Flexible Graphite Roll is made from expanding Expandable Graphite under high temperature and then rolling. It has the characteristics of high temperature resistance, corrosion resistance and good elasticity.
With Flexible Graphite Roll as raw material, our company produces reinforced graphite sheet, spiral wound gasket, flexible graphite packing ring, and reinforced graphite gasket.
