STUDY OF TALC FILLED POLYPROPYLENE- A CONCEPT FOR IMPROVING MECHANICAL PROPERTIES OF POLYPROPYLENE Shri Kant

Talc is a important filler for polypropylene (PP) and Non halogen flame retardants (ammonium polyphosphate) is used with PP. It does not generate toxic gases and corrosive smokes during combustion. The addition of flame retardants will lower the flammability of PP. Talc improves the mechanical properties (stiffness, flexural strength, modulus etc) and heat deflection temperature. Two types of mechanical testing have been done to determine the mechanical properties, which are flexural test and tensile test.In this study, the improvement of mechanical properties have shown with increasing suitable percentage (by weight) of talc for a new applications
