Product Description
Antioxidant 1330 is a high-molecular-weight hindered phenolic antioxidant supplied as a white crystalline powder, with a melting point above 244°C. It is insoluble in water and exhibits varying solubility in organic solvents. At 18°C, its reported solubility is approximately 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.
Antioxidant 1330 helps protect polymers against thermo-oxidative degradation during high-temperature processing and long-term service. Its low volatility and favorable color stability make it suitable for polymer formulations where processing stability, heat-aging resistance, and the retention of material appearance are important. It is used in a range of industrial polymer applications, with performance depending on the polymer type, additive concentration, and processing conditions.

Application Scenarios
Antioxidant 1330 is a high-molecular-weight hindered phenolic antioxidant used to improve the thermo-oxidative stability of a wide range of polymer materials. It is suitable for selected thermoplastic polyesters, polyamides, styrenic resins, polyolefins, and elastomer systems, including polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyurethane, and natural rubber. Its compatibility and effectiveness depend on the specific polymer matrix, formulation, and processing conditions.
With its low volatility and effective antioxidant performance, Antioxidant 1330 helps protect polymer materials against oxidative degradation during processing and long-term use. It is particularly relevant to applications involving elevated processing temperatures or demanding heat-aging requirements.
Typical applications include:
Polyolefin Pipes and Fittings: Helps improve the thermal oxidative stability of PP- and PE-based materials used in pipe systems and related components.
Injection-Molded Products: Supports processing stability and long-term performance in molded polymer components.
Wire and Cable Materials: Helps protect suitable polymer insulation and jacketing compounds against thermo-oxidative degradation.
Engineering Plastics: Can be incorporated into selected polyester, polyamide, and styrenic resin formulations where long-term oxidative stability is required.
Elastomers and Rubber Products: Helps limit oxidation-related degradation in compatible elastomer formulations.
Antioxidant 1330 should be selected based on the polymer type, processing temperature, required service life, and compatibility with other additives. Formulation testing is recommended to determine the appropriate dosage and verify performance in the intended application.
