Abstract

PURPOSE: A resin composition that is prepared by adding an α-alumina powder with a specific particle shape to a resin, thus having high moldability, mechanical strength and moisture-absorbing resistance.
CONSTITUTION: To a resin as rubber, epoxy resin or polyethylene (A), is incorporated (B) over 5, preferably 15W50 vol% of an α-alumina powder with a weight-based average diameter of 0.5W50 microns and a shape factor of 1W1.4, which is prepared by adding α-alumina seed crystals with the sizes of less than 100 microns to an alumina hydrate so that WR [the total weight of the alumina hydrate calculated as the trihydrate in g./As [the total surface area of α-alumina seed crystals in cm2] becomes less than 0.05 g/cm2 and treating the mixture with moisture heat at 150W500 kg/cm2 and 370W500°C for 2W10 hr to grow the seed crystals, then crushing them for 20W200 min.
