1. Polymer Industry

• Plastics and Rubber Additive

• Thermal Stabilizer in Polymers: Used in polyolefins (e.g., PE, PP), polystyrene (PS), ABS, and synthetic rubbers (e.g., SBR, EPDM) to prevent chain scission and cross-linking during processing (e.g., extrusion, injection molding) and long-term use.

• Anti-Aging Agent: Inhibits oxidative degradation in automotive parts, electrical insulation, pipes, and packaging materials, extending service life and maintaining mechanical properties (e.g., tensile strength, flexibility).

• PVC and Polyurethane: Stabilizes flexible PVC compounds (e.g., cables, flooring) and polyurethane foams (e.g., furniture, automotive seats) against heat and oxidative stress.

2. Lubricants and Fuel Additives

• Motor Oils and Industrial Lubricants

• Antioxidant in Lubricants: Prevents the formation of sludge, varnish, and acid byproducts in engine oils, hydraulic fluids, and greases, enhancing lubricant longevity and reducing maintenance costs.

• Fuel Stabilizers: Added to gasoline, diesel, and biofuels to inhibit gum formation and oxidative degradation during storage, ensuring fuel quality and engine performance.

3. Petrochemicals and Synthetic Fibers

• Synthetic Fibers (e.g., Nylon, Polyester)

• Protects fibers from oxidative damage during spinning and processing, maintaining colorfastness and resistance to mechanical stress in textiles, carpets, and industrial fabrics.

• Petroleum Products: Used in waxes, resins, and bitumen to improve thermal stability and resistance to weathering in applications like roofing materials and road paving.

4. Food Packaging and Contact Materials

• Indirect Food Contact Applications

• Approved for use in food-grade plastics (e.g., PE/PP films, bottles) as an antioxidant under regulatory frameworks like FDA 21 CFR §178.2010 and EU Regulation (EC) No 10/2011, ensuring safety in packaging for dry foods, beverages, and pharmaceuticals.

5. Adhesives and Coatings

• Thermosetting Resins (e.g., Epoxy, Phenolic)

• Prevents oxidative degradation in adhesives, paints, and varnishes, improving shelf life and performance in high-temperature environments (e.g., industrial coatings, aerospace adhesives).

• Pressure-Sensitive Tapes: Stabilizes rubber-based adhesives against aging, maintaining tackiness and adhesion over time.

6. Pharmaceuticals and Agrochemicals

• Pharmaceutical Excipients

• Used in polymer-based drug delivery systems (e.g., sustained-release tablets) to protect active ingredients from oxidation during manufacturing and storage.

• Pesticide Formulations: Stabilizes oil-based insecticides and herbicides, preventing degradation of active components in agricultural sprays.
