Specification of Carbon Teflon
TEFLONPolyTetraFluoroEthylene is a fluorocarbon based polymer and is usually abbreviated as PTFE. The Teflon® brand from PTFE is only produced by DuPont. Some other manufacturers make their own PTFE brand which can often be used as a substitute material. This fluoroplastic family offers high chemical resistance, low and high temperature capabilities, weathering resistance, low friction, electrical and thermal insulation, and "slippery". (See also Teflon® PTFE and Teflon® FEP & PFA Specifications) PTFE mechanical properties are low compared to other plastics, but their properties remain at a useful level over a wide temperature range between -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 melted - it must be compressed and sintered to form a useful shape.
