This product is a high-performance polymeric hindered amine light stabilizer (HALS), especially suitable for polyolefins (PP, PE, etc.), polyolefin copolymers,
In polymer products such as nylon, polyacetal, polyester, etc., it can effectively prevent the occurrence of photoaging phenomena, such as the decrease of mechanical strength and yellowing, and improve the weather resistance of products. Tiangang HS-944 can also be used for copolymers of polyolefin with EVA and PPO, polyoxymethylene (POM), nylon (PA), polyurethane (PU), soft and hard polyvinyl chloride (PVC) and PVC blends. In addition, Tiangang HS-944 also has good photostability to styrene, rubber and stickies.
