Study on performance changes due to ultraviolet rays of the window frame for the vinyl chloride resin

Abstract

The polyvinyl chloride is expected to be applied to the window frame. The authors have studied deterioration of polyvinyl chloride using accelerated deterioration test by ultraviolet light. This paper prepared the four different types of specimens of additive conditions, and determined color difference, tractive characteristics, impact property, and raman spectroscopy. The results of performance evaluation were that strength was sufficient in 2000 hours accelerated deterioration test and color difference was more remarkable than strength degradation.
