MATERIAL DESCRIPTION
PTFE stands for PolyTetraFluoroEthylene, it is a fluorocarbon-based polymer.
The Teflon® Brand of PTFE is resin manufactured only by DuPont.
Several other manufacturers make their own brands of PTFE which can often be used as substitute material.
PTFE's mechanical properties are low compared to other plastics, and can be used over a wide temperature range of -100° F to +400° F (-73° C to 204° C).
Mechanical properties are often enhanced by adding fillers (see paragraph below).
It has excellent thermal and electrical insulation properties and a low coefficient of friction.
PTFE is very dense and cannot be processed by melting.
PTFE must be compressed and sintered to form useful shapes.
PTFE's mechanical properties can be enhanced by adding fillers.
These fillers include glass fibers, carbon, graphite, molybdenum disulphide, and bronze.
Generally, filled PTFE's maintain their excellent chemical and high temperature characteristics, while fillers improve mechanical strength, stability, and wear resistance.
Also, there are a lot of different plastics filled with PTFE.
