Abstract
The present invention relates to a thermoplastic resin composition, more specifically to a thermoplastic resin composition with superior extrusion and calendar formability and directly coatable without using primer because the crosslinking density can be arranged to improve the physical and chemical properties of the composition and the solubility to the solvent is increased during the coating process by including processing oil, inorganic filler, crosslinking agent and crosslinking assistant in random polypropylene resin, highly-crystalline random polypropylene resin, highly-crystalline polyolefin resin, olefin copolymer rubber and low-density polyethylene resin. This thermoplastic resin composition may be suitable for the use as surface material of the inner parts of automobiles.
