Frequently Asked Questions

Q: What lengths are available?
A: This size range is supplied in 1000mm lengths. Length tolerance is -1/+3mm.

Q: Can I order custom sizes?
A: No — this product is supplied in the standard sizes listed on this page.

Q: What colour is glass filled PTFE?
A: Off-white to light cream. Unlike virgin PTFE it has a slightly matt, speckled surface from the glass fibres.

Q: Is this material suitable for outdoor use?
A: Yes, glass filled PTFE is resistant to UV and weathering.

Q: How does glass filled PTFE compare to standard PTFE?
A: The glass filling (typically 25%) greatly improves creep resistance, wear resistance and dimensional stability, with slightly higher friction. It keeps PTFE's chemical resistance and wide service temperature range.

Q: What industries use glass filled PTFE?
A: Chemical processing, pumps and valves, aerospace and general engineering, mainly for seals, valve seats, bearings and wear parts.
