Physical & Mechanical Properties of PTFE Tubing
PTFE (polytetrafluoroethylene) is a synthetic fluoropolymer or plastic, better known by its familiar trade name, Teflon. The physical and mechanical properties of PTFE have made it an exceptionally useful material, with many applications. As one of the most widely used engineering materials since its discovery in 1938, PTFE is now found in all industries. It is one of the most well-known plastics and used in one form or another in just about every household, factory, or business. Of its many mechanical properties, it is especially known for its low coefficient of friction—there is virtually nothing that will stick to it. For that reason, just about every non-stick coating pan and similar cookware are nicknamed, “Teflon.”
Unique Properties of PTFE
More than Teflon-coated pans, PTFE’s many unique properties have led to diverse, advanced applications. Its versatility gives it a big advantage over other like materials. In addition to its low coefficient of friction, it has unparalleled chemical resistance and extreme temperature tolerance, it is thermally stable and has high environmental flexibility, is water-resistant, non-conductive, non-flammable, non-adhesive, and dense.
These properties have made PTFE beneficial in a wide range of applications for many products in different industries. It’s used for storing or transporting corrosive chemicals, found in lifesaving medical devices, coating machinery and parts like ball bearings, gears, or screws, for industrial equipment operating in demanding environments, and for making tubing. PTFE’s non-reactive synthetic fluoropolymer structure offers a unique combination of properties.
PTFE’s wide use in containers, piping and tubing stems from it being chemically inert, which gives the material its highly insoluble, acid-resistant properties. Because of its excellent dielectric properties, PTFE is non-conductive and has exceptional insulating properties. This makes the material a very good choice for tubing and insulating where electrical and electronic devices, components and cabling have high electrical fields or require the high-frequency transmission of signals without conduction.
In addition to its acid resistance and electronic insulation, other advantages for PTFE’s usefulness as a tubing material are its density and thermal properties. PTFE’s high density provides very good impact resistance, making it durable and tough. Thermal stability is also a big plus. PTFE is flame retardant with a melting point of approximately 327 C or 620 F. It retains its properties without degrading in cryogenic temperatures of -200 C (-328 F) all the way up through 288 C (500° F).
With PTFE’s many unique properties—acid resistant with excellent electrical insulation, exceptional weatherability, moisture and water-resistant, non-adhesive with a low coefficient of friction, outstanding thermal stability—it’s used in a wide variety of applications.
PTFE Tubing from M.M. Newman Corporation
M. M. Newman Corporation offers PTFE extruded tubing in a wide selection of sizes. We also have Industrial Heavy Wall Tubing and AWG Sizes in Standard Wall and Thin Wall tubing. Just like Heli-Tube® Spiral Cable Nylon Wrap and Abrasion Protector, PTFE tubing is an ideal application for organizing wires and cables in moderate, mild or extreme conditions. The PTFE tubing offers protection for all cabling needs. The material is lightweight, highly abrasion-resistant, non-flammable, and will operate in a wide temperature range. It will also withstand the harshest, corrosive conditions, but also protect cabling against general wear and fraying. Overall, M. M. Newman’s PTFE tubing is a high-performance, long-lasting material that will meet your application needs.
