THERMOPLASTIC RESIN MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a rubber component-containing thermoplastic resin molding hardly causing deformation and crack. SOLUTION: This molding comprises a thermoplastic resin containing 5-40wt.% of a granular rubber component. The ratio b/a of an average major axis length (b) of a rubber particle 1 to an average minor axis length (a) of a rubber particle measured in a section within 30μm thickness from the surface of the molding at plural parts of the molding is <=2, the ratio of the maximum (b/a max) to the minimum (b/a min.) is in a range of 1<=(b/a max.)/(b/a min.)<=1.5 in a correlation of each section and the maximum Amax. and the minimum Amin. in correlation of the ratio of a rubber-occupied area at each section are in a range of 0<=(Amax.-A)/A<=0.2 and 0<=(A-Amin.)/A<=0.2 when the total ratio of the cross section area of the rubber particle 1 (rubber-occupied area ratio) is A%.
