Description

Wingstay 100 is a high-performance, hindered phenolic antioxidant widely used to protect polymers from oxidative degradation. Its primary value lies in its exceptional ability to extend the service life and maintain the physical properties of various synthetic materials by inhibiting chain-breaking autoxidation. This product is essential for manufacturers in the polymer and rubber industries who require reliable stabilization for their products against heat and oxygen exposure during processing and end-use.

Application

• Primary antioxidant for styrenic polymers (e.g., ABS, PS, HIPS) to prevent yellowing and embrittlement.
• Stabilizer for polyolefins (PP, PE) and engineering plastics to maintain mechanical properties during high-temperature processing.
• Critical additive in synthetic rubber and elastomer formulations to enhance thermal aging resistance.
• Used in adhesive and sealant formulations to ensure long-term performance stability.
• Protective agent for hydrocarbon-based fluids and lubricants against oxidative breakdown.
• Effective stabilizer in fiber and film applications where clarity and color stability are paramount.
