Description:This product is polymeric high molecular weight hindered amine light stabilizer.
It is a kinds of oligomer,which has very good processing thermal stability and excellent
compatibility with all kinds of resin.And light stabilizer 622 is a high molecular weight
compound which has very good water-extraction resistance，so,it is not easy to loss in the
processing or use. 622 can efficiently prevent the light, thermal, climate and water to degrade
with the high polymer. It be more superiority than a general low molecular weight HALS.
polymeric HALS has better thermal stability, low-volatility and mobility.As the light stabilizer,
it be suitable for PE, PP, PS, olefin copolymer, polyester, Soft PVC, polyurethane,
polyformaldehyde and PA etc.

Storage: Non-toxicity, Noninflammable, Non-explosive, No corrosion,Good storage stability.It
can use for food package.

Package:25KG/ Cardboard barrels or carton lined with plastic bag.Or according to the
customers’ requirements.
