  • Unsaturated polyester resin composition, molded article thereof, and lamp reflector
    Patent number: 9447944
    Abstract: The present invention provides an unsaturated polyester resin composition including an unsaturated polyester, a crosslinking agent, an inorganic filling material, a hollow filler, and a fibrous reinforcing material, in which the hollow filler has a content ratio of a hollow filler having a particle diameter of 30 ?m or less of 80 vol % or more with respect to the total volume of the hollow filler, and in which the content of the hollow filler in the unsaturated polyester resin composition is from 15 to 24 mass %. The unsaturated polyester resin composition can provide a molded article having both reduced specific gravity and improved self-tapping strength while maintaining the conventional characteristics (surface smoothness, heat resistance, mechanical strength, dimensional accuracy, and moldability).
