Typical usage ratio

• 0.05%–0.10% by weight in polypropylene and high-density polyethylene resins (final dosage often adjusted based on melt index, product thickness, and exposure severity)

Downstream process integration

• Added to polymer melt with masterbatch or directly mixed during compounding prior to extrusion or molding
• Verified by QC sampling and melt-flow analysis to ensure homogeneous dispersion

Final product types

• BOPP film and cast film for food packaging
• Injection-molded automotive interior panels
• Blow-molded bottles for consumer liquids
• Pipes and profiles for infrastructure use

2. Engineering Thermoplastics for Electronics and Appliances

Producers of polycarbonate, ABS, and other high-value thermoplastics rely on our antioxidant to maintain dielectric strength and mechanical properties in electronic housings and appliance parts.

4. Coatings and Adhesives for Construction and Automotive Sectors

Manufacturers of high-durability coatings and solvent-free adhesives integrate our antioxidant during production to ensure UV and thermal stability for exterior and interior applications. Its function preserves polymer binder integrity, suppresses yellowing, and sustains adhesive bond performance over long-term field exposure, an essential criterion to comply with architectural and transportation sector regulations.

Industry compliance standards

• ASTM D4587 (Fluorescent UV exposure of coatings)
• EN ISO 11341 (Artificial weathering of paints and varnishes)

• Final performance validated by accelerated aging and QUV-B testing in technical QC labs

Final product types

• Exterior building paints and protective metal coatings
• Automotive OEM and refinish topcoats
• Epoxy and polyurethane construction adhesives
• Wood varnishes for professional carpentry

5. Polyester Fiber Production for Textiles and Industrial Yarns

Producers of polyester staple and filament fibers add our antioxidant at precise stages to prevent melt degradation and discoloration during continuous spinning.
