Our grade GT-FLON is insensitive to solvents, organics which usually corrode traditional “phenolic resin” impregnated materials. Outperform in pharmaceutical batch processes, agro chemical, stainless steel pickling baths. Our Silicon carbide (SiC) offers an excellent alternative materials to metals, super-alloys for very corrosive applications (chlorine and bromine compounds) and high purity processes. Unlike metals, corrosion resistance is seldom affected by contaminants (chlorides, fluorides,...). Graphite PTFE Micrography of impregnated graphite structure ( x1000) Impregnation of...
