NYACOL® NYAGRAPH 251 is a Expandable Graphite Flame Retardant. NYAGRAPH 251 is a natural material based on processed graphite ore. The ore is treated with sulfuric acid in what is called an intercalation process. The material is washed and neutralized to prevent corrosion of metal parts when processed by the user. Excessive shear should be avoided.
