  • Flame retardant thermoplastic elastomer composition with resistance to scratch-whitening
    Patent number: 8598298
    Abstract: Halogen-free, flame-retardant thermoplastic polyester elastomer (TPE-E) compositions that include at least one thermoplastic polyester elastomer, at least one low-melting, phosphorus-based flame retardant having a melting temperature no higher than 150° C., and a blend of solid intumescent flame retardants comprising a phosphorus-based, organic salt flame retardant and a nitrogen-based organic flame retardant are provided. The presence of the low-melting, phosphorus-based flame retardant renders the compositions more resistant to scratch-whitening.

  • COMPOSITIONS FOR THIN CIRCUIT MATERIALS, CIRCUITS, MULTI-LAYER CIRCUITS, AND METHODS OF MANUFACTURE THEREOF
    Publication number: 20080200084
    Abstract: A composition for the manufacture of a circuit material comprises a solvent composition having a boiling point below 160° C.; an epoxy compound having an average epoxy functionality of greater than one, an epoxy equivalent weight of less than about 6,000 Daltons, a softening point of less than about 160° C., and solubility in the solvent composition; an aromatic polymer co-curable with the epoxy compound, and soluble in the solvent composition; and, optionally, a catalyst for the polymerization of epoxy groups. The composition for the manufacture of a circuit material can further comprise a filler additive and/or a flame retardant additive.
