Abstract

1516376 Electrical insulating paper TULLISS RUSSELL & CO Ltd 29 Oct 1976 [10 Nov 1975] 46355/75 Heading D2B [Also in Division C3] Electrical insulating papers are produced from a pulp comprising polyolefin fibrids and a urea or formaldehyde condensate as wetting agent. The pulp may be mixed with or laminated with wood pulp in forming the paper.
