Abstract

1478576 Rolling thermoplastic sheet; pressure-rolling; laminates NIPPON PETROCHEMICALS CO Ltd 29 July 1975 [31 July 1974 2 July 1975] 31641/75 Headings B5B B5A and B5N [Also in Division C3] Films and sheets of thermoplastic resins are orientated by pressure rolling, the film or sheet being passed between a pair of rolls rotating in different directions and at different peripheral speeds. The material is at a temperature below the softening point or the crystalline melting point of the resin. In one embodiment the film or sheet may be taken up at a greater speed than the rollers deliver it; in another the material is maintained in contact with the faster roller for longer than required by passage through the nip. The material may be supplied as a flattened tubular film, which yields a 2-ply laminate, or as several films or sheets, which the pressure-rolling bonds together. In examples the tubular film is made of high density polyethylene, polyvinyl chloride and polypropylene. In other examples 2-ply tubular films comprised of polypropylene/h.d. polyethylene; h.d. polyethylene/ionomer; and polyamide/h.d. polyethylene are extruded, collapsed and pressure-rolled. Laminates exemplified are comprised of layers of h.d. polyethylene laminated to l.d. polyethylene, polypropylene, ionomer or polyamide and polyamide laminated to polypropylene. Single films or sheets exemplified are compression-moulded h.d. polyethylene, polyethylene admixed with glass fibre or calcium carbonate filler, foamed h.d. polyethylene and of h.d. polyethylene mixed with copolymers of styrene/butadiene, styrene/isoprene or ethylene/ propylene and with butyl rubber or polyisobutylene.
