Product Description
GLASS / GRAPHITE / CARBON / BRONZE FILLED BLACK PTFE TUBE
Improved material properties can be achieved by the addition of selected fillers. These fillers extend performance characteristics
and allow for wider application - particularly in demanding thermal stability and load support situations.
In addition, the frictional and thermal properties of PTFE remain generally unaffected.
The glassfilled PTFE grades, GL25 and GLI5, show improved wear and creep resistance compared with unfilled PTFE, while the chemical resistance is virtually unaffected. B40, a bronze filled compound,
has a high thermal conductivity resulting in excellent bearing properties at high speeds,
particularly where unhardened shafts are used.
Key Features:
· Extremely good chemical resistance against virtually all media
· Wide temperature range (-260ºC to +250ºC)
· Good sliding properties
· Improved dimensional stability
· Improved creep resistance
· Very good electrical insulation properties
Glass Fibre (Filled PTFE)
· Oxidation and acid resistance
· Dimensional stability
· Good electrical properties
