Applications
Antioxidant P-EPQ is high efficiency secondary Antioxidant with high temperature resistant.
Suitable to PP, PA, PU, PC, EVA, PBT, ABS and other polymers, especially for engineering plastics PC, PET, PA, PBT, PS, PP, PE-LLD, EVA systems.
It can improve the color stability (anti-yellow, anti-black point) under high temperature melting process, and have broad compatibility with matrix resin.
It has good synergistic effects with primary Antioxidant like Antioxidant 1010, and improve the long-term aging performance of polymers.
The dosage is low, 0.10 ~ 0.15%, will show good effect.
