A polymer composition is disclosed containing a coupling agent and an impact modifier that renders the composition resistant to ultraviolet light degradation. The polymer composition contains an aliphatic coupling agent, an aliphatic impact modifier, or both an aliphatic coupling agent and an aliphatic impact modifier. The polymer composition is well suited to producing molded articles, especially articles that will later be exposed to substantial amounts of ultraviolet light. For example, molded articles made according to the present disclosure are well suited for use on the interior of vehicles where the parts are not only exposed to ultraviolet light, but are also exposed to repeated thermal cycles.

Impact modified polyoxymethylene composition and articles made therefrom that are stable when exposed to ultraviolet light

The present disclosure relates to a molding composition and to molded products made from the composition. In accordance with the present disclosure, the polymer composition contains a polyoxymethylene copolymer having a relatively low amount of comonomer units. The polyoxymethylene polymer is combined with at least one reinforcing fiber and a coupling agent. The above polymer produces a composition have a relatively high heat deflection temperature, while also having excellent mechanical properties.

Fiber reinforced polyoxymethylene composition with improved thermal properties

The present invention relates to a method for the manufacturing of a container or parts of a container for fuel or compressed gases by extrusion blow molding and container or parts of container for fuel or compressed gases made thereof.

High impact resistant polyoxymethylene for extrusion blow molding

VOC or compressed gas containment devices, such as polymer fuel tanks, are made from a polyoxymethylene polymer composition. The polymer composition contains a polyoxymethylene polymer that is directly or indirectly chemically attached to an impact modifier. In one embodiment, for instance, a coupling agent bonds the impact modifier to the polyoxymethylene polymer. In order to preserve the permeability of the polymer material when combined with the impact modifier, a polyoxymethylene polymer is used that contains a low level of low molecular weight constituents.

VOC or compressed gas containment device made from a polyoxymethylene polymer

Composites are described, comprising polyacetal and at least one thermoplastic polyamide elastomer formed by a polyacetal molding which has been partially or completely coated with the thermoplastic polyamide elastomer or onto which one or more moldings composed of the thermoplastic polyamide elastomer have been directly molded. The composites are characterized in that the polyacetal and the thermoplastic polyamide elastomer have been bonded adhesively or cohesively to one another via injection of the polyamide elastomer onto the polyacetal molding, and in that the tensile bond strength between the polyacetal and the thermoplastic polyamide elastomer is at least 0.5 N/mm. The composites may be used as connectors, as functional components with integrated sealing properties and/or with integrated damping properties, or else as non-slip and easy-grip elements.

Composite bodies, method for the production thereof and use thereof

Composite bodies, processes for making them, and their uses are disclosed, the composite bodies comprising a polyacetal portion and a modified thermoplastic vulcanizate portion bonded together, wherein the modified thermoplastic vulcanizate portion comprises a modified thermoplastic vulcanizate elastomer having a hardness of 30 to 90 Shore A and wherein the modified thermoplastic vulcanizate elastomer comprises: (a) 2 to 75% by weight of an at least partially crosslinked ethylene-propylene-diene rubber in from 1 to 50% by weight of a polyolefinic matrix further comprising 0.05 to 10% by weight of an ingredient selected from the group consisting of stabilizers, crosslinking aids, and mixtures thereof; (b) 1 to 30% by weight of a compatibilizer; and (c) 10 to 70% by weight of a non-olefinic thermoplastic material, all percentages by weight based on a total weight of the modified thermoplastic vulcanizate elastomer.

Composite bodies having a polyacetal portion and a thermoplastic vulcanized elastomer portion, processes for making the same, articles including such bodies and uses therefor

Composite products are described and encompass at least one polyacetal molding and at least one polyolefin molding, which have been bonded at at least one of their surfaces using an adhesion-promoting layer which is substantially composed of a copolymer or of a mixture of these which derives from at least one alpha-olefin and from at least one ethylenically unsaturated carboxylic acid, and/or from at least one ethylenically unsaturated carboxylic acid derivative, where the molar ratio of alpha-olefin to ethylenically unsaturated carboxylic acid and/or to ethylenically unsaturated carboxylic acid derivative is selected so as to obtain composites with a bond strength (measured by the tensile test at 23&#xb0; C.) of at least 0.2 N/mm. The composite products described can in particular be used for producing components which come into contact with fuels.

Composite body made from polyacetal, bonding agent and polyolefin, method for production and use thereof

Polyoxymethylene with improved resistance to acids, comprising This polyoxymethylene is particularly advantageous when used for producing moldings for use in contact with aggressive acids or with aggressive acid-containing cleaning agents, in particular for applications in the sanitary sector or the white goods sector.

Polyoxymethylene with improved resistance to acids and its use

Process for producing a composite article from a polyacetal (component a) with directly molded-on functional elements made from one or more thermoplastic elastomers (component b), and wherein components a and b have differing hardness, and the material with the greater hardness (component a) is initially premolded in a first step in a mold, and then is either cooled and removed from the mold and then placed into another, larger cavity, or is partially removed from the mold, but remains in a portion of the mold, and is then moved to a larger cavity, or, without removal from the mold, remains in the same mold, which is enlarged by means of a movable device, and in a second step, by overmolding with the material with the lesser hardness (component b), the molding formed from component a is firmly bonded to this material and is then removed from the mold as a composite article.
