Abstract
A resin composition which overcomes the defects of needle-like basic magnesium sulfate and has good balance among mechanical strength, molding productivity and the appearance of a molded article. The resin composition comprises (i) 100 parts by weight of a resin (component A), (ii) plate-like magnesium hydroxide having a crystal thickness (y) of 0.2 μm or less, a crystal width (x) of 3.5 to 10 μm and an aspect ratio of 20 to 100 (component B) and (iii) needle-like basic magnesium sulfate (component C), wherein the total content of the components B and C is 1 to 100 parts by weight based on 100 parts by weight of the resin, and the weight ratio of the component B to the component C is 0.1 to 0.9:0.9 to 0.1.
