A mouldable product such as a pad which can be selectively transformed between pliable and rigid states is formed of a sealed plastic container which houses a metastable compound such as sodium acetate tri-hydrate, a trigger device for initiating the nucleating process in the compound to render it rigid, and a reinforcing open micro-porous material. The material may be fibrous, e.g., cotton, and stabilizes the product in its rigid state for a comparatively long time.

An injection mouldable material and a method of making the material wherein the material comprises a mixture of an injection-mouldable polymer and a dielectric substance having a relatively high dielectric constant. The dielectric substance is preferably a ceramic. Such material is particularly suitable for the manufacture of planar antennas. The polymer preferably has a loss tangent equal to or less than 0.01 and greater than or equal to 0.002.

There is provided a mouldable composition for use in manufacturing a sintered metal or ceramic object, the composition comprising a metal or ceramic powder, a cross-linkable thermoplastic polymer and an amount of a cross-linking agent effective to cross-link the thermoplastic polymer at an elevated temperature. There is also provided a process for manufacturing a sintered metal or ceramic object using such a mouldable composition.

A biocompatible moldable curable polymer/monomer system capable of curing at ambient temperatures to provide an elastomer product while producing a lower exotherm than previously used systems. The system includes an alkyl acrylate or methacrylate homopolymer or copolymer; a monomer mixture of higher alkylacrylate or methacrylate combined with one or more of acrylic acid, methacrylic acid and their lower alkyl esters; and a plasticizer and optionally cross-linking agents, anti-tack agents, and ac...

A moulded alum composition is formed by mixing crushed solid alum with a polyol plasticiser followed by heating to form a slurry, and then pouring the mixture into a mould. No mechanical cutting and grinding is required and weakening cracks and fissures present in the raw alum are removed.

A mouldable pressure-sensitive hydrocolloid adhesive composition, particularly useful as a medical adhesive, comprising a dispersion of a discontinuous phase of one or more water-soluble and/or water swellable absorbent polymers in a continuous phase comprising a thermoplastic elastomer, a compatible liquid rubber, a polyisobutylene and a low-molecular weight polybutene.

A thermoplastic article formed of a composition for customizable moulding parts of devices such as hand grips or sports equipment or orthopaedic equipment comprises a composition which is set below 37.degree. C. and is conformably mouldable between about 50.degree. C. and 95.degree. C. The article can be moulded, used, and re-moulded and re-used, repeatedly. Such a composition may be an acrylate polymer, possibly a methacrylate polymer. The acrylate polymer may soften or become liquid in the ran...

A mouldable photographic material is made up from a thermoplastic base sheet, and a primer coating which provides the key for a photographic emulsion layer. Following exposure and development, a thermoplastic foil is laid over the emulsion layer and bonded in place using an optical quality adhesive.

A mask for supplying gas under pressure to the nasal airway of a human includes a series of flexible stretchable straps formed from an elastomeric material for locating the mask against the human face. The straps are integrally formed or joined to define a perimeter enclosing an aperture adapted to fit around the nasal area of a human. The straps are configured to approximate to the three dimensional shape of the region around the nasal area of the human face as they arm stretched, to form a tig...

Substantially monomer-free, electrically conductive organic polymers and/or organic conductors are dissolved or dispersed in a melt or solution of a thermoplastic matrix polymer or polymer mixture partially compatible therewith and having a solubility parameter >8.6 (cal/cm.sup.3).sup.1/2, in order to obtain mouldable polymer blends. The latter are suitable for producing moulded articles, particularly for electrical conductors, semiconductors or photoconductors. A suitable apparatus for produ...
