Polytetrafluoroethylene - Wikipedia
网页Because of its extreme non-reactivity and high temperature rating, PTFE is often used as the liner in hose assemblies, expansion joints, and in industrial pipe lines, particularly in applications using acids, alkalis, or other chemicals. Its frictionless qualities allow improved flow of highly viscous liquids, and for uses in applications such ...

Teflon PTFE - CRP US
网页Teflon™ PTFE fluoropolymer resins are tetrafluoroethylene polymers, usually fabricated into parts by cold-forming and sintering techniques. Teflon™ PTFE fluoropolymer resins have a continuous service temperature of 260 °C (500 °F). Much higher temperatures can be satisfactorily sustained for shorter exposures.
Effects of High and Low Temperatures on PTFE Performance
网页2021年4月1日 · With an operational temperature range between -300 degrees Fahrenheit and +450 degrees Fahrenheit, PTFE may be able to maintain structural integrity and function at extreme temperatures, but performance can still be greatly affected.
网页PTFE mechanical properties are low compared to other engineering plastics, but its integrity is maintained over a wide temperature range - from -400 to 500°F (-240 to 260°C). Mechanical properties can be improved by the addition of fillers such as glass fiber, carbon, graphite, molybdenum disulfide and bronze.
