ABSTRACT:
The present invention relates to a flame-retardant polyolefin foam comprising a polyolefinic thermoplastic resin consisting mainly of a homopolymer of .alpha.-olefin or copolymer of .alpha.-olefins having 2 to 10 carbon atoms; 2 to 10 percent by weight as bromine content, based on the weight of the foam, of a bisphenol A-based brominated epoxy resin or a crosslinked product thereof; and 0 to 25 percent by weight, based on the weight of the foam, of an inorganic filler. The foam of the present invention has superior flame retardancy and thermoformability in addition to the superior heat insulating property and shock absorbing property of the polyolefin foam, and because of these superior characteristics it is useful as an automotive interior material, etc.
