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.
