25% Glass (75% Virgin PTFE + 25% Glass Fibres)

 

 

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 up (-148°F) to 250°C (482°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.
Glass fibres is chemically inert with the exception of its reactivity with hydrofluoric acid and strong bases.
• 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
• Excellent chemical stability
• Improved creep resistance
• Excellent electrical insulating properties
• Improved compression strength
• Reduced friction & wear; Low friction behaviour
• Exceptional temperature resistance
• Improved surface hardness

Main applications
PTFE Glass Compound offers excellent properties in the chemical processing, in automotive industries, in sealing application and in mechanical applications in general for bushing, sliding pads, 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 hard counter-surfaces.
PTFE Glass Compound is commonly used filler for dynamic seal applications where both rotating and alternating movements are involved, pneumatic, hydraulic and mechanical parts, valve seats, gaskets, pneumatic, compressors, appliances, insulators hydraulic and mechanical parts.
