Applications of PTFE blocks
PTFE blocks are typically used for chemical-contact components, valve seats, gaskets, pump parts, bearing pads and low-friction surfaces in process, laboratory and electrical insulation applications. Chosen for broad chemical compatibility, low coefficient of friction and stable performance across wide temperatures, PTFE (Teflon) is often specified where sticking, corrosion or dielectric properties are critical. The material can be less suitable where high mechanical load, sustained compressive stress or abrasive wear occur, since creep and cold-flow may lead to dimensional change and faster wear compared with filled polymers or metals.
