Hollow Bar in PTFE 14/12x100000 mm natural

PTFE is the material with the best sliding properties and the most extreme chemical resistance in the whole range. Nothing sticks to the surface, and the material stands up to practically all chemicals. The coefficient of friction against steel is only 0.08 in dry running, that is, without lubrication, the lowest of all our plastics. It handles 260 degrees continuously and all the way down to -200 degrees, a temperature range no other plastic in the range manages, and it does not melt until 327 degrees. PTFE does not burn, entirely without flame retardant additives, because the fluorine in the material does the job. The price you pay is low mechanical strength: the tensile strength is only 24 MPa and the material creeps under load, so it is not a load bearing structural material. The density of 2.17 is also high for a plastic.

This product is a hollow bar in PTFE, 14 mm outer diameter and 12 mm inner diameter, in natural color. A hollow bar is the format with a hole straight through, so a seal, bushing or insulating sleeve can be turned directly from the bar without first boring out a solid rod. The thin wall makes it an obvious choice for hose couplings and bushings in a chemical environment. If you want the bar cut to size, add CTS to the cart.
