Abstract: The present invention relates to a blow molded plastic container and to a polymer composition from which the blow molded plastic container is made. The blow molded plastic container comprises a pinched seamline and is made by an extrusion blow molding process comprising a pinch step. The present invention also relates to a gas storage tank, comprising the blow molded plastic container as a liner. The polymer composition comprises (a) a polyamide consisting of a copolyamide consisting of repeat units derived from lactam, diamine and dicarboxylic acid, and optionally chain stoppers or branching units or a combination thereof, or of a blend of at least two polyamides, comprising at least one polyamide comprising repeat units derived from lactam, and at least one polyamide comprising repeat units derived from diamine and dicarboxylic acid, and comprising 75-97.5 mole % caprolactam and 1-12 mole % monomer having an aromatic ring, (b) a heat stabilizer and (c) impact modifier.

Abstract: The invention relates to hybrid fabric comprising: a high-performance polyethylene (HPPE) fiber having a tensile modulus of at least 110 GPa, preferably higher than 135 GPa, as measured according to ASTM D885M-2014; and a non-polymeric fiber, wherein the cross-sectional area of the HPPE fiber is equal to or smaller than the cross-sectional area of the non-polymeric fiber, the cross-sectional area being defined as the linear density of the fiber divided by volumetric density of the fiber. The invention also relates to a composite comprising the hybrid fabric and to an article comprising the composite.
