Product description

Description

Flexible graphite sheet, normally we call it "Expanded Graphite Sheet", it is made of nature graphite flake. Expanded graphite rolls is chemically treated graphite interaction compound. This interaction compound is then rapidly heated to decomposition.the result is a rapid expansion of the particle size. Then they are formed into graphite sheets by rolling.

Application

Made for packing rings and various kinds of gaskets
Cut into strip for filler of spiral wound gasket
Used widely in chemical, automotive and pump, valve industries

Feature: 

1.High and low temperature resistance. The physical properties of flexible graphite have little changes in the non oxidizing ( from - 270 ℃ to 3650℃),it can be used in the air up to 450 ℃.

2.Excellent corrosion resistance.Flexible graphite can be resist almost all of inorganic and organic medium except Water, sulfuric acid, nitric acid and high temperature dichromate, potassium permanganate, ferric chloride and other strong oxidizing medium.

3.Good self-lubrication.Flexible graphite, like natural graphite, the interlayer has good wearing resistance, low friction coefficient.

4.When the shaft or shaft sleeve appear radial circular runout problems , it can be sealed well with sufficient floating performance even if the graphite cracks.

5.It is a kind of economical and practical products to achieve good sealing effect with ordinary flange surface requirements and small pre-tightening force.
