ABSTRACT:
An extrusion die for extruding at least two layers of polymers at substantially different temperatures wherein a first die has portions connected to a second die and portions spaced from the second die. Insulation is provided between the first and second dies and the first die is water cooled. A layer of insulation is provided between the spaced portion of the first and second dies. A third die is mounted to the second die and co-extrudes a third material onto the laminate formed by the first and second dies. The third die is connected to the second die but has portions spaced from the second die. The spaced portion between the second and third dies are insulated. A thermosetting polymer, such as FKM, is extruded by the first die at a temperature of about 180.degree.-200.degree. F. A fluorinated, thermoplastic polymer, such as THV, is extruded from the second die at a temperature of about 480.degree. F. A thermosetting polymer, such as ECO, used to extrude multilayered fuel tubing.
