Fire-retardant tablet, and fire-retarding method, fire-retardant polymer composition and molded article employing the same |
摘要 |
Fire retardant tablet is provided which is produced by tableting a fire retardant mixture containing heat-expandable graphite (A), and a water-soluble fire retardant synergist (B) or one containing additionally water-insoluble fire-retardant synergist (C). A method for fire retardation, a fire-retardant polymer composition, and a molded article of a fire-retardant resin by use of the fire retardant tablet are also provided. In the production of a fire retarding polymer composition containing heat-expandable graphite, the crushing of the heat-expandable graphite under melt-shearing is minimized.
