    Abstract: The present invention relates to advanced flame/fire retardant compositions for fabric, upholstery, carpet, barrier, automotive, building construction, communication, and consumer electronics applications. The flame retardant composition comprises: about 5-25 wt. % hydrogenated styrenic block copolymer, about 6-40 wt. % polyolefin, about 50-80 wt. % inorganic flame retardant, about 0-5 wt. % coating, about 0-5 wt. % functionalized styrenic block copolymer, about 0-7 wt. % agri-derived heat resistant liquid, about 0.05-1.0 wt. % antioxidant, and about 0-7 wt. % optional additives such as metal deactivator, colorant, filler, and/or lubricants, wherein said composition totals 100 wt. %. An article made from the flame retardant composition, such as film, fiber, cable, and wire insulation meets various European and U.S. standards. The flame retardant compositions possess a good balance of tensile strength, elongation, flame resistance, and processability that has previously been unobtainable.

    Abstract: Provided is a polyphenylene ether resin composition having excellent mechanical properties, such as tensile, flexural, and impact strength, high flame retardance, and adequate molding fluidity, and that is sufficiently resistant to use as a thin molded article for an electric/electronic device cooling fan, etc. The polyphenylene ether resin composition contains at least 90 mass % of a polyphenylene ether (A), a styrene resin (B), glass fiber (C), and an organophosphorus flame retardant (D) in terms of total mass of (A) to (D). Taking this total mass as 100 mass %, contents of the polyphenylene ether (A), styrene resin (B), glass fiber (C), and organophosphorus flame retardant (D) are 25-75 mass %, 0-5 mass %, 20-50 mass %, and 5-20 mass %, respectively, and taking mass of the organophosphorus flame retardant (D) as 100 mass %, content of at least one compound selected from the group consisting of triphenyl phosphate and a phosphazene is at least 70 mass %.
