Characteristics and uses:
The product is a polymeric high molecular weight hindered amine light stabilizer, it is an oligomer with good processing thermal stability and good compatibility with various resins, and because it is a high molecular weight compound, it has good water extraction resistance. Therefore, in the process or in use, the water extraction resistance is good, not easy to lose. This product can effectively prevent the degradation of polymers by light, heat, climate, and moisture. It is superior to the general low molecular weight hindered amine light stabilizer (HALS).
Light stabilizer 622
Many. Polymeric hindered amines have better heat resistance, pullout resistance, lower volatility and mobility. As light stabilizers, this product is suitable for polyethylene, polypropylene, polystyrene, olefin copolymers, polyester, soft polyvinyl chloride, Polyurethane, polyformaldehyde, polyamide, etc.
