The major differences in properties between PTFE and PCTFE can be related to
chemical structure. The introduction of a chlorine atom, which is larger than the
fluorine atom, breaks up the very neat symmetry which is shown by PTFE and
thus ...

Characterization and Failure Analysis of Plastics
Of these materials, PTFE is capable of the lowest coefficient of friction (
approximately 0.04 to 0.1) because of the formation of transfer films. PTFE can be
used as a filler in other polymeric materials to improve lubricity (see data for
acetal, ...

How it Works: Science and Technology
The good chemical resistance of PTFE makes it the ideal material for these trays,
which are used to support silicon wafers in etching baths. The low surface energy
of the material makes it difficult to wet, so etching solution drains away with ...

Plastics Technology Handbook, Fourth Edition
With ram extrusion, the PTFE powder is fed into a cavity at one end of a heated
tube. A reciprocating ram compacts the powder and forces in into the tube. While
it is being transported down the length of the tube, the PTFE is melted and ...

Vascular Access: Principles and Practice
More recently, polyurethane has been made into vascular grafts known for
elasticity and greater compliance than either PTFE or polyethylene; these
properties have been suggested to result in less intimal hyperplasia at the
anastomotic ...
