Abstract

A flame-blocking system includes flame retardant foam having at least one through hole and at least one flame retardant tube passing through the through hole. Both the flame retardant foam and the flame retardant tube comprise graphite, aluminum hydroxide and ammonium phosphate in addition to a base resin. The flame-blocking system prevents flames and toxic gases generated during a fire or a similar accident from being spread through holes through which a wire, a cable or a pipe is installed across a wall of buildings or ships, which can reduce damage to life and property.
