triallylisocyanuraat

Triallylisocyanurate (TAIC) is a trifunctional monomer used as a crosslinking agent and modifier in various polymer systems. Its chemical structure consists of an isocyanurate ring with three allyl groups attached. This trifunctional nature allows TAIC to form a dense, three-dimensional network structure when polymerized or copolymerized with other monomers, leading to enhanced material properties.

TAIC is typically a clear, colorless liquid with a low viscosity. It is soluble in many organic solvents and exhibits good thermal stability. The presence of allyl groups makes it reactive in free-radical polymerization and crosslinking processes. It is often employed in applications requiring improved heat resistance, chemical resistance, mechanical strength, and electrical insulation properties.

Common applications for TAIC include its use in the production of crosslinked polyethylene for wire and cable insulation, as a co-agent in peroxide curing of elastomers such as EPDM and HNBR, and in the formulation of high-performance coatings and adhesives. It can also be incorporated into unsaturated polyester resins and vinyl ester resins to enhance their performance. The degree of crosslinking and the resulting properties can be controlled by the concentration of TAIC used and the reaction conditions.
