摘要:
A process for the manufacture of fibre-reinforced intermediates useful in thermoplastic processing methods, including compounding and moulding, which comprises impregnating continuous fibres with a resin composition comprising at least one radiation-polymerizable component, exposing the impregnated fibres to radiation to effect polymerization of such component, and cutting the product to form thermoplastically processible intermediates which, optionally, may be mixed with other polymer and/or additives during mixing or moulding. A process described as above but in which the uncut radiation polymerized fibre-resin product is blended with a least one polymer and/or additive in a continuous mixer, such as an extruder; and the resulting blended product is cut to form thermoplastically processible intermediates, such as mouldable pellets.
摘要:
A process for producing a thermoformable fibre-plastics composite product comprising lignolcellulosic or natural fibres, particularly but not exclusively useful as an intermediate product in subsequent manufacture, comprises conveying the fibres in a dry or wet air stream and applying to the fibres a thermoplastic binding agent, and forming the fibres into a solid or semi-solid product such as a panel, which is thermoformable. In at least a preferred embodiment the process may be carried out in known plant for manufacture of medium density fibre board.
摘要:
A process for producing pellets or granules comprising fibers of a lignocellulousic material, for use as a feedstock in plastics manufacture, conveying in a dry or wet air stream and applying to the fibers a liquid formulation comprising one or more polymers, monomers, or oligomers, forming the fibers into a solid product, and breaking down the solid product to produce said pellets or granules. Typically the conduit conveys the fibers in a plant for manufacture of fiber board.

摘要:
This invention relates to a polymer mixture which comprises an aromatic polycarbonate (A); a styrene (or styrene derivative and/or (meth)acrylate) containing polymer or copolymer and/or a styrene (or styrene derivative and/or (meth)acrylate) containing graft polymer (B); phosphorous compound(s) which are phosphate or phosphonate or oligomeric or poly-phosphate based flame-retardant(s) (C); specific inorganic additive(s) (D); and further flame retardant(s) or anti-drip agent(s) (E): and optionally, other additives.
摘要:
A process for producing a thermoplastic elastomer comprising dynamically curing with a peroxy curing agent (A) nitrile rubber and (B) homopolymer or copolymer of ethylene, which is curable with the peroxy curing agent but excluding copolymers comprising ethylene and an acrylic or methacrylic ester. The thermoplastic elastomer composition produced by the process is suitable for use in sealant or adhesive compositions, particularly when blended with a tackifying resin.
摘要:
A process for producing a composite product comprising fibers of a lignocellulosic material or natural fibers and a plastics material utilizes a liquid or particulate binder formulation comprising a thermoset resin and a thermoplastic polymer, monomer, or oligomer. A composite product is formed for use as or in forming a feedstock in plastics manufacture may be broken down under heat and mechanical shearing in a plastics extrusion machine to release the major fraction of the fibers, or the product may be useful as an intermediate product in other form or as an end product.
