Evaluation on anti⁃yellowing enhancement of PE⁃HD using a low yellowing compound antioxidant system

doi:10.19491/j.issn.1001-9278.2022.01.011

Abstract

Abstract:

The enhancement effect of BASF low yellowing compound antioxidant system A on the anti?yellowing of PE?HD was evaluated， and their anti?yellowing， anti?oxygen and processing stability were investigated intensively. The results indicated that BASF antioxidant system A had a better anti?yellowing effect than normal antioxidant systems. After using the recommended dosage and double dosage， the yellowing degree of the product was low， and its yellow index changed little after multiple extrusion. However， its anti?oxidation effect was poor. The problem of yellowing can be resolved through reducing the content of antioxidant 1010.

Key words: high?density polyethylene, low yellowing, antioxidant
