Graphite Foil sheets or Grafoil sheets are cut from our production rolls and stocked for shipment. The sheets are an excellent sealing material for high temperature, high-pressure transfer of liquids, gasses, steam, chemicals, and corrosives. Graphite Foil Sheets are manufactured from high purity, high crystalline natural graphite flakes, which are processed into the continuous foil.

Shipping Information

Foil is shipped through a combination of UPS and freight depending on the order to ensure safe delivery. Additional crating cost of $35 for Meter² and $55 for 60″ x 60″ will be added to final shipping cost. Please contact us directly for a custom shipping quote or place your order and a representative will contact you to confirm shipping cost before processing your order.
