25% Carbon (75% Virgin PTFE + 25% Carbon)

 

 

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 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.
• 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.

 

Carbon Compound enhances some characteristics of virgin PTFE such as wear and compression strength, deformation under load, cold creep, thermal conductivity and dimensional stability.

 

Properties
• Improved thermal dimensional stability
• Excellent chemical stability
• Improved creep resistance
• Good thermal and electrical conductivity
• Improved compression strength
• Good cold flow reduction
• Excellent wear resistance
• Excellent resistance to abrasion
• Exceptional temperature resistance
• Improved surface hardness

 

PTFE Carbon Compound offers excellent properties in the chemical processing, in automotive industries, in sealing application, in water application (one of the lowest wear rates in fresh water) and in mechanical applications, in general for bushing, sliding pads, and for slide ways for machine tools.
High wear resistance, abrasion resistance and good wear compression properties are suitable for the majority of dry bearing applications against hard counter-surfaces.
Carbon Compound is widely used in seal applications where high wear resistance is required under high compression, e.g., piston tings for dry compressor, bearings, grooved mechanical support.
PTFE Carbon Compound is recommended for dry and poorly lubricated applications, suitable in water and steam service, also when a fast dissipation of electric charge is needed.
