1. High-Efficiency Thermal Stabilizer and Anti-Yellowing for Polyvinyl Chloride (PVC)

Suitable for rigid PVC (pipes, profiles, sheets) and flexible PVC (films, artificial leather, cable materials), it inhibits HCl release and thermal decomposition during high-temperature processing, significantly reducing yellowing and embrittlement. When combined with metal soaps and epoxy stabilizers, it can improve long-term heat resistance and weather resistance. Food contact grade addition: 0.1%–0.3%, industrial grade: 0.2%–0.5%.

2. Full-Chain Antioxidant Protection for Polyurethane (PU)

Used in PU flexible/rigid foams, elastomers, adhesives, and coatings, it inhibits the formation of polyol peroxides, preventing foam core burning and product yellowing, improving processing thermal stability and long-term aging resistance. Addition amount: 0.2%–0.4%. When combined with hindered phenols, it is suitable for automotive seats, insulation boards, shoe materials, etc.

3. Enhancement of Engineering Plastics against Thermo-Oxidative Aging

Compatible avec les élastomères et les plastiques techniques tels que l'ABS, le PC/ABS, le SBS et le SBR, il prévient le vieillissement thermo-oxydatif et la dégradation catalysée par les ions métalliques, améliorant ainsi la ténacité et la résistance aux fissures des produits. Il est souvent utilisé en synergie avec des antioxydants phénoliques encombrés dans les pièces intérieures des automobiles, les boîtiers d'appareils électroménagers et les articles de sport, avec un niveau d'ajout de 0,2%-0,4%.

4. Processing and Long-Term Stabilization of Polyolefins (PP/PE)

In PP and PE, it works synergistically with primary antioxidants (such as Irganox 1010) to inhibit thermo-oxidative degradation during processing and use, protecting molecular weight and mechanical properties. Suitable for food packaging films, thin-walled injection molded parts, and automotive bumpers, with an addition level of 0.1%–0.3%. Food contact grade meets relevant compliance standards.

5. Anti-aging Protection for Elastomers and Rubber

Utilisé dans les caoutchoucs EPDM, NBR, néoprène, etc., comme antioxydant et passivant métallique, empêchant le vieillissement thermo-oxydatif et la dégradation catalytique par des métaux tels que le cuivre et le fer. Améliore la résistance à la fatigue et la durée de vie des produits extérieurs/à haute température tels que les bandes d'étanchéité, les tuyaux et les pneus. Dosage de l'additif : 0,3%-0,6%.

6. Long-term Protection for Wire and Cable Insulation Materials

Chondrates metal ions, inhibiting their catalytic oxidation of cross-linked PE, PVC, EVA, and other insulation layers. Suitable for power cables, communication cables, and automotive wiring harnesses, improving long-term aging resistance and insulation reliability, especially suitable for copper core cables and high-temperature applications. Additive dosage: 0.2%–0.4%.

7. Stabilizes Coating and Adhesive Systems

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

8. Synergistic Blending of Polymer Anti-aging Systems

Synergistically combines with hindered phenols, thioether antioxidants, and light stabilizers to construct a highly efficient anti-aging system, significantly 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. Blending ratios are optimized according to materials and application scenarios.

9. Food Contact Materials: Compliant and Stable

Low toxicity properties comply with FDA and other relevant standards. Used in food contact grade PVC, PP, PE, PU, ​​and other materials, such as food packaging films, seals, and containers. Ensures no harmful substance migration during processing and use. Addition levels are strictly controlled within 0.1%–0.3%.

10. Auxiliary Applications in Fine Chemical Synthesis

Serves as a peroxide scavenger, reducing agent, or catalyst ligand in organic synthesis. Participates in selective reactions of pharmaceutical intermediates and specialty chemicals, reducing side reactions and ensuring the purity and yield of target products. Suitable for synthesis scenarios requiring strict control of oxidative impurities.
