This product is easily soluble in acetone, chloroform and amide solvents, but not easily soluble in alkane and alcohol. Flash point (open cup method) 289.4℃. Ignition point: 302℃.

This product is a stylized phenolic antioxidant with three functional groups, no pollution, no staining. Because molecular weight and melting point are high, so the volatilization is extremely small, the migration is small, the resistance to water extraction is good, may endue the plastic good heat resistance oxidation and the resistance to light oxidation. Suitable for polyethylene, polypropylene, polystyrene, ABS resin, polyester, nylon, polyvinyl chloride, polyurethane, cellulose plastics and synthetic rubber, especially in polyolefin effect. The photothermal stability can be further improved by using ultraviolet absorbent or phosphite ester.

The toxicity of this product is low, the body weight of rats is 6800mg/kg via oral LD50 >, and that of rabbits is 10000mg/kg via oral LD50 >.

The chemical properties of this product are stable, no special storage requirements, should be moisture-proof, heat insulation.

The cardboard barrel is lined with plastic bag, 50Kg net per barrel.

Reference dosage: general dosage is 0.1%-0.25%.
