Polypropylene resin composition with excellent flame retardancy and formability

A polypropylene resin composition comprising, based on a total weight thereof:

• a highly crystalline polypropylene resin at 20 to 50 wt % of the total weight, the highly crystalline polypropylene resin having an isotactic pentad fraction, measured according to the C13-NMR method, of 96% or more and having a melt index of 20 to 50 g/10 min;
• a highly flowable polypropylene resin at 5 to 15 wt % of the total weight and having a melt index of 500 to 1000 g/10 min;
• a glass fiber at 10 to 35 wt % of the total weight, the glass fiber having an average diameter of 5 to 15 μm and an average length of 1 to 16 mm;
• a glass wool at 1 to 5 wt % of the total weight, the glass wool having an average diameter of 1 to 6 μm and an average length of 30 to 300 μm;
• a phosphate flame retardant at 15 to 25 wt % of the total weight;
• a fluorine flame retardant aid at 0.1 to 0.4 wt % of the total weight;
• and
• a compatibilizer at 1 to 4 wt % of the total weight.
