Polystyrene foam packaging material - from peeled thin foam strips with bonded outer paper layers

Packaging material consists of polystyrene foam which carries outer layers on both sides. The polystyrene foam is produced not by extrusion but by peeling it off a cylindrical block by scalping blades to a thickness of 1.5 mm. Two layers of different thickness and grade are bonded to the two sides. The other layers may be paper and carton applied using an adhesive. This is cheaper than extrusion and is suitable for much thinner layers which are impermeable to water or grease but can be printed directly in conventional machines.

Sandwiching thermoplastic foam between e.g. sheets of paper - using only elect ostatic attraction to exert the necessary pressure

Foamed plastic from a roll is passed between charging electrodes, then on through the space between two rollers, round which the covering sheets are fed. After dwelling on a conveyor long enough for the plastic to cool, the now-covered material passes out between discharge electrodes. The heat for melting the plastic foam is obtained by passing the covering sheets round heated rollers on their way to the layering rollers; auxiliary rollers tension the sheets before they are laid. When the heated covering sheets were applied to the foamed thermoplastic (polystyrene) under the pressure of rollers, the pressure eliminated undesirably many air spaces from the softened foam. In the present method a minimal pressure is exerted electrostatically.

Wooden wall external cladding system - applies absorbent layer to aluminium sheet before hot pressing onto glued wall

The external cladding system uses aluminium sheet on walls of wood or similar material, partic. in the manufacture of caravans. In a single, and pref. continuous operation, an intermediate coating of absorbent material is applied to one side of the aluminium sheet, after which the outside of the wall to be clad is coated with adhesive. The sheet is then applied to the wall with its coated side towards the latter, and the two are hot-pressed together. An adhesive can be used to secure the absorbent material to the sheet. The material can be applied only to part of the sheet surface, and can comprise particles of wood, a prefabricated strip of material, or foam.

Fire resistant foamed material for coatings, insulation or mouldings - made by adding hydrogen peroxide to mixt. of magnesium chloride and magnesia

Material is based on Mg oxychloride or Mg oxychloride-cement, starting from an aq. suspension of the MgO and/or Mg(OH)2 with MgCl2; the suspension also contains fibres esp. chopped glass fibres, and a surfactant. The suspension is converted into foam by adding a foam ant, viz. H2O2 and/or other peroxide evolving O2, plus an activator, esp. an Mn (II) cpd., and also a pore promoter, viz, a water-soluble or -dispersible cellulose-deriv., -ether, or -ester, and/or a dispersion of synthetic resin. The glass fibres are pref. chopped glass mats or fabric with fibre length 2-7, esp. 3-5 mm. The material is used esp. as a coating 0.3-12, esp. 1-4 cm thick on metal, wood, concrete, brickwork, building elements, plastics. Use of Mg powder as a foamant is avoided because the Mg constitutes a fire hazard both in the mfr. and use of this type of material.
