LS-119 is a high molecular weight, non-polymeric hindered amine light stabilizer. It offers excellent thermal stability, low volatility, migration- and high-temperature resistance. It can perform well even in a weakly acidic environment. It decreases the interaction with agrochemicals, fillers, pigments and other additives. Suitable for use in polyethylene greenhouse film applications, polypropylene fibers, PP filled with talcum powder, TPO automotive parts. LS-119 is also suitable for PE, POE, EVA, PS, ABS, EPDM, PVC, PU, PA, POM, PBT, PET and PMMA applications.

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.

UNITECHEM UV-1 is liquid formamidine type ultraviolet absorber, which can effectively absorb ultraviolet light at a wavelength of 240-350nm. It has excellent photostability for polyurethane products.
