Abstract
Polymers having low surface energy, e.g. fluorocarbon polymers, are rendered printable by conventional methods, e.g. offset printing, by incorporating a suitable particulate filler in the polymer, and shaping the filled polymer under conditions which result in the surface of the shaped polymer having irregularities which correspond to the particles of the filler. Suitable fillers comprise particles having at least two dimensions in the range of 1 to 40 microns; glass fibers are particularly satisfactory. Extruded insulating polymeric jackets for electrical components, e.g. strip heaters and wire and cable, can readily be marked by use of the invention.
