PURPOSE: Provided is a thermoplastic polyurethane resin composition which produces continuously foamed material compared with existing technology so that artificial leather with high coefficient of expansion, low density, and light weight is provided. The leather material has not only excellent insulating effect due to the characteristics of thermoplastic polyurethane but also does not discharge environmental hormone like dioxin. The composition is used in a general open type rolling mill, enhances productivity and reduces cost. CONSTITUTION: The thermoplastic polyurethane resin composition comprises: 65-95wt.% of thermoplastic polyurethane resin; 1.0-6.5wt.% of softener; 0.5-2.0wt.% of stabilizer; 1.5-6.5wt.% of foaming agent; 3.0-10.0wt.% of additive for ABS resin or rubber and 4.0-10 wt.% of dye. Additionally, 1.0-50wt.% of filler (based on the total weight of the composition) is mixed to the composition. The softener is selected from a group of butylbenzyl phthalate, dioctyl adipate and triethyl citrate.
