Abstract: 1,252,603. Laminates. FARBWERKE HOECHST A.G. 7 May, 1969 [7 May, 1968], No. 23246/69. Heading B5N. [Also in Divisions B2 and C3] Laminates comprise a sheet or plate of polytetrafluoroethylene or metal foil or plate and a layer of an open-pore cellular polymer of a perfluorolefine, e.g. polytetrafluoroethylene, of density 70-1000 kg./m. 3 and which retains form stability up to at least 250‹C., with optionally 1-20% by wt. of a filler, e.g. glass fibres or water glass. The laminate may be made by incorporating into an aq. dispersion of the polymer, 3-10% by wt. of a hydroxyhydrocarbon having at least 3 hydroxyl groups, e.g. glycerol, cane sugar, sorbitol or glycose, and then introducing a gas, e.g. air, while whipping until a rigid foam is obtained which is applied to a substrate, e.g. sheet or plate of polytetrafluorethylene or a metal plate or foil e.g. an aluminium foil, and then heated at 80‹ C. or higher at increasing temperatures until sintering at 330-450‹ C. A surfactant, e.g. sulphonated lauryl alcohol oxethylate, may be present during the foaming.

Abstract: (Co)PVC films with mat and rough surfaces, which contain a stabiliser and lubricant and are produced by roller-kneading calendering, contain 10-40 pref. 15-35 wt. % polymer (I) of Mw 110,000-190,000 and 60-90, pref. 65-85 wt. % polymer (II) of Mw 45,000-75,000. The films are receptive to (printing) inks, lead pencil etc. and can be used as record sheets. They are also useful for furniture, cassette or credit card films. The film can be made by a simple and economical process and no special matting agent is needed. The chemical, electrical and mechanical properties e.g. tensile strength, elongation, impact strength, etc., are in the usual region for PVC films and the use of the blend does not increase mfg. costs.
