<p><P>PROBLEM TO BE SOLVED: To provide a thermoplastic resin plate-like molded article which reduces generation of mutual pushing up, gapping, etc. of the plate-like molded articles due to expansion and contraction by temperature difference between winter and summer seasons. <P>SOLUTION: The thermoplastic resin plate-like molded article is formed by blending 5 to 40% in volume ratio of a filler into the thermoplastic resin, able to form a plain surface by combining in numbers, and is characterized by having linear thermal expansion coefficient of 2.0×10<SP>-5</SP>to 8.5×10<SP>-5</SP>after profile extrusion molding; wherein the coefficient is obtained by measuring dimensions under 0°C and under 40°C atmospheres, dividing the difference between each dimension by the dimension under 0°C and further dividing it by the temperature difference (40). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
