  • Publication number: 20230036408
    Abstract: This invention relates to a synergistic combination of molybdate salts (e.g., calcium molybdate) and magnesium hydroxide to suppress both smoke and flame in polymeric compositions, such as plastic piping, profile applications, wire and cable, semiconductor and electrical conduit application, to name a few. In some embodiments, the technology relates to polyvinyl chloride (“PVC”) and chlorinated polyvinyl chloride (“CPVC”) compounds, among other polymer resin containing compounds, having improved smoke and flame performance from the synergistic combination of molybdate salts and magnesium hydroxide.

  • Publication number: 20220227985
    Abstract: The disclosed technology relates to a plastic compound suitable for preparing articles, such as pipe, with good physical properties, such as impact strength, and resistance to environmental stress cracking (ESC). In particular, the technology relates to a vinyl chloride resin, which includes chlorinated polyvinyl chloride (“CPVC”) homopolymer. Furthermore, the invention relates to vinyl chloride homopolymer compounds containing the vinyl chloride homopolymer resin, and articles made from such compounds, which compounds meet 23447 cell classifications under ASTM D1784.

  • Publication number: 20090159134
    Abstract: A system for distributing water within a building operates to distribute water from a pressurized water supply source to devices that receive water, such as faucets, toilets, showers, sprinklers, and hot water heating devices. The system includes at least one manifold which may be of unitary molded plastic construction and comprised of chlorinated polyvinyl chloride (CPVC). The manifold includes an entry port and a plurality of outlet ports which are also referred to as sockets. The sockets are configured to receive fitting inserts of various types that include water line connectors. The sockets are also configured to accept standard plastic water conduits therein in cemented relation. The water line connectors may include metallic connectors such as barbed fittings, which can be used to connect the manifold and crosslinked polyethylene (PEX) pipe in nonthreaded relation. Manifolds may be connected together to provide suitable distribution arrangements.
