PURPOSE: Provided is a polypropylene resin composition for non-dripping draw yarn, which contains calcium carbonate with a low specific gravity and is excellent in non-dripping property, fire-retardancy, and mechanical properties. CONSTITUTION: The polypropylene resin composition contains 100pts.wt. of a polypropylene resin, 30-200pts.wt. of the calcium carbonate with a specific gravity of less than 0.9, and additionally 5-25pts.wt. of a phosphorus-based fire retardant, 5-25pts.wt. of a bromine-based fire retardant, 2-10pts.wt. of antimony trioxide, and 30-100pts.wt. of magnesium hydroxide. |
