An aqueous composition for making dip-molded comestible hard capsules comprising a film forming capsule base material and one or more colorants each consisting of a hydrophilic coloring foodstuff concentrate.

A method of manufacturing a semi-crystalline article from at least one pseudo-amorphous polymer including a poly aryl ether ketone, such as PEKK, including a softening step, wherein the at least one pseudo-amorphous polymer is heated to a temperature above its glass transition temperature to soften the polymer, and a crystallization step, wherein the at least one pseudo-amorphous polymer is heated to a temperature between its glass transition temperature and melting temperature, the pseudo-amorphous polymer being placed on a mold during either the softening step or the crystallization step before at least some crystallization takes place. The method results in articles demonstrating increased opacity, increased crystallinity, increased thermal resistance, improved chemical resistance, and improved mechanical properties over articles formed by traditional thermoforming processes.

A dual reactor solution process gives high density polyethylene compositions containing a first ethylene copolymer and a second ethylene copolymer and which have good processability, toughness, and environmental stress crack resistance. The polyethylene compositions are suitable for the preparation of rotomolded parts.

The present invention provides a composite film and a preparation method thereof. The composite film includes polyimide and a dense silica layer formed on a surface of the polyimide.

Compositions may further comprise other components, such as a curing agent and a blowing agent. Articles may include a polymer composition prepared from an ethylene vinyl acetate copolymer, a rubber, and a plasticizer. Methods may include mixing an ethylene vinyl acetate copolymer, a rubber, and a plasticizer; and extruding the mixture thereof.

The present invention is a unique process of manufacturing rigid members with precise “shape keeping” properties and with reflective properties pertaining to radio frequency energy, so that air, land, sea and space devices or vehicles may be constructed including parabolic reflectors formed without discrete permanent layering. Rather, such parabolic reflectors or similarly, vehicles, may be formed by homogeneous construction where discrete layering is absent, and where energy reflectivity or scattering characteristics are embedded within the homogeneous mixture of carbon nanotubes and associated graphite powders and epoxy, resins and hardeners. The mixture of carbon graphite nanofiber and carbon nanotubes generates higher electrode conductivity and magnetized attraction through molecular polarization. In effect, the rigid members may be tuned based on the application. The combination of these materials creates a unique matrix that is then set in a memory form at a specific temperature, and then applied to various materials through a series of multiple layers, resulting in unparalleled strength and durability.

Nanoporous composite separators are disclosed for use in batteries and capacitors comprising a nanoporous inorganic material and an organic polymer material. The inorganic material may comprise Al.sub.2O.sub.3, AlO(OH) or boehmite, AlN, BN, SiN, ZnO, ZrO.sub.2, SiO.sub.2, or combinations thereof. The nanoporous composite separator may have a porosity of between 35-50%. The average pore size of the nanoporous composite separator may be between 10-90 nm. The separator may be formed by coating a substrate with a dispersion including the inorganic material, organic material, and a solvent. Once dried, the coating may be removed from the substrate, thus forming the nanoporous composite separator. A nanoporous composite separator may provide increased thermal conductivity and dimensional stability at temperatures above 200° C. compared to polyolefin separators.

The present invention relates to a flexible molded skin as part of a composite structure for an airbag cover, and to a composition for producing such a skin using slush molding. The composition and flexible molded skin have a thermoplastic plasticized vinyl polymer, and a tear promoting agent selected from the group of one or more particulate blowing agents, inorganic mineral materials, organic filler materials and microspheres or a mixture of two or more of the afore mentioned materials. The particles of the particulate tear promoting agent have an average particle size of between 0.005 and 50 μm, preferably between 0.005 and 40 μm.
