Graphite sheets

Expanded graphite is used in high temperatures and has a very good level of chemical resistance. It is a soft material that has a better compression rate than gaskets made out of fiber mixtures, thus assuring a higher level of tightness.

Some of the extraordinary properties of the expanded graphite in sealing processes:

• The lack of any volatile constituents, thus guaranteeing the same initial volume and physical-mechanical properties of the sealing elements
• Resistance to cryogenic temperatures of up to 550⁰C in the air and 3000⁰C in inert atmosphere
• Fire protection
• A high degree of conductibility, with very good effects on heat dissipation in dynamic sealings
• Exceptional resistance to most aggressive corrosive environments (pH 0-14)
• Elastic recovery up to 10% of initial thickness
• Inert from the chemical point of view
• No risk associated with food
• Completely harmless to people’s health

Graphite sheets are manufactured in various ways, with or without insertion:

Types of insertions:

• SR = without insertion
• RI = insertion with plane stainless steel 316L(50μ)
• RN = double insertion of nickel (13μ)
• PI = insertion with perforated stainless steel 316L(100μ)
• GI = insertion with stainless steel net 316L

Standard available thickness: 0.2 mm; 0.5 mm; 0.8 mm, 1 mm; 1.5 mm; 2 mm; 3 mm; 5 mm. Upon request, we can manufacture products with non-standard thickness.

Maximum width: 1000 mm
