Chemical name

 

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-hexanediyl [(2,2,6,6-tetramethyl-4-piperidinyl)imino]]

 

 

Introduction

UV 944,Horsorb 944 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.

 

Physical properties

Appearance:   Light yellow crystalline powder

Melting range:  100-135

Residue on ignition:   0.1% max

Transmittance:  425nm:  80% min

500nm:  85% min

 

Advantage

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.Unsturated Polyester: 0.2-0.5wt% for PS based on solids.
