expandable graphite for flame retardant

Expandable Graphite(EG) belongs to a group of products called intumescents. The main property of intumescents is their ability to expand when heated. During the recent ten years, great progress had been achieved regarding the application of expandable graphite in flame retardant materials. Our plant has a long history to manufacture expandable graphite with an excellent quality. The carbon content is from 80% to 99.9%. The expansion volume is up to 350ml/g.This grade graphite can be used as a flame retardant, foam products, coating, plastic/metal(Al) composite board, bitumen roof sheets and anti-fire ring,etc.
