Abstract:
A fire retardant, reinforced composition comprising;a blend of polyphenylene ether resins comprising a Component A and a Component B, wherein Component A comprises a polyphenylene ether resin having an intrinsic viscosity of at least 0.3 dl/g, as measured in chloroform at 25Â° C., and Component B comprises a polyphenylene ether resin having an intrinsic viscosity of less than 0.25 dl/g, as measured in chloroform at 25Â° C., which is recovered from a reaction solution as a solid mass and granulated or pelletized to a desired size or is recovered from a reaction solution as an agglomerate with an average particle size greater than 100 &mgr;m; a flame retardant in an amount of 7% to 20% by weight of the composition; and about 3% to 30% by weight of glass fiber, based on the total weight of the entire composition, wherein the composition exhibits a UL-94 VO rating and an HDT value greater than about 139Â° C., as determined by ASTM D648.
