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 inhibit thermal and oxidative breakdown, thereby significantly extending the service life and maintaining the physical properties of sensitive materials. This product is essential for manufacturers in the rubber, plastics, and adhesive industries seeking to enhance the durability and stability of their formulations under demanding conditions.

Application

• Primary antioxidant in the production of synthetic rubbers, including SBR, BR, and NBR.
• Stabilizer for polyolefins (e.g., polyethylene, polypropylene) to prevent polymer chain scission and discoloration during processing and end-use.
• Critical additive in adhesive and sealant formulations to improve shelf-life and performance consistency.
• Protective agent for lubricants and greases, mitigating oxidative thickening and deposit formation.
• Used in the compounding of technical rubber goods such as hoses, belts, and gaskets to ensure long-term elasticity.
• Stabilizing component for thermoplastic elastomers (TPEs) and other polymer blends.

Quality Control

Our Wingstay 100 is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is tested against rigorous internal specifications, which typically include assay, melting point, and color. A Certificate of Analysis (COA) documenting these results is available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to minimize exposure to atmospheric humidity.
