Beschreibung
Zusammenfassung:	A laminate is made of textile sheet structures of synthetic fibers or glass fibers with a covering of polypropylene. The polypropylene is crosslinked by addition of crosslinking agents. The laminate has good electrical insulating properties, perfect solder bath stability, and good mechanical machinability. This laminate is provided, in heated presses, with metal layers or can be provided, in heated presses, with metal layers or can be provided with such metals layers by the application of metallic foils or by electrolytical methods, and serves for the manufacture of printed circuits and ribbon cables. An advantageous production of the textile sheet structures encased with crosslinked polypropylene can be performed on roll stands by thermoplastic encasing and smoothing in a continuous process.
