WebSIGRAFLEX flexible graphite is manufactured without the use of adhesives and binders. The material does not age or become brittle. Only high-purity natural graphite flakes are used as raw material, thus also minimizing contamination. Its high purity has a significant positive effect on the corrosive resistance. Graphite occurs in metamorphic rocks as a result of the reduction of sedimentary carbon compounds during metamorphism. It also occurs in igneous rocks and in meteorites. Minerals associated with graphite include quartz, calcite, micas and tourmaline. The principal export sources of mined graphite are in order of tonnage: China, Mexico, Canada, Brazil, and Madagascar.
