1. Polyolefin (PP/PE) Processing Stabilization and Lubrication:

In PP and PE, it synergistically works with hindered phenols (such as Irganox 1010) to inhibit high-temperature extrusion/injection molding thermo-oxidative degradation, protecting molecular weight and mechanical properties while improving melt flowability. Suitable for thin-walled injection molded parts, food packaging films, automotive interior panels, etc. Addition amount: 0.1%–0.3%, meeting FDA food contact standards.

2. PVC Heat Stabilization and Anti-Yellowing:

Suitable for rigid PVC (pipes, profiles) and flexible PVC (films, artificial leather), it inhibits HCl release and thermal decomposition during processing, reducing yellowing and embrittlement. Combined with metal soaps and epoxy stabilizers, it improves heat resistance. Addition amount: 0.1%–0.3%, suitable for transparent products and food contact grade materials.

3. Engineering Plastics: Heat and Oxidation Resistance and Color Protection:

Used in ABS, PC/ABS, nylon, PET, etc., to prevent heat and oxidative degradation during high-temperature processing and long-term use, improving the color and toughness of products. Suitable for appliance housings, automotive parts, electronic components, etc. Addition level: 0.2%–0.4%.

4. Elastomer and Rubber: Anti-aging Agent:

Used as an antioxidant in EPDM, SBS, NBR, etc., to inhibit heat and oxidative aging and metal-catalyzed degradation, improving the fatigue resistance of outdoor/high-temperature products such as sealing strips, hoses, and tires. Addition level: 0.3%–0.5%.

5. Food Contact Material Compliance and Stability:

Low toxicity and compliant with relevant FDA standards. Used in food contact grade PP, PE, PVC, etc., such as packaging films, containers, and seals. Addition level controlled at 0.1%–0.3% to prevent the migration of harmful substances.

6. Stabilization of Coating and Adhesive Systems:

Prevents pre-crosslinking during storage and curing of solvent-based/water-based coatings and UV-cured adhesives, improves the weather resistance of alkyd resins and acrylic coatings, avoids coating delamination and gelation, suitable for outdoor architectural coatings, automotive refinish paints, etc., with an addition amount of 0.1%–0.3%.

7. Insulation Protection for Wires and Cables:

Chelates metal ions, inhibiting the catalytic oxidation of cross-linked PE, PVC, and EVA insulation layers by copper, iron, etc., improving the long-term aging resistance and insulation reliability of power cables and communication cables, with an addition amount of 0.2%–0.4%, suitable for high-temperature and humid environments.

8. Synergistic Compounding of Polymer Anti-aging Systems:

Synergistically combines with hindered phenols, thioether antioxidants, and light stabilizers to construct a highly efficient anti-aging system, improving the weather resistance, heat resistance, and yellowing resistance of materials, suitable for harsh environments such as outdoor building materials (plastic doors and windows, railings), and automotive exterior parts. The compounding ratio is optimized according to the materials.

9. Polyester and Polycarbonate (PC) Stabilizer:

Used in engineering resins such as PET and PC to inhibit thermo-oxidative degradation during processing and use, maintaining the transparency and mechanical properties of finished products. Suitable for beverage bottles, optical lenses, electronic device housings, etc. Additive dosage: 0.1%–0.3%.

10. Metalworking Fluids and Lubrication Systems:

As a metalworking fluid additive, it possesses both antioxidant and lubricating functions, inhibiting oil oxidation and deterioration, reducing tool wear. Suitable for cutting fluids, rolling oils, etc. Additive dosage: 0.5%–1.0%. It can also be used in synthetic lubricants to improve oxidation and anti-wear properties.
