CAS NO.: 71878-19-8

UV 944,Horsorb 944 is a polymeric light stabilizer, mainly applied in polyolefin plastic, such as PP and PE, in olefin copolymer, such as EVA and the combination of propylene and rubber. It is also used in polyphenylene oxide compound(PPE), polyacetals and polyamides, polyurethanes, PVC and PVC compound.

Advantages:
1. High compatibility with a wide range of polymers.
2. Better performances than ultraviolet light absorber, e.g. UV-327
3. Has coordinating function when used with ultraviolet light absorber.
4. It can be used in low volatile and slight transfer system, especially for film and fibre.

Applications:
1.Polyvinyl chloride: 0.1-0.5wt% for rigid PVC based on solids.
2.Polyurethane: 0.1-0.3wt% for PS based on solids.
3.Polyamides: 0.2-0.5wt% for PS based on solids.
4.Unsaturated Polyester: 0.2-0.5wt% for PS based on solids.
