  • FLAME RETARDANT POLYAMIDE COMPOSITIONS WITH IMPROVED GLOW WIRE PERFORMANCE
    Publication number: 20240117157
    Abstract: A flame retardant polyamide composition comprising a polyamide, a non-halogenated, phosphinate-based flame retardant, an impact modifier comprising an alkene/acrylate copolymer/terpolymer, a flame retardant synergist and an optional reinforcing agent. The flame retardant polyamide composition demonstrates a passing value for a glow wire end product test as measured by IEC 60695-2-11, a passing value for a glow wire ignition test as measured by IEC-60695-2-13:201; a passing value (V0 rating) for UL94 performance at 0.8 mm; and an elongation at break greater than 2.7%, as measured by to ISO Test No. 527:2012.

  • Article Comprising a Polyolefin Substrate and a Layer Coating at Least a Portion of the Surface of the Said Polyolefin Substrate, and Process and Use
    Publication number: 20070293628
    Abstract: Article comprising at least one substrate (S) comprising at least one polyolefin composition (C1) comprising at least one nonfunctionalized polyolefin (PO1), the said substrate comprising a surface, and at least one layer (?) coating at least a portion of the surface of the said substrate, the said layer (?) being composed of at least one polyolefin composition (C2) comprising at least one functionalized polyolefin (POg) obtained by grafting acid and/or anhydride groups to at least one nonfunctionalized polyolefin (PO2), the acid and/or anhydride groups optionally being neutralized in all or in part by at least one neutralizing agent, and at least one emulsifying agent. Process for the manufacture of such an article. Improvement in the antistatic properties of the substrate (S) by means of the layer (?).
