AFT Fluorotec AF103 Glass Filled PTFE

AFT Fluorotec AF103 Glass Filled PTFE 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 and gas permeability. There would be a consequent loss of tensile properties.
