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

Kompatibel dengan elastomer dan plastik rekayasa seperti ABS, PC/ABS, SBS, dan SBR, mencegah penuaan termo-oksidatif dan degradasi yang dikatalisis oleh ion logam, meningkatkan ketangguhan produk dan ketahanan retak. Sering digunakan secara sinergis dengan antioksidan fenolik yang terhambat pada komponen interior otomotif, rumah peralatan, dan peralatan olahraga, dengan tingkat penambahan 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

Digunakan pada EPDM, NBR, karet neoprena, dll., sebagai antioksidan dan pasifator logam, mencegah penuaan termo-oksidatif dan degradasi katalitik oleh logam seperti tembaga dan besi. Meningkatkan ketahanan lelah dan masa pakai produk luar ruangan/suhu tinggi seperti strip penyegel, selang, dan ban. Dosis aditif: 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.
