摘要:
A composition is disclosed that comprises an otherwise flammable flexible polyurethane foam and a multi-component flame retardant additive. The flame retardant additive includes an alkyl substituted aryl phosphate and an alkyl phosphate ester wherein the alkyl groups range from C4 to C20 and contain one to six oxygen atoms in the alkyl chain. Optionally, the flame retardant additive includes a halogenated flame retardant containing more than 30 wt. percent of bromine, chlorine, or a mixture thereof.
摘要:
Flame retardant flexible polyurethane foam compositions, methods of flame retarding flexible polyurethane foam compositions, articles made therefrom and flame retardants that comprise blends of tetrahalophthalate esters and phosphorus-containing flame retardant having at least about 5 wt. % phosphorus additives. The combined weight of the tetrahalophthalate ester and the phosphorus-containing flame retardant comprises about 5 to about 20% by weight of the flexible polyurethane foam compositions or reaction mixtures. The ratio of the tetrahalophthalate ester to the phosphorus-containing flame retardant is from about 80:20 to about 20:80 percent by weight and preferably from about 60:40 to about 40:60 percent by weight.

“A method of selecting a stream server to which to direct a content title includes (a) comparing a top-tier cache ease of entry for each of multiple of stream servers, (b) if one of the stream servers has a more favorable top-tier cache ease of entry than each of the other stream servers, selecting the one stream server with the more favorable top-tier cache ease of entry to which to direct the title, (c) if the top-tier cache ease of entry for all of the stream servers is equal, comparing a next-lower-tier cache ease of entry for each of the plurality of stream servers, and (d) if one of the plurality of stream servers has a more favorable next-lower-tier cache ease of entry than each of the other stream servers, selecting the one stream server with the more favorable next-lower-tier cache ease of entry to which to direct the title.”
摘要:
Flame retardants for polymer compositions which are mixtures including triaryl phosphate esters represented by the following formula: where R1-R15 can independently be located in the ortho, meta or para positions on their respective phenol rings and are, independently, H or branched or linear alkyl groups having 3 to 11 carbon atoms and the mole ratio of the alkylate to phenol in the mixtures is at least about 0.77, preferably greater than about 0.81, and most preferably greater than about 0.85. The higher alkylated mixtures of triaryl phosphate esters can be incorporated into polymer compositions alone or in combination with other flame retardants.
摘要:
A method for allocating content requests to a server pool includes directing a stream requesting a novel title to one of a least-busy server in a server pool and a least-miss-traffic server in the server pool; setting the server to which the novel title was directed to the requested title's preferred server; directing a stream requesting a familiar title to the title's preferred server; and directing a stream requesting a crowded title to one of a least-busy server and the least-miss-traffic server.
