3- Properties
The appearance is the white crystallization powder 182 of point - 186. 5 degrees Centigrade Flash point is 257 degrees Centigrade Apt to is it on toluene , two chlorine methane ,etc. organic solvent , is it on ester type , dissolve on ink to dissolve a little to dissolve.
4- Applications
The product is a kind of high-effective solid phosphite ester antioxidant, which is superior to other phosphite ester in the effective protection of polymers' color. It is often blended with phenolic principal antioxidant (such as AT-10) to prepare composite antioxidant which improves the thermo-stability of polymer processing, thus making it widely applied in PE, PP, PS, PA, PC, ABS and many other polymer materials.
