Frequently Asked Questions
How does 25% glass filled PTFE differ from standard PTFE rod?
The 25% glass filled grade contains glass fibres uniformly dispersed throughout the PTFE, significantly increasing its mechanical strength, rigidity and resistance to deformation compared with standard virgin PTFE. While it retains many of the low friction and chemical resistance properties of PTFE, the glass reinforcement makes it better suited to higher load and wear applications.
Can this glass filled PTFE rod be machined with standard workshop tools?
Yes, the rod can be machined using conventional turning, milling and drilling equipment commonly found in engineering workshops. Sharp tools and appropriate cutting conditions are recommended to achieve a good surface finish, and the improved rigidity of the glass filled material generally makes it easier to hold tolerances than unfilled PTFE.
Is 25% glass filled PTFE suitable for use with aggressive chemicals and solvents?
Glass filled PTFE retains the excellent chemical resistance characteristic of PTFE and is compatible with a wide variety of acids, alkalis, solvents and process chemicals. As with any application, it is advisable to check specific media and operating conditions to ensure long-term suitability, particularly at elevated temperatures and pressures.
