PTFE
PTFE is made up of Fluorine and Carbon atoms. The Fluorine atoms are just the right size to form a helical shield around the carbon atoms. This stops any chemical attack on the carbon atoms because nothing can get close enough. Fluorine is an extremely reactive element and by this virtue the chemical bond between it and carbon is one of the strongest bonds known in organic chemistry.
This is why only under extreme conditions can PTFE be attacked. The forces between polymer chains are extremely small which gives PTFE its excellent low coefficient of friction.
Our proprietary FL103 material (glass fibre filled PTFE) has AIRBUS approval, making Fluorocarbon the only UK supplier approved to supply this material in accordance with BS6564-3.
Using our proprietary in-house manufacturing process, we are able to produce low-stress PTFE rods in lengths up to 2000 mm (78”), specifically designed for high-precision machining within exceptionally tight tolerance bands. This capability is unique to Fluorocarbon, with no other manufacturer worldwide able to offer the same combination of length, stability, and precision.
