The present invention provides a non-PVC, non-DEHP material that can be
used for medical grade tubing. Additionally, the present invention
provides medical grade tubing made from such a material. To this end, the
present invention provides a medical grade tubing comprising a multilayer
coextruded structure including: a layer comprising a blend of polyurethane
and polyester; and a layer comprising a blend chosen from the group
consisting of: polypropylene, ethylenevinyl acetate, and polyurethane;
polypropylene and styrene-ethylene-butylene-styrene; polypropylene,
styrene-ethylene-butylene-styrene, and ethylenevinyl acetate;
polypropylene, ethylenevinyl acetate, styrene-ethylene-butylene-styrene,
and thermoplastic polyester elastomer; polypropylene, ethylenevinyl
acetate, styrene-ethylene-butylene-styrene, thermoplastic polyester
elastomer, and polyurethane; polyester, thermoplastic polyester elastomer,
and polyurethane; polyester and polyurethane; and polypropylene,
styrene-ethylene-butylene-styrene, and polyurethane.
