Abstract:
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.
