Description

22Thiobis4Methyl6Isobornylphenol is a high-performance phenolic antioxidant widely used in polymer stabilization. This compound is valued for its excellent ability to inhibit oxidative degradation, thereby extending the service life and maintaining the physical properties of sensitive materials. It is primarily needed by manufacturers in the polymer, rubber, and specialty chemical industries seeking to protect their products from thermal and oxidative stress.

Application

• Primary antioxidant in polyolefins (e.g., PP, PE) and other polymers to prevent thermal-oxidative degradation during processing and end-use.
• Stabilizer for synthetic rubbers and elastomers to maintain elasticity and prevent cracking.
• Additive in lubricants, greases, and industrial oils to enhance oxidative stability and prolong service intervals.
• Stabilizing component in adhesives and sealants to prevent premature curing and loss of adhesive properties.
• Protective agent for engineering plastics and thermoplastic elastomers (TPEs) used in automotive and electrical applications.
• Used in the formulation of masterbatches and polymer concentrates for consistent and efficient additive dispersion.
