Description

CHLUMIAO® PEPQ / Hostanox PEPQ CAS 119345-01-6

CHLUMIAO® PEPQ, CAS 119345-01-6, is a phosphorus-based secondary antioxidant used for polymer processing stabilization. Its role is to help limit thermo-oxidative degradation and unwanted color development during processing.

PEPQ and primary antioxidants

Secondary antioxidants act on hydroperoxides, while primary antioxidants such as hindered phenols act as radical scavengers. The two roles can be combined in a stabilizer package; the suitable package depends on the polymer and processing conditions.
