Abstract: A pneumatic tire includes a single carcass ply and at least one belt ply disposed radially outward of the carcass ply in a crown portion of the pneumatic tire. The carcass ply includes only one type of composite cord. The cord consists of one single aramid first yarn twisted helically about one single polyester second yarn. The first yarn and the second yarn have a different moduli of elasticity. The first yarn has a modulus greater than the modulus of the second yarn.

Abstract: The present invention pertains to a fibrous cord comprising yarns twisted together wherein the cord has a twist multiplier of from 5.0 to 12.0, and comprises a blend of aromatic polyamide or aromatic copolyamide yarns and polyester yarns. The invention further pertains to a composite layer comprising an elastomer and a fabric wherein the fabric comprises from about 25 to 60 weight percent of the total composite layer, and comprises a plurality of inventive cords.

Abstract: The present invention relates to a method of making polyacetal compositions and molded articles of these, which comprise at least one mineral filler that has not been previously coated before being mixed into the compositions.

Abstract: A semiaromatic polyamide composite article comprising a first component comprising a fiber-reinforced material comprising a polyamide composition and reinforcing fibers and having a tensile modulus of at least about 16 GPa as measured by ISO method 527-2:1993 at a rate of 5 mm/min on test specimens having a thickness of 4 mm, a second component comprising a polyamide composition, and an optional tie layer therebetween. The polyamide composition of first component and/or the second component is a semiaromatic polyamide compositions. The second component is prepared by injection molding and/or injection-compression molding the semiaromatic polyamide composition onto the first component.

Abstract: Thermoplastic compositions which are painted (coated) have improved adhesion to the paint when these compositions comprise a hydrophilic polyether or polyester modified siloxane. These thermoplastic compositions are particularly suited for use with aqueous based paints, in uses such as automobile and appliance bodies and parts.

Abstract: The invention relates to polyacetal compositions comprising a mixture of (i) a polyacetal resin, (ii) p-aramid particles and (III) a vinyl-terminated dimethyl siloxane polymer. These compositions are useful in preparing molded articles exhibiting a good balance between high self-lubricating properties and wear resistance, and especially useful in articles that are in motion with respect to other parts they are in contact with.

Abstract: The present invention relates to a method of making polyacetal compositions and molded articles of these, which comprise at least one mineral filler that has not been previously coated before being mixed into the compositions.

Abstract: The present invention relates to a process for coating substrates assembled from at least one polymeric part, with visible polymeric surfaces, comprising successive steps of applying and curing at least one coating on the visible surfaces of the substrate. The polymeric parts comprise a polyamide composition comprising polyamide, novolac resin, and toughener. The polyamide compositions may further comprise mineral fillers, nucleating agents, and other additives. Articles coated according to the process herein are also disclosed.

Abstract: Thermoplastic compositions containing certain salts of fluorinated sulfonic acids adhere especially well to coatings (paints) applied to the surface(s) of that composition. Useful parts that can be made include painted automotive body parts, appliance cases, and other parts with painted aesthetically pleasing surfaces.

Abstract: The invention relates to polyacetal compositions comprising (i) a polyacetal resin, (ii) p-aramid particles and (III) a vinyl-terminated dimethyl siloxane polymer and molded products thereof showing improved tribological properties.

Abstract: The invention relates to molded thermoplastic articles consisting of: a thermoplastic resin overmolded on a support screen, which support screen has indentations/protuberances.
