  • Patent number: 12281489
    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 running in a first direction, and a second set of the plurality of layers has the strands running 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 pool wall permits the use of a composite material which provides sufficient strength and resists degradation. 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.

  • Patent number: 12221539
    Abstract: Thermoplastic articles are molded from thermoplastic polyurethane compounds including blends of aliphatic polycaprolactone thermoplastic polyurethane and aromatic thermoplastic polyurethane selected from aromatic polyester thermoplastic polyurethane, aromatic polyether thermoplastic polyurethane, and combinations thereof. The thermoplastic articles exhibit enhanced stain resistance, as represented by achieving a rating of 2 or better according to Blue Jean Abrasion Test, relative to thermoplastic articles molded from thermoplastic polyurethane compounds including either aromatic polyester thermoplastic polyurethane or aromatic polyether thermoplastic only, while also having good clarity (i.e., low haze) and other desirable properties. The thermoplastic articles can be especially useful as protective cases for handheld electronic devices.

  • Patent number: 11917802
    Abstract: Thermoplastic compounds in the form of a pellet include thermoplastic resin and conductive fibers. The conductive fibers are enveloped by the thermoplastic resin and distributed within the pellet such that each of at least a portion of the conductive fibers is substantially surrounded by the thermoplastic resin and thereby substantially separated from physical contact with any other of the conductive fibers. Additionally, at least a portion of the conductive fibers includes long fibers. The thermoplastic compound, when molded at a thickness of about 3.2 mm, has an electromagnetic shielding effectiveness across a range of frequencies from about 0.5 GHz to about 2.0 GHz of at least about 60 dB according to ASTM D4935, which makes the thermoplastic compound useful for molding thermoplastic articles for shielding against electromagnetic interference.
