Applications
1. Polyolefins Processing & Long-Term Stability The industry-standard hindered phenol primary antioxidant for PP and PE processing. Provides excellent processing stability and long-term thermal protection, preventing degradation, discoloration and mechanical property loss in films, pipes, molded parts and fibers.
2. Engineering Plastics Effective stabilization for ABS, PS, POM, PA, PET and other engineering plastics. Maintains color, mechanical strength and service life under high processing temperatures and demanding end-use conditions.
3. Thermoplastic Elastomers & Rubber Protects SBS, SEBS, TPE and rubber compounds from thermo-oxidative aging. Delivers lasting flexibility, elasticity and appearance retention in automotive, footwear and consumer applications.
4. Fibers & Films Ensures stable spinning, drawing and extrusion of synthetic fibers and films. Low volatility minimizes plate-out and die build-up, improving process cleanliness and product consistency.
5. Hot Melt Adhesives & Sealants Prevents viscosity drift, discoloration and gel formation in hot melt adhesives during prolonged high-temperature service. Extends adhesive performance and shelf life.
6. Food-Contact & Specialty Applications Compliant with food-contact regulations for packaging materials. High purity, low ash and consistent quality support safe, reliable use across specialty polymer applications.
