Uses and synthesis of Light Stabilizer-944 powder

Light Stabilizer-944 powder, also known as Hindered Amine Light Stabilizer HS-944, molecular formula is C35H69Cl3N8, molecular weight 708.335. Light Stabilizer-944 CAS 70624-18-9 is mainly used in the production of low-density polyethylene film, polypropylene fibre, polypropylene tape, EVA film, ABS, polystyrene and food packaging. film, ABS, polystyrene and food packaging.

Applications / Functions of Light Stabilizer-944 powder

Light Stabilizer-944 Raw Materials is suitable for use in low density polyethylene films, polypropylene fibres, polypropylene tapes, EVA films, ABS, polystyrene and food packaging.

Light Stabilizer-944(UV-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 instancesUV-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.

Light Stabilizer-944(UV-944)? imparts excellent light stability to thin articles, particularly fibers and films. In thick cross sections it is specifically suitable for polyethylene articles. It is highly effective as a long-term thermal stabilizer in thin and thick articles and shows good extraction resistance.

Physicochemical Property of Light Stabilizer-944 powder

Light Stabilizer-944 powder is a white to light yellow granule or powder with a melting point of 100-135°C and a molecular weight of 2000-3100. It has excellent compatibility, extraction resistance and low volatility. Since Light Stabilizer-944 CAS 70624-18-9 is a high relative molecular mass stabiliser and contains only a large number of hypomethyl groups in the molecule, it is stable when treated with heat and oxygen.
