ABSTRACT:
A novel fire-retardant polymer composition is provided which comprises 100 parts by weight of a polymer such as polyolefins and polystyrenes, 1-30 parts by weight of an oxide or a complex oxide of metals such as antimony, boron, and molybdenum, and 1-30 parts by weight of heat-expandable graphite. The fire-retardant polymer composition emits less amounts of smoke and corrosive gas on burning with the characteristics of the polymer material kept unimpaired.
