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.

Chemark UV-389 is a liquid UV absorber designed specifically for the protection of polymers from the damage of UV light. Chemark UV-389 is more solvent soluble, has better resin compatibility, is less volatile, and provides a degree of stabilization that is significant better than other UV absorber based on benzotriazole or benzophenone which are commercially available in the market

Chemark UV-5411 is a high molecular weight ultraviolet light absorber of the hydroxy phenyl benzotriazole class. Its inherent off-white color renders itself more suitable for application where light color is critical. Its low volatility and high lipophilicity makes it especially useful where additive losses may occur during high temperature process.
