Flomasta PTFE Liquid 50g

Product Information

Its extremely high bulk resistivity makes it an ideal material for fabricating long-life electrets, the electrostatic analogues of permanent magnets. 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 as brake hoses. Polytetrafluoroethylene ( PTFE) is a synthetic fluoropolymer of tetrafluoroethylene and is a PFAS that has numerous applications. The commonly known brand name of PTFE-based composition is Teflon by Chemours, [3] a spin-off from DuPont, which originally discovered the compound in 1938.

Processing PTFE can be difficult and expensive, because the high melting temperature, 327°C (621°F), is above the initial decomposition temperature, 200°C (392°F). [33] Even when molten, PTFE does not flow due to its exceedingly high melt-viscosity. [34] [35] The viscosity and melting point can be decreased by inclusion of small amount of comonomers such as perfluoro (propylvinyl ether) and hexafluoropropylene (HFP). These cause the otherwise perfectly linear PTFE chain to become branched, reducing its crystallinity. [36] Corona discharge treatment of the surface to increase the energy and improve adhesion has been reported. [15] Production [ edit ] Cheaper brands, such as those you would find in high street bargain stores, will have been mass-produced with lower grade materials which allow the low price tag. Though that may sound good for your bank account, you will soon discover you have a tape measure that slices your fingers, screwdrivers that don’t fit in the cross slot of a screw and a hammer grip that is slipping from the handle. These retain the useful PTFE properties of low friction and nonreactivity, but are also more easily formable. For example, FEP is softer than PTFE and melts at 533K (260°C; 500°F); it is also highly transparent and resistant to sunlight. [81] See also [ edit ]
