FIVE YEARS OUTDOOR EXPOSURE TEST OF RIGID PVC PRODUCTS FOR WINDOW

Abstract

The results of the mechanical properties and aesthetics of rigid PVC products for window with high thermal insulation performance are reported after five years of outdoor exposure test. By the fifth year of exposure, the tensile modulus had increased and a change in color difference due to staining was observed. However, there was no difference in mechanical and aesthetic properties between the lead-based stabilizers used so far and the recently switched calcium-zinc stabilizers.
