Description

Antioxidant 1098 is a high-performance, sterically hindered phenolic antioxidant widely recognized for its excellent stabilizing properties. It is critical for preventing oxidative degradation and extending the service life of polymers and other sensitive materials. This product is essential for manufacturers in the plastics, synthetic fiber, and elastomer industries who require reliable long-term thermal stability for their products.

Application

• Primary antioxidant for polyamides (nylon 6, nylon 66) and polyesters (PET, PBT).
• Thermal stabilizer for engineering plastics, synthetic fibers, and adhesives.
• Protective additive for polyurethane elastomers and coatings to prevent embrittlement.
• Stabilizing agent for lubricants, greases, and other hydrocarbon-based fluids.
• Used in the production of high-temperature resistant films and packaging materials.
• Key additive in masterbatches and polymer compounding to ensure consistent quality.
