  • Publication number: 20220403166
    Abstract: A composition including a compatibilized blend of polyamide, polyphenylene ether and a flameproofing agent that synergistically interact such that plaques produced from the composition pass a glow wire ignition temperature test (GWIT) without producing a flame. Advantageously, the flameproofing agent is non-halogenated and the compositions also free of other halogen containing components. In addition, the compositions are free of fillers and are unexpectedly still able to pass the noted tests.

  • Patent number: 9856365
    Abstract: The present invention relates to a thermoplastic composition that provides improved thermal aging stability along with durability. The thermoplastic composition comprises a polyamide resin, and a polyhydric alcohol, wherein a majority of the polyhydric alcohol particles have a particle size that is less than about 70 microns. It has been found that a combination of a polyamide resin and a polyhydric alcohol with this particle size produces a superior product demonstrating greater thermal stability and durability than the polyamide resin alone.

  • Patent number: 7534374
    Abstract: A composition containing particular amounts of a poly(arylene ether), a poly(arylene sulfide), an electrically conductive carbon black, and glass fibers is particularly useful for molding heat-resistant articles suitable for electrostatic painting. Compared to a corresponding composition without the poly(arylene ether), the composition exhibits improved paint attraction and markedly improved paint adhesion, and it allows the use of a lower level of conductive carbon black to achieve the same electrical conductivity. The composition thus provides an excellent balance of impact strength, electrical conductivity, and paint attraction and adhesion.
