White powder,lumpy,or flaky product,non-toxic,concentrated distribution of molecular weight, specific gravity about 0.9 with high softening point but low fusion viscosity. It has good dispersion and fluidity, good electrical property and demoulding property, also with good light resistant and chemical resis tant properties.It is soluble with polyethylene, polypropylene, polyvinyl acetate,ethylpropyl rubber, butyl rubber, etc. The solubility is lower with polymethyl -methacrylate,polystyrene, ABS, PVC, etc.It is soluble in aromatic hydrocarbons. The product is used as processing auxiliary for PVC pipes,special shaped materials, film, wire and cable and other plastics and rubber.It is also used as the lubricant and demoulding agent of polyolefins and PVC. It can improve the fluidity of polyethylene, polypropylene and ABS and the demoulding property of polymethyl methacrylate and polycarbonate. For PVC, the product has better internal lubrication as compared with other external lubricants
