Description

Antioxidant 1035 is a high-performance, hindered phenolic antioxidant widely recognized for its exceptional efficacy in stabilizing polymers and organic materials against thermal and oxidative degradation. Its primary value lies in providing long-term protection, thereby extending the service life and maintaining the physical properties of finished products. This additive is essential for manufacturers in the plastics, rubber, adhesives, and coatings industries who require reliable stabilization for their formulations. The compound is identified by CAS No. 41484-35-9.

Application

• Primary antioxidant in polyolefins (PP, HDPE, LDPE) for films, fibers, and molded articles.
• Stabilizer for engineering plastics and thermoplastic elastomers (TPEs) to prevent yellowing and embrittlement.
• Additive in adhesives and sealants to enhance shelf-life and performance stability.
• Protective agent in synthetic rubbers and latex to resist heat aging.
• Stabilizing component in industrial lubricants and greases to inhibit oxidation.
• Used in food-contact polymer applications where compliant grades are available.
• Additive for petroleum-based products and fuels to improve oxidative stability.
