  • Flame retardant wood plastic composite
    Patent number: 9790349
    Abstract: A wood plastic composite comprises a thermoplastic resin, a lignocellulosic filler, a flame retardant material in an amount of between 10 to 20 percent by weight, based on the total weight of the composite, and optionally other additives, wherein the flame retardant material comprises one or more compounds selected from the group of a cyclic organophosphorous compound and mixtures of the cyclic organophosphorous compound together with a nitrogen-containing organic compound, and optionally a minor amount of an inorganic flame retardant.
    Type: Grant
    Filed: November 14, 2014
    Date of Patent: October 17, 2017
    Inventors: N. Matthias Neisius, Ingmar E. Held, Mike Mikolay, Zoran Bdraski, Neal Kendall, Hollie Kennedy
  • Phosphonamidates-synthesis and flame retardant applications
    Patent number: 9650497
    Abstract: A group of novel compounds containing one or more amino substituted DOPO (9,10-dihydro-9-oxa-phosphaphenthren-10-oxide) moieties. The compounds were found to have good flame retardant properties and also good thermal stability, which makes them particularly suitable as flame retardant additives for various thermoplastic polymers. In particular, they can be incorporated in a polyurethane foam.
