In general, there are three basic types of gaskets, namely metal, non-metal and half metal. Metal gaskets made of copper, aluminum or brass. Non-metal gaskets are usually made from asbestos, rubber, paper, flax, leather, cork and ceramics. Usually as sealing between nonmetal gasket components used asbestos, rubber and paper base material. For semi metal materials are usually a combination of metal and non-metal materials.
In more detail, the gasket making materials are: Rubber Gaskets: There are many types of gaskets that use rubber sheet or rubber sheets, such as neoprene, nitrile, fluorocarbon, red rubber, aflas and silicone.
Viton Gaskets: Viton gaskets are widely used for systems where there are chemicals that are acidic or basic, hydrocarbons and oils, both vegetable and animal.
PTFE (Polytetrafluoroethylene) Material: PTFE Gaske or Teflon gaskets are the most widely known gaskets, because they are multi-functional. Teflon has good resistance to various chemicals, including hydrogen peroxide.
Graphite Gaskets: Graphite is flexible resistant to heat. In addition, this type of gasket is also resistant to very acidic and alkaline conditions.
EPDM (Ethylene Diene Monomer Propylene (M-class) rubber) Material: Gaskets with EPDM material are resistant to ozone, Ultra Violet rays, natural oils and various types of chemicals.
