Abstract
A method is disclosed for producing thin-walled small plastic parts having an average wall thickness of less than about 1.5 mm, wherein the small plastic parts are produced in a plastic injection-molding method from polyethylene furanoate (PEF) having a viscosity of, for example, 0.3 dl/g to 0.7 dl/g, for example, preferably less than e.g., 0.6 dl/g, measured according to a measurement method as per ASTM D4603, which polyethylene furanoate has an exemplary water content of less than 100 ppm in the plastic injection process.
