Urethane/polyester coextruded medical tubing targets PVC replacement

摘要

This coextruded tubing elimiantes the environmental concerns of PVC and the toxicity concerns of palsticizers. The coextruded tubing does not have the yellowing problems of polyurethane tubing. Developer of the new 'BioPath tubing is the Natvar Div. of Tekniplex co., where engineering manager Bob Donohue tells us, "Many of our customers within the United States and overseas are looking to switch to non-PVC products to eliminate health and disposal concerns, but up to this point there have been performance and processing issues associated with non-PVC alternatives. The goal in the industry has been to do away with PVC and plasticizers, but the right product just wasn't there."
