Application of nitrogen flame retardant in polystyrene

 

The correct definition of flame-retardant grade EPS is actually a self-extinguishing material, that is, the material will be burned when it is exposed to fire and melts quickly, but it will extinguish itself when it leaves the fire source.

Hajlime n et al. Prepared flame retardant polystyrene (including polyphenylene ether) by using triphenylphosphate containing phenolic hydroxyl group and melamine cyanurate as flame retardant, and studied their interaction. The hydrogen bond formed between hydroxyl group and amino group on triphenylphosphate indicated that triphenylphosphate had Compatibilization and synergistic effect on meamine C, nuate. This not only solves the problem of compatibility between nitrogen flame retardant and resin, but also makes the resin have excellent fluidity, heat resistance and impact resistance at the same time, and solves the contradiction between the improvement of flame retardancy and the decline of other mechanical properties.

Our company-Leili Chemical Co.,Limited specializes in the production of polystyrene series products, which are widely used in the construction and packaging industries. We specialize in export trade and welcome customers to cooperate with us.
