Chemsorb-770 is a white or yellowish crystalline powder, soluble in benzene, chloroform, methanol, ethanol, ether, etc., insoluble in water.

Product use： Chemsorb-770 is a new generation of polymeric high molecular weight hindered amine light stabilizer. It has excellent processing thermal stability, good compatibility with resin, good water extraction resistance, and low volatility and mobility. Compared with the general low molecular weight hindered amine light stabilizer, it has excellent long-term anti-aging properties. This product can be used for polypropylene, polyethylene, polystyrene and ABS resins, as well as polyurethane, polyformaldehyde and polyester elastomers. Combined with antioxidant and ultraviolet absorbent, it has synergistic effect and can further improve the heat resistance and light aging effect of products.

Packaging and storage：It is packed in lined plastic bags, with a net weight of 25kg per box. Pay attention to avoid light, moisture and high temperature. Generally, the chemicals are stored in a dry and cool environment, and the recommended storage time is 12 months.
