Flexible Graphite ---Graphite Foil/Sheet

This unique material is based on natural graphite flakes with well crystalline structures, which is through chemical treatment, expanding under high temperature and then rolling. Properties are highly anisotropic, particularly in respect to electrical and thermal conductivity. Graphite foils and sheets are available in different thicknesses. Graphite sheets are manufactured unreinforced, impregnated or reinforced.

NOTE:

°§ The above product properties are available when Bulk Density is 1.0 (63 ).
°§ Except above Grades, we can manufacture specially as per your requirements below:
°° °™ Graphite sheet with nuclear class-special material for nuclear power
°° °™ Non-oxidizing graphite sheet-much higher working temperature
°° °™ Corrosion inhibitor graphite sheet-effective avoid the corrosion to spot on the sealing surface,
°° °° the sealing is more reliable.

Typical types of Graphite Sheets
°§ Graphite Sheets Microperforated/Other unreinforced Graphite Sheets
°° The products of Graphite Sheets Microperforated are punched small holes in Graphite Sheets,
°° which widely used in furnace to release gas. A wide range of normal Graphite Sheets unreinforced
°° and Graphite Sheets Microperforated with specifications of 1.0-3.0x1,500x1,500mm and
°° 1.0-3.0x1,000x1,000mm are available.
°§ Reinforced Graphite sheets
°° The product is formed by pressing mechanically or sticking from flexible graphite sheets together
°° with metal plate. It has excellent sealing property for microscopic surface irregularities and
°° strong compensation capacity for uneven sealing surface. It also has good compressibility,
°° good resilience, small stress relaxation and long working life. It is commonly used for making
°° cylinder gaskets of engines and punching into all kinds of sealing gaskets. Both sizes
°° of 1.0-3.0x1,500x1,500mm and 1.0-3.0x1,000x1,000mm are available as follows:
