Antioxidant 1425 is a high molecular weight phenolic antioxidant containing phosphorus, designed to provide superior processing stability, long-term thermal resistance, and color retention. It is highly compatible with most substrates and resists extraction. Ideal for polyolefins, polypropylene fibers, polyesters, elastomers, adhesives, and tackifier resins, it also functions as an esterification catalyst for rosin esters​.

Light Stabilizer 944 by Suqian Unitechem 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)]]. Acts as a high molecular weight light stabilizer, with multiple functional groups. Exhibits solubility in organic solvents, slight solubility in methanol, and insolubility in water. Works with UV adsorbent because of its special structure and large molecular weight (3000). Light Stabilizer 944 is Used in film and fiber and in low density PE film, PP tape, EVA films, ABS, PP fiber, PE, polyacetals, polyamides, PUR, PVC, PVC blending material, PS, rubber.

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.

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.
