Ptfe tubing has high chemical resistance, low and high temperature capability, resistance to weathering, low friction, and electrical and thermal insulation. The mechanical properties of these chemical resistant tubing are low compared to other plastics, but they are often enhanced by adding fillers such as glass fibers or carbon. When filled, ptfe tubing maintains its excellent chemical and temperature resistance properties, while fillers improve mechanical strength, stability, and wear resistance. Because of its non-reactive nature, it is often used in containers and pipework for reactive and corrosive chemicals. Ptfe tubing features a low friction coefficient that allows higher flows and easier washdown, while also helping to eliminate process-contaminating residue. The material is flexible, chemical resistant, nonflammable, and heat resistant.

Ptfe tubing may be used to connect the gas lines to the ports during gas chromatography-mass spectrometry analysis of volatile organic compounds from potato tubers inoculated with phytophthora infestans or fusarium coeruleum. Heating tube to soft point prior to bending is best for permanent bends. Tried these as vent tubes for roto molding in place of virgin teflon ptfe we usually used and they worked equally well. We will be changing to this product, because we are able to purchase smaller quantities.
The unique properties of ptfe tubing cover an impressive range. However, mechanical strength and wear resistance are not criteria for which ptfe is recommended, which is one reason for the development of fep tubing, pfa tubing and etfe tubing. Ptfe is the classic, original, and gold standard of fluoropolymer tubing. Ptfe was the “Miracle” fluoropolymer invented in the 1940’s by dupont – a product originally without a market and hard to process. Most other materials continue to use ptfe as a reference for chemical resistance. Flexible, heat-resistant ptfe tubing offers a low friction coefficient that provides higher flows and washdown that reduces process-contaminating residue.
