Graphite foils and laminated sheets are the first choice for a wide range of high-temperature applications in the heat treatment industry. the size , the thickness from 0.05mm to 2mm,
Flexible Graphite Sheet/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 this as raw material, our company produces reinforced graphite sheet, spiral wound gasket, flexible graphite packing ring, and reinforced graphite gasket.
