A liquid colorant for use in molding or extruding plastic products comprises pigment dispersed in cottonseed oil.

The present invention relates to heat-stabilized polyamide 66-based compositions containing reinforcing materials based on at least one semiaromatic polyamide, at least one phenolic antioxidant and at least one polyhydric alcohol, to molding materials producible therefrom and in turn to injection-molded, blow-molded or extruded articles of manufacture producible therefrom.

A method for producing a 3D structure, according g to which a composite conductive substrate (CCS) with a conductive layer and a non-conductive layer is provided and a conductive pattern is determined for each layer of the 3D structure. A first layer of non-conductive matter on the CCS is printed, such that the conductive pattern of the first layer left empty from the non-conductive matter. The empty conductive pattern is filled with conductive matter by electroplating and for each following layer, in turn, printing, on the previous layer, a layer of non-conductive matter, the conductive pattern of the present layer left empty from the non-conductive matter; plating non-conductive areas of the previous layer that are left uncoated with conductive matter; and filling the empty conductive pattern of the present layer with conductive matter by electroplating.

An additive article stabilizing method includes prior to polymerization, adding a radiation-activated stabilizing composition to a liquid resin, forming the article from the liquid resin, layer by layer, using radiation such that the stabilizing composition does not stabilize the liquid resin but the formed article, and neutralizing free radicals generated during a degradation process initiated by exposure of the article to additional radiation post-cure.

A polyarylene sulfide resin composition characterized by comprising a polyarylene sulfide resin, and an olefinic copolymer comprising an -olefin-derived structural unit and an ,-unsaturated acid glycidyl ester-derived structural unit, wherein the olefinic copolymer content is at least 1.0 parts by mass and less than 5.0 parts by mass with respect to 100 parts by mass of the polyarylene sulfide resin, a melt viscosity of the polyarylene sulfide resin measured at 310 C. and a shear rate of 1216 sec.sup.1 is at least 70 Pa.Math.s and at most 300 Pa.Math.s, and a flow length for a width of 20 mm and a thickness of 1 mm, at a cylinder temperature of 320 C., an injection pressure of 100 MPa and a mold temperature of 150 C., is at least 80 mm and at most 200 mm.

A method for producing highly spherical polymer particles comprising a polyamide having an optical absorber in a backbone of the polyamide (IBOA-polyamide) may comprise: mixing a mixture comprising the IBOA-polyamide, a carrier fluid that is immiscible with the IBOA-polyamide, and optionally an emulsion stabilizer at a temperature greater than a melting point or softening temperature of the IBOA-polyamide and at a shear rate sufficiently high to disperse the IBOA-polyamide in the carrier fluid; and cooling the mixture to below the melting point or softening temperature of the IBOA-polyamide to form particles comprising the IBOA-polyamide and the emulsion stabilizer, when present, associated with an outer surface of the particles.

A process for flexibly making a wetsuit or the like is disclosed by integrally forming a functional surface layer on a rubber foam substrate sheet, thereby rendering the function of the surface layer for the wetsuit or the like.

The invention includes a method of providing an intermediary layer in a laminated structure, between two adjacent layers, where the intermediary layer contains a fiber having an extrusion coating. The intermediary layer may form a textile constructed from the fibers, the intermediary layer, when the lamination method proceeds, provides the adhesion between the adjacent layers, as well as reinforcement for the laminated structure.

The disclosure relates to a method for producing an extruded sheet, which includes: a) providing calcium carbonate (CaCO.sub.3) powder; b) providing polyvinyl chloride (PVC) powder; c) providing additives as stabilisers; e) heating the mixture until the PVC softens to form a kneadable mass and the CaCO.sub.3 at least partially bonds to the PVC; f) cooling the mass; g) conveying the mass to an extruder; h) melting and extruding the mass by means of an extruder and moulding into a sheet by means of a slotted nozzle; i) pressing the still-warm sheet to a desired final thickness by means of at least two calendar rolls; and j) at least one layer of a pigmented lacquer is applied to the upper side; and k) an additional lacquer is applied to the pigmented lacquer to increase the scratch resistance.
