IG - 001 Flexible Graphite Foil

Selection of high quality scales expanded graphite, the heat expansion and a series of rolling process. High and low temperature resistance, corrosion resistance, anti-aging, self-lubricating, compressibility, resilience and good sealing performance, is the foundation of manufacturing various graphite packing material.Expanded graphite coil without binder and filler, so a high purity, good corrosion resistance, radiation resistance, high/low temperature resistance, good compression resilience, and have self lubrication and impermeability is suitable for sealing of the low pressure. Graphite can coil and sheet metal composite with various forms of graphite composite board.

Main application: production of graphite packing ring, graphite strip, sealing gasket, composite plate, cylinder pad, paste in all kinds of metal surface, improve the sealing performance, etc.

Flexible Graphite Foil characteristics:

1. Has excellent heat resistance and cold resistance. Flexible graphite from ultra-low temperature - 270 degrees to 3650 degrees (in the non oxidizing gas of high) temperature, its physical properties have little change, in the air can also be used to around 450 degrees;

2. Have excellent resistance to chemical corrosion. In addition to flexible graphite in aqua regia, concentrated nitric acid, sulfuric acid and high temperature dichromate, potassium permanganate, ferric chloride and other strong oxidizing medium have corrosion, almost all of inorganic and organic medium corrosion resistance;

3. Good self-lubrication. Flexible graphite, like natural graphite, interlayer under the action of external force, prone to slip, thus has lubricity, has good wearing resistance, small friction coefficient;

4. High resilient rate. When the shaft or shaft sleeve by manufacture, installation, eccentric radial round beats, with sufficient floating performance, even if the crack of graphite, can very good seal, so that post close tightly, to prevent leakage.

5. Expanded graphite gaskets to the flange surface requirement is not high, the smaller the pre-tightening force can achieve sealing effect, cutting easy gasket is a more economical and practical.

Product application:

1. It is a graphite packing ring material

2. Can and sheet metal composite graphite composite board cutting into various shapes of sealing gasket

3. Directly used to produce all kinds of low pressure washers or processed into thick plate do after high temperature heat insulation plate
