Chromium tri-oxide (CrO3) /polypropylene sheets have been prepared by twin screw extruder machine. Polypropylene (PP) is being used in producing tanks, pressure vessels, and other outer doors applications to reduce original cost. The effect of ultraviolet ray has been studied because of the tertiary carbon bonds in PP chain structure is the center of UV attack. Mechanical tests (tension, flexural, hardness, and creep) have been carried out on (CrO3/PP) with proportions (0.05%, 0.1%). The results show that, after different intervals of UV exposure (CrO3) works as stabilizer and plasticizer at the same time.
