Chemical Resistant PTFE Films

PTFE (PolyTetraFluoroEthylene) is a fluorocarbon-based polymer that exhibits astonishing chemical resistance and ultra-high-purity. Self-lubricating and with a low friction coefficient, PTFE is suited for the manufacture of high-temperature seals, insulators, and bearings used in semiconductor, aerospace, and chemical processing industries. PTFE's mechanical properties are low compared to other plastics, and can be used over a wide temperature range of -73°C to 204°C. Mechanical properties are often enhanced by adding fillers. 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.

Features:

• Lowest coefficient of friction of any known material
• PTFE operates up to 260°C
• Tremendous chemical resistance
• PTFE is an excellent insulator
• Limitations: PTFE has low compressive & tensile strength
