Laminated thermoplastic sheet eg for drawings - comprising layer of synthetic polymer, and layer of softenable polymer contg. finely divided particles

摘要

Laminated sheet has (I) a layer of a main synthetic polymer sheet, (II) a second layer of a softenable synthetic polymer, and (III) particles of a material with an average particle size below 100 mu esp. 25 mu welded to and/or embedded in the second layer. Laminate has a wide variety of uses e.g. in heating elements, printed circuits, magnetic tapes, packaging and copying materials.
