Description

Styrenated Phenol is a versatile phenolic antioxidant widely used to inhibit oxidative degradation in various materials. Its primary value lies in its ability to effectively scavenge free radicals, thereby extending the service life and maintaining the properties of polymers and other susceptible compounds. This product is essential for manufacturers in the polymer, rubber, lubricant, and adhesive industries seeking reliable stabilization solutions.

Application

• Primary antioxidant in polyolefins (e.g., polyethylene, polypropylene) to prevent thermal and oxidative degradation during processing and end-use.
• Stabilizer for synthetic rubbers and elastomers, including SBR, to protect against aging and maintain elasticity.
• Additive in industrial lubricants and greases to enhance oxidative stability and prolong oil life.
• Key component in adhesive and sealant formulations to prevent gelation and maintain bond strength.
• Stabilizing agent for hot-melt adhesives and other thermoplastic materials during high-temperature application.
• Used in the production of phenolic resins and as an intermediate for other specialty chemicals.

Quality Control

Our Styrenated Phenol is produced under a rigorous quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and performance. A Certificate of Analysis (COA) documenting these results is available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere for long-term preservation. Keep container tightly sealed when not in use.
