The present invention is directed to an article of manufacture, which can be a fiber and or a film. In one aspect, the fiber or the film comprises a polyvinyl alcohol (PVOH) and an inorganic filler comprising particles having an average diameter of less than about 20 micrometers. The PVOH has a degree of hydrolysis of greater than about 95% and is present in a range between about 20 wt. % and about 99 wt. % based on the total fiber weight. Methods of making the fibers and films are also disclosed.

A process for manufacturing a composite automobile part by overmoulding, over at least one surface of an insert (1) comprising a first plastic material, a layer of a second thermoplastic material, comprises the following successive steps: a) a step of positioning said insert (1) in a mould, and b) a step of moulding said second thermoplastic material over said insert. At least one of said first and second materials comprises an additive, said additive comprising a polymer to which carboxylic anhydride monomers are grafted. Said first and second materials are respectively based on polyamide and based on polypropylene, or vice versa and said second material comprises talc as mineral filler.

Microporous breathable films include a polyolefin and an inorganic filler dispersed in the polyolefin.

Embodiments disclosed herein relate to polymer resins having a first thermoset and one or more additional components (e.g., a second thermoset and/or a thermoplastic), composite laminates including the same, methods of making and using the same, and composite laminate structures including the same.

A method of manufacturing hexagonal boron nitride laminates contains steps of: a) Dissolving dielectric polymers in solvent. b) Mixing h-BN powder to form a well-mixed h-BN coating slurry. c) Coating slurry on substrates and dried at 100 to 150° C. d-1) For free standing h-BN film, peel off h-BN dielectric polymer layer from substrate in water batch by roll to roll process. d-2) For h-BN film on substrates, heat compression of the substrates and hBN laminates at 100 to 250° C. for multi-layer structures. Thereby, hexagonal boron nitride laminates exhibit thermal conductivity of 10 to 40 W/m.Math.K, which is significantly larger than that currently used in thermal management. In addition, thermal conductivity of hexagonal boron nitride laminates increases with the increasing mass density, which opens a way of fine tuning of its thermal properties.

An oriented film includes an orientated semi-aromatic polyester layer and a thermally conductive filler dispersed in the orientated semi-aromatic polyester layer. The thermally conductive filler is at least 20% wt. of the oriented film.

Provided is a resin sheet, wherein in a stress measurement in which a dynamic shear strain is applied in a direction parallel to a surface, the difference between a loss tangent as measured when a strain amplitude is 10% of the sheet thickness and a loss tangent as measured when the amplitude is 0.1% is equal to or greater than 1 at a temperature of 80° C. and a frequency of 0.5 Hz. The resin sheet of the present invention can provide a semiconductor device with excellent connection reliability, wherein air bubbles and cracks are less likely to occur in the resin sheet. In the resin composition of the present invention, aggregates are less likely to occur during storage. The resin sheet obtained by forming the resin composition into a sheet has good flatness. The hardened material thereof can provide a circuit board or a semiconductor device with high connection reliability.

A method of producing a directly blow-formed container. The method includes subjecting a multilayered parison having an inner surface formed of an olefin resin to direct blow forming, the olefin resin containing (i) an organic bleeding lubricant having a melting point of not higher than 50° C. in an amount of 5 to 10% by mass, and (ii) a high silica zeolite having a silica/alumina mole ratio of not less than 80 in an amount of 0.2 to 3.0% by mass.

Provided is a Fresnel lens which has excellent heat resistance and which can covert light even from a poor-quality semiconductor light sources into uniform, high-quality light and can disperse the resulting light without lowering the central illuminance. The Fresnel lens according to the present invention includes two or more sawtooth prisms in a surface thereof and is made of a cured product of a curable composition containing an epoxy compound (A). Of the sawtooth prisms, a sawtooth prism having a longest inclined side in a cross section has a roughened surface, where the cross section is given by cutting the Fresnel lens in a plane which passes through the center of the Fresnel lens and which is perpendicular to a reference plane of the Fresnel lens.
