<p>A process and a tool facilitate processing of thermoplastic polymers, in particular of linear polyethylene. The inner surfaces of the processing machine which come into contact with the plastic polymer material are totally or partially degreased, roughened, and, if necessary, treated chemically and/or provided with a primary coat, and then coated with one or more layers of fluoropolymers or fluoroelastomers containing 35 to 76 % by mass of fluorine and having a molar mass of at least 105.</p> |
