Abstract
The article reported the analysis of the influence factors for the oxygen permeability of oxygen barrier pipes,and these factors include the ethylene content of ethylene-vinyl alcohol copolymer (EVOH),the wall thickness of oxygen barrier layer and the processing temperatures.The results indicated that the lower the ethylene content of EVOH,the better the oxygen barrier performance.There was a correlation between the wall thickness of oxygen barrier layer and EVOH brand.Generally,the thickness of barrier oxygen layer thickness was in the range of 0.08～0.10 mm.There was no significant influence observed from the processing temperature of EVOH layer on the oxygen barrier performance of the pipes.关键词
