Material Overview


What is 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.

At Fluorocarbon

We manufacture PTFE semi-finished products including rod, tube and sheet by extrusion and compression moulding. In addition to this we machine and mould finished components for a range of industries including Aerospace, Semi-conductor, Petrochemical and Oil and Gas. We ensure the highest quality materials by mechanical property testing. All our materials are tested on site to International Standards so we can maintain a consistent quality product without impacting on lead times.
