Described herein are polyphenylene sulfide ('PPS') polymer compositions including a low MFR PPS polymer and E-CR glass fibers. It was surprisingly discovered that the PPS polymer compositions had significantly improved retention of tensile strength and tensile elongation after water aging ('water aging performance'), relative to corresponding PPS polymer compositions having E glass fibers instead of the E-CR glass fibers. Moreover, it was also discovered that PPS polymer compositions including E-CR glass fibers in conjunction with a low MFR PPS polymer and a high MFR PPS polymer had unexpected synergies with respect to water aging performance, relative to corresponding polymer compositions including E-CR glass fibers and either a low MFR PPS polymer or a high MFR PPS. Due at least in part to the improved water aging performance, the PPS polymer compositions can be advantageously incorporated into application settings where the polymer composition is in contact with water. Examples include, but are not limited to, drinking water applications.

Overmolded inserts and methods for forming the same The present disclosure is directed to overmolded inserts () with reduced internal residual stress and corresponding methods for forming the overmolded inserts. The overmolded inserts have a polymer housing; metal or metal allow tapered insert () and a compression element () disposed between the housing and the distal end of the tapered insert. During formation, the tapered insert and compression element are placed within a mold. The polymer housing material is heated and filled into the mold. As the polymer housing cools, the compression element is compressed between the polymer housing and the tapered insert. The overmolded inserts formed have reduced internal residual stress relative to a corresponding insert formed from non-tapered insert.

A process for manufacturing a fuel tank including a thermoplastic wall and a fibrous reinforcement on at least one portion of its outer surface, according to which: a molten thermoplastic parison is molded in a mold and is left to cool in order to obtain a wall of the tank; a fibrous reinforcement is chosen that includes a thermoplastic similar to or compatible with that of the wall of the tank and the reinforcement is heated so as to soften or even melt the thermoplastic of the reinforcement; and the reinforcement is applied to an outer surface of the tank by exerting a force that makes it possible to weld the reinforcement and the outer surface.

Method for manufacturing a plastic fuel tank by moulding a parison in a mould, in which method the parison is locally deformed during moulding of the parison in order to obtain an impermeable hollow built-in connector provided with a screw thread, and to do so by means of a concave counter-form and a convex form that can penetrate the counter-form, these two pieces being secured, one to the mould and the other to a core located inside the mould, or vice versa, and at least one of these pieces being provided with a screw thread, the moulding of the connector taking place by the convex form penetrating the concave counter-form.
