Nature and Use

It is a fireproof plasticizer with excellent hydrolysis stability, oil resistance and electric insulativity, high fungus resistance, good mutual solubility, excellent fireproof and plasticization property. The boil point is 220-270℃ at 530Pa and the flash point is 255℃ and the freeze point is below zero 24℃. It is not resolved in water and resolved in organic solvent such as chloro methane, aether, benzene and acetone. It is mainly used as plasticizer and fire retardant in PVC, polyethylene, artificial leather, film, sheet material, conveying belt, air duck, floor material, wire & cable, synthetic resin, plastic, rubber and cellulose, to improve the products' processibility, anti-pollution, mildew resistance and abrasion resistance; also used as lubricating grease antiwear, extreme-pressure additive and to synthesize incombustible hydraulic oil additive.
