Abstract

Although polypropylene (PPHP) has become one of the largest and fastest growing polymeric materials, some disadvantages in its properties, like poor stability to Ultra-Violet (UV) radiation, stiffness may impede its growth in commercial use. Hence to improve its stiffness talc addition is suggested. The purpose of our present investigation is to examine the effects of talc (inorganic filler) and low dose of UV radiation on mechanical and structural properties of PPHP and PPCP/talc composites. The samples were characterized by X-ray diffraction, FTIR spectroscopy, tensile testing and hardness tester. The effects on mechanical and structural properties of modified PPCP i.e. talc filled polypropylene (TFPP) before and after UV radiation exposure of composite is discussed.
