Antioxidant HG-330 is a high molecular weight polyhindered phenolic antioxidant with low volatility and chemically stable properties, which can be safely and effectively used in a variety of polymer applications. In addition to polyolefin, it is also successfully used in thermoplastic elastomers, engineering plastic blends and alloys, hot melt adhesives and viscosifiers and other fields. Its excellent strength and comprehensive stability greatly improve the characteristics of many polymers, so that they do not degrade during processing and can be used for a long time under harsh conditions. Stable processing under high temperature, good heat resistance, no pollution, no discoloration and low toxicity. White crystalline powder, soluble in benzene, acetone, chloroform and other organic solvents, slightly soluble in ethanol, insoluble in water. Reference dosage: The general dosage is：0.05～0.3%.
