Antioxidant 1330 is a high-performance hindered phenolic antioxidant. It takes the form of fine white crystalline powder and boasts a melting point higher than 244°C. The high melting point greatly lowers its volatility under heat, allowing it to stay effective during continuous high-temperature manufacturing processes.

The product is completely insoluble in water. Tested at 18°C, its solubility in common solvents is shown below: 20 g/100 g in benzene, 31.9 g/100 g in methylene chloride, 1.7 g/100 g in methylcyclohexane, 0.2 g/100 g in methanol and 0.1 g/100 g in isopropyl alcohol. Its distinct solubility profile supports uniform dissolution and dispersion within various polymer formulations and helps prevent undesired precipitation.

It delivers outstanding processing stability and reliable heat resistance when exposed to elevated temperatures. Capable of suppressing thermal oxidative degradation, it protects polymer materials from molecular chain fracture and performance deterioration induced by heat. Furthermore, Antioxidant 1330 features low toxicity, non-discoloration property and will not bring contamination to finished goods. Thanks to these comprehensive strengths, it can be widely deployed across numerous industrial polymer application fields.
