ROHRFÖRMIGES LAMINAT UND DESSEN HERSTELLUNG

摘要

A process for producing a tubular laminate which comprises subjecting the surface of a tubular fluororesin molding to electric discharge treatment in an inert gas atmosphere containing a functional organic compound and coating the resultant surface with a molten resin by extrusion. This process can provide a firm adhesion between the fluororesin molding and the coating resin even without using any adhesive, whereby the step of applying an adhesive can be dispensed with and a tubular laminate can be produced continuously.
