Description

Antioxidant 1010 is a high-performance, sterically hindered phenolic antioxidant, also known as Pentaerythritol tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate). Its primary function is to inhibit oxidative degradation in polymers and other organic materials, thereby extending their service life and maintaining their physical properties. This additive is essential for manufacturers seeking to enhance the thermal stability and color retention of their products during processing and long-term use. It is widely utilized across the plastics, synthetic fiber, and rubber industries.

Application

• Primary antioxidant for polyolefins (PP, HDPE, LDPE) to prevent thermal oxidation during processing and in end-use applications.
• Stabilizer for engineering plastics such as ABS, polystyrene, and polycarbonate to maintain mechanical strength and appearance.
• Additive in synthetic fibers and elastomers to protect against degradation caused by heat and oxygen exposure.
• Key component in adhesive and sealant formulations to ensure long-term performance and shelf stability.
• Used in the stabilization of lubricants, greases, and transformer oils to prevent sludge formation and viscosity increase.
• Protective agent for food-contact compliant polymers, subject to relevant regulatory approvals.
