  • Coextruded tubing
    Patent number: 6431219
    Abstract: Flexible medical grade PVC tubing has inner and outer layers coextruded with different plasticizers, with the first, inside layer of the tubing containing a plasticizer, such as di-ethylhexyl adipate, and having a thickness adapted to limit migration of a second plasticizer, such as di-ethylhexyl phthalate, from a second, outer layer of the tubing to the inside of the tubing. The flexible medical grade tubing can optionally include a third, outermost layer surrounding the second layer and containing a plasticizer such as di-ethylhexyl adipate, so that the third layer limits migration of the second plasticizer to the outside of the tubing.
