Description

Antioxidant 1076 is a high-performance, sterically hindered phenolic antioxidant widely recognized for its exceptional effectiveness in protecting polymers and organic materials from thermal and oxidative degradation. Its primary value lies in its ability to significantly extend the service life and maintain the physical properties of materials exposed to harsh processing and environmental conditions. This additive is essential for manufacturers in the plastics, synthetic fiber, rubber, and coatings industries seeking to enhance product durability and performance.

Application

• Primary antioxidant for polyolefins (PP, HDPE, LDPE) to prevent degradation during processing and long-term use.
• Stabilizer for engineering plastics such as ABS, polystyrene, and polycarbonate to maintain color and mechanical strength.
• Additive in synthetic fibers and elastomers to improve resistance to heat and oxygen exposure.
• Protective agent in adhesives, sealants, and coatings to prevent embrittlement and loss of adhesion.
• Stabilizing component in hot-melt adhesives and petroleum-derived products like lubricants and greases.
• Used in food-contact polymer applications where compliant grades are available, subject to regional regulations.
