PTFE Coated Sewing Threads

Our glass threads are manufactured from 'E' continuous filament yarns and are totally encapsulated in PTFE. This enhances the resistance to contaminate build up and also helps to repel attacks from most acids and alkalis.

Our PTFE coating is smooth and consistent which allows for maximum performance of the thread and minimises the possibility of kink, strip back and breakage that can be experienced using very high temperature yarns.


Silver plated copper2, 3, 4, 6 and 8 core
Nickel plated copper2, 3, 4, 6 and 8 core
Plain soft copper2, 3, 4, 6 and 8 core

These cables are available in fibre glass and PTFE versions. They can be screened and/or metal overbraided. We can also produce cables to your own specifications.

High Temperature Power Cables

We produce a range of cables for use where there are elevated temperatures. They are produced from Nickel Plated Copper or Pure Nickel conductors. We can offer single and multi-core cables within this range. For further information please request our data sheets for these types of cables.


We also produce a range of PTFE equipment wires in single and multi core versions in silver plated copper and nickel plated copper. Screened and unscreened constructions are available.
