PTFE is one of the most chemically inert materials known. It is used in many different applications and industries.
Glass fibre is the most commonly used filler in PTFE. It gives much improved compression and wear properties. The material may also be inert gas sintered to further improve creep properties and reduce porosity would be a consequent loss of tensile properties.
Glass fibre is the most commonly used filler in PTFE. It gives much improved compression and wear properties. The addition of Molybdenum Disulphide greatly improves the materials self lubrication properties particularly in dynamic sealing applications.
