POLYPROPYLENE MOLDING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a polypropylene molding material excellent in flame retardance, heat resistance and color change resistance to heat and light at a low cost. SOLUTION: This polypropylene molding material comprises a highly crystalline and homogeneous polypropylene. Heat resistance is enhanced without compounding talc. Consequently, the absorption of a flame retardant by talc can be prevented and the flame retardance can be increased without compounding the flame retardant in large quantities and lowering of color change resistance to heat and light caused by compounding the flame retardant can be prevented.
