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​.

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.

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.
