摘要:
Disclosed is a shaped article comprising a composition comprising polyamide and ionomer wherein the ionomer comprises a mixture of Zn and alkali metal (M2) cations wherein the Zn/M2 equivalent ratio is from about 0.6 to about 6. The articles prepared from the compositions with mixed ion ionomers exhibit high stiffness, hardness and toughness, good scratch resistance, desirable low melt viscosity and high processability.

摘要:
Light concentrating articles capable of concentrating about 1.02 to about 2000 sun equivalents of solar energy onto a solar cell comprise a thermoplastic composition, preferably an ionomer composition. The light concentrating articles may be made by a variety of processes, which are provided herein, such as for example an injection molding process, an injection overmolding process, an extrusion process, a cast film or sheet process, a blown film or sheet process, a vacuum forming process, a compression molding process, a transfer molding process, or a profile extrusion process. Secondary forming processes, such as bending, stamping, embossing, machining, laminating, adhering, metallizing, and the like may also be used in forming the light concentrating articles.
摘要:
A multilayer film structure is disclosed which comprises at least a first layer made of a bio-based polymer composition; a tie layer comprising one or more ethylene copolymers and one or more inorganic fillers; and optionally at least one additional layer.
摘要:
A composition and an article therewith are disclosed wherein the composition comprises or is a blend that comprises, consists essentially of, consists of, or is produced from, about 1 to about 40, or about 5 to about 35, about 10 to about 30, or about 10 to about 20 or 25% of a polyamide and about 60 to about 99, about 65 to about 95, about 70 to about 90, or about 75 or 80 to about 90% of an ionomer, all based on the weight of the blend.
摘要:
An antistatic styrenic polymer compositions comprises 30 to 70 wt % of a styrenic polymer, 5 to 40 wt % of a potassium ionomer, 1 to 10 wt % of one or more polyols, and 2 to 20 wt % of an ethylene copolymer, based on the total weight of the styrenic polymer composition which, if compared with compositions of the state of the art, shows reduced dust absorption and improved mechanical performances. Also disclosed are articles made of the composition such as film or sheet including multilayer structure and items obtained by extrusion molding, coextrusion molding, injection molding, thermoform molding, compression molding or blow molding.
摘要:
Disclosed is a method for preparing filled polypropylene compositions comprising mixing a dicarboxylic acid anhydride-grafted polypropylene resin and an ethylene/vinyl acetate copolymer or an ethylene/alkyl (meth)acrylate copolymer with polypropylene, filler and optionally an elastomer. Also disclosed are compositions comprising a dicarboxylic acid anhydride-grafted polypropylene resin and an ethylene/vinyl acetate copolymer or an ethylene/alkyl (meth)acrylate copolymer that can be used as compatibilizers or coupling agents allowing preparation of polypropylene compositions filled with, for example, glass fibers. The glass-filled resin composition exhibits excellent finishing properties, such as adhesion, coating properties, and printability, as well as improved rigidity and thermal properties.
摘要:
A thermoformable multi-layer sheet is disclosed, which comprises or is produced from a first co-extruded clear polymeric layer comprising an ionomer resin; a second co-extruded polymeric layer; a third co-extruded thermoformable polymeric adhesive layer that is in direct contact with the second co-extruded layer and a backing layer; and a co-extruded backing layer adhered to the adhesive layer. Also disclosed is a product such an auto part, a truck part, an auto or truck body panel, or a part or panel of a recreational vehicle having a Class A surface that can comprise or be produced from the multi-layer sheet.
摘要:
A slush molding process in which the moldable thermoplastic composition powder dosed to the mold is prepared by blending ethylene carboxylic acid copolymers or ionomers with ethylene/glycidyl acrylate or methacrylate copolymer and cross-linking promoter at a temperature and for a time that does not cause significant cross-linking prior to dosing to mold, which is held for sufficient time and temperature to cause cross-linking in-situ, and optionally, other additives including release agents.
