Abstract: A swimming pool wall, and method for forming same, including a plurality of layers of reinforced composite material. Each layer includes a thermoplastic resin and a plurality of elongate glass strands of reinforcing material. A first set of the plurality of layers has the strands miming in a first direction, and a second set of the plurality of layers has the strands miming in a second direction. The first direction is offset in angle from the second direction, and the first and second set of layers are fused together to form a unitary composite wall. The principles of hoop strength applicable to the swimming pool wall also apply to other cylindrical structures needing hoop strength arising from pressures inside or outside the cylindrical structure. The wall structure may be a plurality of interconnected panels both arcuate and arcuate and planar in shape to determine the overall shape of the composite wall enclosing an area where water or ice is retained.

Abstract: Thermoplastic compounds include elastomer, modified polyolefin polymer including a polar functional group, and unmodified polyolefin polymer. The melt flow rate of the modified polyolefin polymer is greater than the melt flow rate of the unmodified polyolefin polymer. The thermoplastic compounds exhibit excellent bonding when overmolded onto rigid substrates such as metals, while also providing desirable aesthetic properties and good processability.

Abstract: A preform is made by mixing cyclic olefin copolymer (COC) and light shielding pigment(s) with PET. The preform is stretch-blow moulded to produce a bottle which may be white and opaque. Light may be restricted from entering the bottle to thereby restrict degradation of the bottle contents from certain wavelengths of visible light.

Abstract: Resiliently flexible articles include a resiliently flexible element, a first rigid element, and a second rigid element. The resiliently flexible element is formed of a fiber reinforced polymeric composite. The first rigid element is formed of a first thermoplastic composition and at least a portion of the first rigid element is bonded, such as by an overmolding process, onto a first portion of the resiliently flexible element. Similarly, the second rigid element is formed of a second thermoplastic composition and at least a portion of the second rigid element is bonded, such as by an overmolding process, onto a second portion of the resiliently flexible element. The resiliently flexible articles can be useful as springs, limbs, living hinges, and the like.

Abstract: Lubricious thermoplastic articles are formed from thermoplastic compounds including (a) thermoplastic elastomer selected from thermoplastic polyurethane, polyether block amide, and combinations thereof; and (b) from about 5 to about 20 weight percent, by weight of the compound, of hydrophilic water-insoluble polymer selected from polyolefin-polyoxyalkylene block copolymer, crosslinked polyvinylpyrrolidone, and combinations thereof. The thermoplastic compounds are capable of providing enhanced lubricity in the thermoplastic articles without significant degradation in mechanical properties such as elongation and tensile strength, as compared to thermoplastic articles formed from the neat thermoplastic elastomer and subjected to the same heat processing history.

Abstract: A continuous fiber reinforced thermoplastic (CFRTP) tape is disclosed, made of continuous, unidirectional glass fibers embedded in polyethylene terephthalate glycol modified (PETG) containing a polyphosphonate homopolymer non-halogenated flame retardant (NHFR). With formulations balancing the spread of flame and the detection of smoke, the tape achieves a Class A value when tested in accordance with ASTM E84.
