  • 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.

  • Publication number: 20230228113
    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: 11697733
    Abstract: Thermoplastic articles are molded from thermoplastic polyurethane compounds including blends of aromatic polycaprolactone thermoplastic polyurethane and aliphatic polycaprolactone thermoplastic polyurethane. The thermoplastic articles can have enhanced stability against exposure to ultraviolet (UV) light relative to thermoplastic articles molded from thermoplastic polyurethane compounds including only aromatic polycaprolactone thermoplastic polyurethane as the thermoplastic polyurethane component. Additionally, the thermoplastic articles can have good stain resistance, good clarity (i.e., low haze), and other desirable properties.

  • Patent number: 11566122
    Abstract: A thermoplastic elastomer compound includes polyolefin elastomer, high softening point tackifier, and, optionally, styrenic block copolymer. When styrenic block copolymer is present, the weight ratio of polyolefin elastomer to styrenic block copolymer is no less than about 1:1. The polyolefin elastomer has a POE Tan Delta Peak Temperature, the styrenic block copolymer has a SBC Tan Delta Peak Temperature, and the thermoplastic elastomer compound has a Compound Tan Delta Peak Temperature. The Compound Tan Delta Peak Temperature is greater than the POE Tan Delta Peak Temperature. When styrenic block copolymer is present, Compound Tan Delta Peak Temperature is also greater than the SBC Tan Delta Peak Temperature. The thermoplastic elastomer compound exhibits useful damping properties at or above room temperature and can be formed into plastic articles, including foamed plastic articles and/or crosslinked plastic articles, which can be useful for a variety of damping applications.
