Introduction of UV-944

Light Stabilizing Agent 944 is hindered amine light stabilizing agent of polymerization type with macromolecular weight, which can be applied to PP, PE, EVA etc. When used in crosslinking polyethylene, it can manifest better effects. It can also be applicable to PPE, polyacetals, polyamnamees, polyurethanes, soft and hard PVC and PVC polymer blend etc. It also has good effects on styrene, rubber and adhesive substances. Particularly applicable to thin membrane and fibers.

Application Of UV-944

  • Hindered Amine Light Stabilizer 944 for low density polyethylene film, polypropylene fiber, polypropylene tape, EVA film, ABS, polystyrene and food packaging.
  • Applicable to various high polymers that demands stability under high light, including polypropylene, high-density polyethylene, ABS resin, PMMA, SAN, PVC, nylon, polyester,
    polyacetal etc.

  • Polymerized highly effective HALS iwth low volatility
    and degradation,a fine heat stalibizer and anti-oxidant,working well
    with AO and UVA;

  • Widely used in polyolefin(Such as PP,PE,HDPE,LDPE,LLDPE),
    PEX,co-polymers(such as copolyn of EVA,propylene and rubber),
    PPE,POM;PA;PU;soft and hard PVC blend and adherents
