    摘要: The present invention is an unsaturated polyester resin composition comprising an unsaturated polyester (a), a monomer (b) having one polymerizable carbon-carbon double bond, a monomer (c) having two or more of (meth)acrylate groups, a filler (d) having high thermal conductivity, a glass fiber (e), a low profile additive (f), a curing agent (g), and a polymerization inhibitor (h), wherein the ratio by weight of the ingredient (b) to the ingredient (c) is from 50:50 to 75:25 and the unsaturated polyester resin composition comprises 400 to 1400 parts by weight of the ingredient (d) based on the total 100 parts by weight of the ingredients (a), (b), and (c). This unsaturated polyester resin composition has excellent curing properties without losing storage stability which can be used to provide a cured product having a low mold shrinkage ratio and high thermal conductivity.

    摘要: Provided is an unsaturated polyester resin composition comprising 100 parts by mass of an unsaturated polyester resin (a) 400 to 1,000 parts by mass of a mixture of an inorganic filler (b) having a thermal conductivity coefficient of 20 W/m·K or more and aluminum hydroxide (c); 20 to 300 parts by mass of a glass fiber (d) having a fiber length of 1.5 mm or less; and 15 to 50 parts by mass of a low profile additive (e), the inorganic filler (b) and the aluminum hydroxide (c) being mixed at a mass ratio of 80:20 to 20:80, in which the unsaturated polyester resin composition further includes an alkyl peroxyalkylate-based curing agent (f) represented by the following formula (1):

    wherein R represents an alkyl group; and R' represents an alkyl group having 3 or more carbon atoms, and a polymerization inhibitor (g). The unsaturated polyester resin composition yields a cured product having a low shrinkage ratio, a low linear expansion coefficient, and a high thermal conductivity coefficient, and is excellent in in-mold flowability and curability.
