Effects on the Properties of Polyethylene Film Aging by Different Methods

Abstract:

Aging of plastics occurs in use, it makes the performance degrade, and losing use value finally. In order to compare ultraviolet aging with thermal aging, we carry out a pilot study on the performance changes of PE film. The results demonstrated that the tensile property became lower under two aging methods, the tensile property during the thermal aging decreased by 6.07% but it was 15.08% in the ultraviolet aging at 120h, obviously the effects of the ultraviolet aging on the tensile strength were more significant, it declined faster. The air permeability curves were on the rise under the two aging methods, the results demonstrated that the effect of the ultraviolet aging on the air permeability rose slightly more than the thermal aging. The moisture permeability curves decreased firstly and then increased, but the values of the ultraviolet aging were higher.
