GRAPHITE/CARBON INFO ABOUT GRAPHITE WATER JET CUTTING QUERY FORM
CHEMICAL RESISTANCE TYPICAL COMPONENTS

Graphite, the core material for manufacturing graphite seals, is crystalline, overlapping, natural graphite. Thermal decomposition of these bonds results in loose flakes. These flakes are then compressed into a film whereby the graphite particles realign themselves. Through this alignment, properties with large directional dependency result - such as thermal and electrical conductivity.
As graphite has metallic lustre and a significant thermal and electrical conductivity, it may be called a metal-carbon modification.

This is how one may define graphite in general terms. But what advantages does graphite offer over other materials?

Advantages:

  • stable in temperatures from -220°C up to +550°C (in pure oxygen up to +300°C)
  • high chemical resistance against almost all media (see chemical resistance list)
  • non-combustible
  • good mechanical properties over the entire temperature range
  • very flexible
  • resistant to aging, does not become brittle
  • safe for human health
  • resistant to radiation
  • large range between the minimum and maximum pressure
  • universal use
Grades: nuclear grade: 99.8%, chemical grade (or also industrial grade) 98%.
