Moulded & Machined Finished Products
 It is often more efficient to use moulded
 semi-finished products to avoid excessive
 machining of relatively expensive materials
 and also to reduce machining labour and
 time.
 
 The tooling costs are generally very low.

 PTFE is chemically inert & unaffected by all known chemicals except molten or dissolved alkali metals-Sodium, Potassium, Rubidium, Cesium, Francium &
Fluorine Gas.
certain fluorine compounds & complexes at elevated temperatures.
Filled PTFE has interior chemical resistance because of the presence of the
particular filler.
