Uses:
The product is a kind of hindered amine light stabilizer (HALS). It is mainly used as UV light stabilizers for follow materials: thermoplastic polymer materials such as polyacetals, acrylonitrile-butadiene-styrene copolymer (ABS), styrene-acrylonitrile copolymer (SAN) , and such as engineering plastics polyethylene (PE), polypropylene (PP), polyamides (PA), acrylonitrile-styrene- acrylate copolymer (ASA) and high impact polystyrene (HIPS), and other thermoplastic polyolefin elastomer (TPO), polyurethanes (PU) etc. and it is widely used in fiber, film, sheet, pipe, tape, molded and the like product maded from the above materials. In addition, this product is also an antioxidant additives for ashless lubricant.
