Conductive Graphite, Graphene, and Carbon

Compressible Graphite Sheets

Reinforced Compressible Graphite Sheets

A stainless steel insert makes this material stronger than standard compressible graphite.

Ultra-Conductive Graphene Sheets

This highly conductive graphene material is often used in electronic devices, such as cell phones, laptop computers, digital cameras, and LEDs.

Ultra-Conductive Graphene on Silicon Wafers

Already set on a silicon wafer, these highly conductive graphene sheets are ready for use in semiconductors, advanced sensors, and electrodes.

Ultra-Conductive Graphene on Copper Foil

Grown by chemical vapor deposition (CVD) on copper foil, this highly conductive graphene material can be transferred on to glass, silicone, and plastic film for use in proton exchange membranes, flexible electronics, and advanced sensors and electrodes.

Conductive Graphite Sheets and Bars

Ultra-Fine-Grain Conductive Graphite Sheets

This graphite is denser and slightly stronger than standard conductive graphite because it has a smaller grain.

Gaskets

High-Temperature High-Pressure
Graphite Gasket Material

This material withstands temperatures up to 850° F and pressure up to 2,000 psi.

High-Temperature High-Pressure
Fire-Rated Graphite Gasket Material

Made of American Bureau of Shipping Fire Safe approved graphite material, these sheets withstand temperatures up to 650° F and pressure up to 2,000 psi.

High-Temperature Extreme-Pressure
Graphite Gasket Material

Able to withstand pressure up to 10,000 psi, this is our highest pressure-rated gasket material. It handles temperatures up to 850° F.

Gasket Material Assortments

Each assortment includes a variety of materials to meet your gasketing needs.

Made-to-Order High-Temperature Graphite Gaskets

Also known as Hochdruck, these graphite gaskets have stainless steel layers for added strength in hot environments.
