Product Name:Antioxidant THP-EPQ
English Name:Antioxidant THP-EPQ
CAS No.:119345-01-6
Aliases:PEPQ, P-EPQ, Tetrakis(2,4-di-tert-butylphenyl)-4,4'-biphenylene diphosphonite
Molecular Formula:C68H92O4P2
Physical Properties:White to light yellow crystalline powder. Melting point: 85-95 °C. Boiling point: 854.226 °C at 760 mmHg. Flash point: 597.38 °C. Volatile matter: ≤0.5%. Ash content: ≤0.05%. Molecular weight: 1035.4 g/mol.
Uses:This product is a high-heat-resistant, high-efficiency processing stabilizer and secondary antioxidant, showing a significant synergistic effect when combined with primary antioxidants. It is suitable for polymers such as PP, PA, PU, PC, EVA, PBT and ABS, and is especially suitable for engineering plastic systems including PC, PET, PA, PBT, PS, PP, LLDPE and EVA. At a low addition level of 0.10%–0.15%, it improves color stability (anti-yellowing, anti-black-spot) and melt index stability under high-temperature melt processing. It has good compatibility with the base resin and, when used with hindered phenolic antioxidants such as 1010, significantly improves the long-term aging performance of polymers.
