PTFE – Polytetrafluoroethylene

PTFE or polytetrafluoroethylene is the most known member of the fluoroplastic family. PTFE is inert to almost all chemicals and can be used continuously at temperatures ranging from -240°C to 260°C. Teflon is the trade name of PTFE. It is a proprietary brand of DuPont.

Johnston Industrial Plastics is among the trusted Teflon sheet suppliers. Starting with Teflon plastic sheets, we deliver suitable materials for rollers on a wide range of machines.

PTFE is completely unaffected by outdoor weathering. It has outstanding electrical properties at both high and low temperatures. PTFE has the lowest static and dynamic coefficient of friction in any solid material. It absorbs essentially no moisture. It is cementable only after undergoing special treatment and cannot be successfully welded. Unmodified PTFE is available as skived tape, moulded sheets, rods, tubes, flexible and heat shrink tubing, and thread seal tape.

You may see this material used in machinery that employs rollers. PTFE rollers provide a low-friction solution for businesses that use rollers. PTFE will also not allow anything to stick to it, which can be an advantage in many manufacturing processes.

If you are looking for PTFE sheets, rods, tapes, tubes, and cylinders, Johnston Industrial Plastics is the best source. We are an established PTFE supplier and distributor in Canada. If you and your company are interested in switching to Teflon, call us today. Teflon sheets can provide many benefits to your processes.
