Abstract

In this research, the effect of (MgO) on polyvinyl chloride (PVC) pipesexposed to sunlight was  studied. Samples  loaded with different percentages of these materials were manufactured and exposed to (UV) rays present in sunlight that causes the decomposition of PVC by means of an Aging device containing fluorescent tubes, and then conducting some mechanical and thermal tests (tensile test, hardness, internal pressure, fall weights, longitudinal rebound (thermal effect), annealing point (Vicat softining)), where the results showed that samples containing  2 % (MgO) showed the best  mechanical properties and are suitable for applications exposed to hea.
