extracted oil, and halohydrocarbon. Under normal temperature, it has stable properties and may be stably stored for a long period.

Application fields

  • Crosslinking agent TAC (triallyl cyanurate) is a crosslinking agent for trifunctional reaction, and it can remarkably improve the strength, rigidity and heat resistance of plastic products and it can allow the products work at 250℃ for long time.

  • It is a novel crosslinking agent for high-performance unsaturated polyester and acrylate series products and is especially for the high-temperature resistant and high strength glass fiber reinforced  plastic(GFRP) products.

  • It may be used as the curing accelerator for highly saturated rubber in the rubber and cable industry to improve the curing effect, and used as the photosensitizer for radiation cross-linking of polyolefin to reduce the irradiation.
