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.

Light Stabilizer 770 is a low molecular weight hindered amine light stabilizer with low volatility, migration resistance, and high temperature resistance. It has synergetic effect with antioxidants and UV absorbers. Light Stabilizer 770 is suitable for polyolefin materials, cross-linked polyethylene, olefin copolymers and other polymer materials. It can often be used with other light stabilizers, antioxidants and UV absorbers, to further improve the anti-aging effect of materials. It provides very good light stability for thick sections but can also be used for articles with a high surface area such as films and tapes. It possesses broad compatibility and easy dispersion. Effectiveness of Light Stabilizer 770 is less dependent on the polymer's thickness and for this reason it provides good light stability in articles with higher specific surface such as films and tapes. It exhibits insolubility in water, but good solubility in methanol, ethanol and methylethylbenzene.
