Diflon K (Virgin PTFE containing an isostatic organic polymeric filler)

 

This material offers an excellent combination of properties Typical of the PTFE fluoropolymer resins:
• Service Temperature: offers excellent resistance to continuous service temperatures – working conditions from -100° C (-148°F) up to 260°C (500°F) and, for limited periods, even to higher temperatures; product’s low temperature resistance allows satisfactory performance down to –200°C (-328°F).
• Chemical resistance: offers high inertness towards nearly all known chemicals. Only attacked elemental alkali metals, chlorine trifluoride and elemental fluorine at high temperature and pressures might affect properties.
• Solvents resistance: offers insoluble properties in all solvents up to temperatures as high as 300° C (572° F). Certain highly fluorinated oils only swell and dissolve PTFE at temperatures close to the crystalline melting point.

Properties
• Improved thermal dimensional stability
• Good wear resistance
• Improved creep resistance
• Excellent electrical insulating properties
• Improved compression strength
• Low friction behaviour
• Exceptional temperature resistance
• Excellent chemical stability
• Improved surface hardness
• Suitable for food contact

Main applications
PTFE Special Compound offers excellent properties in the chemical processing, in automotive industries, in sealing application and in mechanical applications in general for bushing, sliding supports, flanged and thrust bearings, piston rings and for slide ways for machine tools. High wear and abrasion resistance and good wear compression properties are suitable for the majority of dry bearing applications against soft countersurfaces.
Special Compound has one of the lowers coefficient of friction of most reinforced PTFE materials. This make it particularly suited for start-stop applications where stick-slip must be eliminated. The tribological properties of this material also make it suitable for both bearings and wear component applications.
Special Compound has an higher temperature resistance of PTFE and is excellent for use with soft, dynamic mating surface. It has excellent physical properties and is chemically compatible with most chemicals.
