The present invention provides a process for modifying the surface of a polyvinyl alcohol film or fabric by applying heat and pressure to the film or fabric to increase the moisture on the surface which is held by the fabric and to coalesce the surface fibers and reduce the porosity of the surface.

A method for manufacturing a pressure container includes thermally curing a thermosetting resin with which a fiber-reinforced base material is impregnated. The thermally curing step includes thermally curing the thermosetting resin by heat exchange with a fluid supplied to an inside of a liner; and thermally curing the thermosetting resin by heating from an outer surface side of the fiber-reinforced base material. A temperature of the fluid supplied to the inside of the liner is higher than a temperature of the helating from the outer surface side of the fiber-reinforced base material so that the thermosetting resin is thermally cured from an inner surface side of the fiber-reinforced base material adjacent to the liner before the outer surface side of the fiber-reinforced base material.

A molding process includes the operation of placing insulation material comprising fibers and binder on the fibers in a mold cavity. The molding process further includes the step of transferring heat to the insulation material to cause the binder to cure.

The present invention refers to co-extrusion of one or more polyolefins with one or more adhesive layers to improve the adhesiveness of the polyolefins in metal, epoxy resin, glass, ceramics, paper, wood, thermoplastic resin, fabric, non-woven fabric, varnishes and formica. More specifically, the present invention refers to a method of co-extruding at least one polyolefin with an adhesive layer, thereby enhancing the adhesion properties of the polyolefin, particularly in polyurethane foams such that a polar surface is imparted to the obtained adhesived polyolefin.

The present invention related to an apparatus and method for the manufacturing of beverage capsules. The apparatus can preheat the material used to form the beverage material during the manufacturing process. The material and apparatus are particularly suitable for use in producing single serve beverage capsules from biodegradable materials.

In one aspect, inks for use with a three-dimensional (3D) printing system are described herein. In some embodiments, an ink described herein comprises 10-70 wt. % cyclopolymerizable monomer, based on the total weight of the ink. The cyclopolymerizable monomer comprises a first ethenyl or ethynyl moiety and a second ethenyl or ethynyl moiety. Additionally, the α-carbon of the first ethenyl or ethynyl moiety and the α-carbon of the second ethenyl or ethynyl moiety have a 1,5-, 1,6-, 1,7-, or 1,8-relationship.

A ventilation module is disclosed having a ventilation outlet channel including a gas flow inlet side and an opposite gas flow outlet side. The ventilation outlet channel is separated in the longitudinal direction to form at least two ventilation channel portions, such that the at least two ventilation channel portions are adjustable away from and towards one another transversely to the longitudinal extent of the ventilation outlet channel. The width of the ventilation outlet channel and thus the flow cross section can be increased or decreased.

A method for producing thermally crosslinkable polymers in a planetary roller extruder is presented. The planetary roller extruder has a filling part and a compounding part made of a roller cylinder region that comprises at least two, preferably at least three coupled roller cylinders, planetary spindles of which are driven by a common central spindle. The polymers are supplied in a plasticized state. The filling part is supplied with a vacuum. The flow temperatures of the central spindle and the at least two roller cylinders under a vacuum are set such that the polymers to be degassed remain in the plasticized state. One or more liquids, such as thermal crosslinkers, crosslinking accelerators, dye solutions, or dye dispersions, are metered to the plasticized polymers downstream of the vacuum degassing, preferably in a continuous manner. Finally, the resulting mixture is directly supplied to a coating assembly.

The present invention relates to a composition comprising (i) an unsaturated dicarboxylic acid, an ester or an anhydride thereof and (ii) aliphatic diol, (iii) dianhydrohexitol, (iv) cycloaliphatic diol and/or aromatic aliphatic diol, and (v) an amide-forming agent. Further, the invention relates to an unsaturated polyesteretheramide obtainable by condensation of the composition of the invention and to an unsaturated polyesteretheramide resin comprising the unsaturated polyesteretheramide and a reactive diluent. The invention further relates to a thermoset with high thermo-mechanical properties.
