Pure graphite sheets / rolls are made from natural high-purity flake graphite through chemical and high temperature treatment, molding or rolling without any adhesives. With long life and low maintenance costs, it is still of excellent sealing performance in the harsh working conditions.。
Product Applications：
It can be used as semi-finished products for manufacturing graphite packing rings and various types of gaskets.
Widely used in chemical, automobile, pump and valve industries.
Temperature：
-240～450°C Oxidizing environment
-240～3500°C Non-oxidizing environment
PH Value： 0 - 14
