Hostanox™ P-EPQ™ mini pills
Hostanox P-EPQ mini pills is a highly efficient phosphorus based secondary antioxidant, which reduces the thermo-oxidative degradation of polymers and the development of undesired color (yellowing) during processing. The main advantages of Hostanox P-EPQ mini pills are its high thermal stability and high solubility in polymeric materials as well as its broad compatibility in coating polymers.

Hostanox P-EPQ mini pills is recommended especially for the applications where polymers and/or binders are cured at elevated temperature and need thermo-stabilization, e.g. powder coatings, coil coatings and specific solventborne coatings (automotive for ex.).
Hostanox P-EPQ mini pills is suitable for most kinds of thermoplastic polymers. It is recommended especially for the stabilization of polyolefins (LLDPE, HDPE, PP), ABS, PS, polybutylene, PBT, PC, PA, thermoplastic polyester, nitrile barrier resins, etc.
