FEP-Lined Tubing

摘要

DelStar Technologies, Inc announced a new Coretec~R FEP tubing product, designed to offer cost effective solutions for high performance fluid and gas processing applications.The new tubing has an inner lining of Teflon~R FEP (fluorinat-ed ethylene propy-lene) encased in a protective, and less expensive, LDPE (low density polyethylene) jacket.DelStar Technologies is now stocking five sizes of this FEP-lined fractional tubing. The FEP inside diameters (I.D.) range from 0.170 to 0.625" (4 to 15 mm), and the LDPE outside diameters (O.D.) range from 0.25 to 0.75" (6 to 19 mm). The product is available in custom lengths.By lining the inner surface of LDPE tubing with FEP, this tubing provides the benefits of FEP at a percentage of the cost. The FEP lining offers a chemically inert, non-adherent surface, with a very low coefficient of friction and low permeability. It also exhibits excellent chemical resistance, as well as thermal and electrical stability.
