1: TCPP: trichloropropyl phosphate Chinese name: tris (2-chloropropyl) phosphate

2:CAS:13674-84-5

3: pure trichloropropyl phosphate is a colorless or pale yellow oily transparent liquid, tasteless. Compatible with the general organic solvent, insoluble in water and aliphatic hydrocarbons, and hydrolytic stability is good, in the alkaline solution is small This product is non-toxic, no obvious corrosive.

5: product use and dosage As the product also contains two elements of phosphorus and chlorine at the same time, the flame retardant effect is remarkable, and has plasticized, moisture, anti-static and so on, is added flame retardant. This product is mainly used for soft Rigid polyurethane foams, epichlorohydrin, polyethylenes, cellulose acetate, ethylcellulose resins and phenolic plastics, polyvinyl acetate, and gun-type foam sealants are particularly recommended for use in rigid polyurethane foams Thermal conductivity and hydrolytic stability, especially for ASTM84 (II), for compounds Polyurethane foams and unsaturated resins and phenolic plastics have low viscosity at low temperatures and are also used in conjunction with antimony trioxide to enhance flame retardancy effectiveness.

6: packaging and storage and transportation

Packing: galvanized iron drum, net weight 250KG. Transport: according to the general chemical specifications transport.
