High Molecular Weight Hindered Amine Light Stabilizer (HALS)
Chemical Name :
Poly[[6-[(1,1,3,3-tetramethylbutyl)amino]-s-triazine-2,4-diyl]-[(2,2,6,6-tetramethyl-4-piperidyl)imino]-hexamethylene-[(2,2,6,6-tetramethyl-4-piperidyl)imino]]
Introduction: LS 944 is a high molecular weight hindered amine light stabilizer (HALS). It shows excellent compatibility, high resistance to extraction and low volatility.
Details:
CAS Number 70624-18-9
Molecular Weight Mn = 2000-3100
Properties:
Appearance and behaviour White to slightly yellow granules
Melting temperature ≥100℃ Flash point >150℃
Applications: LS 944 areas of application include polyolefins (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomers.
In addition in certain instances LS 944 is highly effective in polyacetals, polyamides, polyurethanes, flexible and rigid PVC, as well as PVC blends and in certain styrenic elastomer and adhesive specialty applications.
Features/Benefits LS944 imparts excellent light stability to thin articles, particularly fibers and films. In thick cross sections it is specifically suitable for polyethylene articles. In addition its use is recommended for applications requiring indirect food contact approval.
Packing：LS-944 is available in powder form in a 25kg fiber drum or 25kg carton with an inner PE liner. |
