The Weathering of Plastics Materials in the Tropics. 4. Polysulphone.

Abstract

The report describes the effect of long term weathering on polysulphone. Both unpigmented samples and samples containing carbon black were exposed for up to 4 years at two tropical and one temperate site. Visual appearance, weight, tensile and flexural strength and electrical properties were recorded and used to monitor the effects of weathering on polysulphone. Unpigmented samples were found to embrittle rapidly while carbon black filled samples showed no loss of flexural strength and losses of ductility smaller than those observed with the natural material.
