Pultrusion processes for producing fiber reinforced polyurethane composites are described. The processes utilize a polyurethane-forming reaction mixture comprises a chelated organometallic/metalorganic catalyst. Polyurethane-forming reaction mixtures suitable for use in such processes are also described.

Pultrusion processes for producing fiber reinforced polyurethane compositions and polyurethane-forming reaction mixtures suitable for use in such processes

Disclosed are processes for producing molded polyurethane elastomers and products, such as filter end caps, that include such elastomers. The elastomers are the reaction product of a non-foaming reaction mixture comprising an isocyanate-reactive composition and an organic polyisocyanate prepolymer with an internal mold release agent.

Processes for producing filter cartridge assemblies and molded polyurethane elastomers

A transaction card assembly may be constructed and arranged for use in a transaction by an issuee of the transaction card assembly. The transaction card assembly may include a first layer including a sheet of material, a second layer including a sheet of material, and an adhesive foam material between the first and second layers that expands to fill a space between the first and second layers and to define, at least in part, a finished thickness for the transaction card assembly and bonds the first and second layers together. Indicia, such as information representing an account number, biometric data representing a feature of the issuee, etc., may be included with the assembly for use in a transaction.

Transaction card assembly and methods of manufacture

The present invention is directed to a method of forming a gasket around a substrate from a novel polyurethane/urea composition via the RIM process. Window gaskets may be produced by this method. These novel polyurethane/urea compositions comprise the reaction product of a (cyclo)aliphatic polyisocyanate having a viscosity of less than about 25,000 mPa.multidot.s at 25.degree. C. and a NCO functionality of 2.0 to 4.0 with an isocyanate-reactive component comprising b1) a relatively high molecular weight organic compound containing hydroxyl groups, amine groups, or mixtures thereof; and b2) a low molecular weight chain extender selected from the group consisting of diols, primary amines, secondary amines, aminoalcohols, and mixtures thereof; in the presence of a catalyst. The isocyanate and isocyanate-reactive components are selected such that the crosslinking density of the resultant polyurethane/urea composition is at least 0.3 moles/kg. It is also possible that the isocyanate-reactive component comprises b3) a low molecular weight chain terminator, and/or b4) a low molecular weight crosslinking agent. When either or both of these components are included in the isocyanate-reactive component, A, b1), b2), and/or b3) and/or b4) must be selected such that the crosslinking density of the resultant polyurethane/urea composition is at least 0.3 moles/kg.

Method of producing gaskets from polyurethane/urea compositions and

The present invention is directed to polyurethane moldings produced via the RIM process. These polyurethane moldings have excellent reactivity, demold properties (at a 30s demold), and good elongation and tear strength, and comprise the reaction product of an HDI prepolymer having an NCO content of 5 to 25%, a functionality of less than 2.3, and a monomer content of less than 10%, with an isocyanate-reactive component comprising b1) at least one relatively high molecular weight organic compound containing at least about two isocyanate-reactive hydroxyl groups; b2) at least one relatively low molecular weight organic compound selected from the group consisting of diols, aminoalcohols, and mixtures thereof; and b3) at least one relatively low molecular weight hydroxyl-based crosslinking compound containing no more than one aliphatic amine hydrogen atoms capable of reacting with isocyanate groups; in the presence of at least one catalyst.
