The influence of masterbatches of fillers and stabilizers on polyethylene’s thermostability

摘要

The article presents the influence of joint and separate introduction of fillers (ADDITIVE 13169, TALC MB, EFPE 1001, VC PE 175) and stabilizers (RA10) masterbatches on the thermal aging of polyethylene’s composites. It was estimated the thermal stability of polyethylene compositions by determining dynamics change of strength properties du ring thermal aging. The ac tivation energy of thermal oxidative degradation of polyethylene compositions was calculated. The content of carbonyl groups in the IR spectra was determined. Compositions with high thermal stability containing mas-terbatches chalk (VC PE 175) and talc (TALC MB) and masterbatch stabilizer PA10 were developed.
