Dalau Dalcon 020 Virgin PTFE, Carbon (Anti-Static)
Categories: Polymer; Thermoplastic; Fluoropolymer; Polytetrafluoroethylene (PTFE)

Material Notes: Applications & Industries:
General: The static and dynamic friction coefficient are numerically equal, consequently no ’Stick Slip’ occurs.
Electrical: Ideal for Anti - Static Applications; Anti - Static Hose Linings; and Anti - Static Diaphragms.

CHEMICAL RESISTANCE: The strength of the carbon - fluorine bond and the shielding of the carbon chains by the fluorine atoms result in a chemical inertness which is virtually universal, except alkali metals, fluorine under certain conditions, and some fluorine compounds at elevated temperatures. Some Fluorinated Hydrocarbons (refrigerants) cause reversible swelling i.e. Telrafluorodichloroethane Frigen 21, giving a 9.6% weight increase. For specific data on chemical resistance of this material we have a computer database with all the information covering over 90% of all known chemicals.
