Abstract
Provided are a resin-releasing jig including a base and a releasing layer formed on a surface side of the base, in which the releasing layer is composed of a resin containing a perfluorinated polymer as a main component, and the perfluorinated polymer is crosslinked; and the resin-releasing jig further including a primer layer disposed between the base and the releasing layer, in which the primer layer is composed of a resin containing, as a main component, a perfluorinated polymer and an engineering plastic, the perfluorinated polymer in the primer layer is crosslinked, and the releasing layer has high abrasion resistance and a good adhesive force to the base and thus the resin-releasing jig has good durability. In particular, provided is the resin-releasing jig which is an extrusion molding mold used in an extruder for producing a long resin molded article.
