Hindered Amine Light Stabilizer 783 is poly[(6-[(1,1,3,3-tetramethylbutyl)amino]-1,3,5-triazine-2,4-diyl][(2,2,6,6-tetramethyl-4-piperidinyl)imino]-1,6-exanediyl[(2,2,6,6-tetramethyl-4-piperidinyl imino)]] and Poly-(N-β-hydroxyethyl-2,2,6,6-tetramethyl-4-hydroxy-piperidyl) succinate. Acts as a blend of two hindered amine light stabilizers. Delivers very good cost/performance benefits, when used in low concentration agricultural film system (LDPE, LLDPE). Hindered Amine Light Stabilizer 783 is used in applications polyolefin (PE, PP), polyurethane, polyformaldehyde, polyamide and polyester with elastomers and engineering plastics like ABS.

UNITECHEM AO-B215 is a physical blend of AO-1010 and AO-168. It is an excellent compound antioxidant with low toxicity, low volatility and high thermal stability. This product has good heat resistance and durability and can effectively prevent the oxidation and yellowing of plastics in the process of processing. The product is suitable for polyolefin, engineering plastics, elastomers, adhesives, rubber and petroleum products. It has good synergistic effect with HALS and UV absorbers.

UV-P is a benzotriazole type UV absorber. It has a high absorption in the wavelength of 270~340nm. It is also efficient for the light stabilization of polyvinyl chloride, unsaturated polyurethane, polystyrene, coatings and lacquers.

Widely used for PE, PP, POM, ABS resin and other compound resin, compound rubber and petro-products. The amount to be used may be 0.1%~0.5%.
