Description

This product is light yellow powder, with molecular weight of 358 and melting point of 154-158 ℃, soluble in styrene, benzene, toluene and other solvents. It can strongly absorb ultraviolet light within 300 to 400 nm, and the absorption peak is at 353 nm. It is with minimal volatility, good compatibility with the polyolefin, and resistance to high temperature processing, good color fixation and excellent resistance to washing. Therefore, it is especially suitable for PE, PP, PVC, polymethyl methacrylate, polyformaldehyde, unsaturated polyester, polyurethane, ABS resin, natural rubber, synthetic rubber, latex, paint, etc.. It generates significant synergies when used in mixture with antioxidants especially DLTP. General dosage is 0.1 to 0.3%.
