Description

[3-[3-(4-hydroxy-3,5-ditert-butyl-phenyl)propanoyloxy]-2,2-bis[3-(4-hydroxy-3,5-ditert-butyl-phenyl)propanoyloxymethyl]propyl] 3-(4-hydroxy-3,5-ditert-butyl-phenyl)propanoate is a high-performance, multi-functional phenolic antioxidant, specifically a pentaerythritol tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate) derivative. It matters as a critical additive for preventing oxidative degradation and extending the service life of polymers and other sensitive materials. This compound is essential for formulators and manufacturers in the plastics, rubber, and synthetic lubricant industries who require robust stabilization against heat and oxygen.

Application

• Polymer Stabilization: Primary antioxidant for polyolefins (PP, PE), engineering plastics, and synthetic rubbers to prevent thermal-oxidative degradation during processing and long-term use.
• Lubricant & Grease Additive: Used in synthetic lubricants, engine oils, and industrial greases to inhibit oxidation, reduce sludge formation, and extend oil drain intervals.
• Adhesive & Sealant Formulations: Enhances the thermal stability and longevity of hot-melt adhesives, polyurethane sealants, and other polymer-based bonding systems.
• Elastomer Protection: Provides antioxidant protection for styrene-butadiene rubber (SBR), ethylene-propylene-diene monomer (EPDM), and other elastomers against cracking and loss of elasticity.
• Food Contact Material Compliance: Suitable for use in polymer applications requiring compliance with relevant food contact regulations (subject to specific grade and regional approval).
• Masterbatch & Compound Production: An effective component in antioxidant masterbatches and polymer compounds for uniform dispersion and simplified handling.

Quality Control

Our production of Antioxidant 1010 adheres to stringent quality management systems. Each batch is analyzed to ensure it meets precise specifications for purity, melting point, and phenolic content. Certificates of Analysis (COA) documenting key parameters are provided to guarantee traceability and compliance with industry standards. We support formulations requiring consistency for global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its nature as an organic compound that is easily oxidized, prolonged exposure to air should be minimized. Keep away from strong oxidizing agents and heat sources.
