  • Flame-retardant poly(arylene ether) composition and its use as a covering for coated wire
    Patent number: 8278376
    Abstract: A flame retardant poly(arylene ether) composition is described. In addition to the poly(arylene ether), the composition includes a polyolefin component, and a flame retardant composition that includes a metal dialkyl phosphinate. The polyolefin component can be a polyolefin polymer and/or the polyolefin block of a poly(alkenyl aromatic)-polyolefin block copolymer. The composition is particularly suitable as a replacement for poly(vinyl chloride) in insulation for wire and cable.

  • Flame-retardant poly(arylene ether) composition and its use as a covering for coated wire
    Patent number: 7655714
    Abstract: A flame retardant poly(arylene ether) composition is described. In addition to the poly(arylene ether), the composition includes a polyolefin component, and a flame retardant composition that includes a metal dialkyl phosphinate and a nitrogen-containing flame retardant but excludes a liquid triaryl phosphate. The polyolefin component can be a polyolefin polymer and/or the polyolefin block of a poly(alkenyl aromatic)-polyolefin block copolymer. The composition is particularly suitable as a replacement for poly(vinyl chloride) in insulation for wire and cable.
