摘要:
The present invention relates to phosphorous based flame retardants useful in polyurethane foam and foams comprising the phosphorous based flame and retardants.
摘要:
A method for flame-retarding styrenic resins is disclosed wherein the method comprises incorporating in compositions an effective amount of at least one flame retardant compound comprising both aliphatic and aromatic bromine.
摘要:
The invention is a flame retardant for styrene foams. The flame retardant contains both aromatic bromine and an olefin. The olefin is an internal olefin. Desirable flame retardants are selected from: formula (I): wherein R1 is C1-C6 and optionally containing a heteroatom or olefin; R2 is C1-C6 and optionally containing a heteroatom or olefin; and R3-R12 is H, C1-C6 (optionally containing a heteroatom), or halogen; and further wherein the compound of formula (I) is present in a concentration of at least 50 percent of a trans isomer; formula (II): wherein R1 is Halogen, C1-C6 and optionally containing a heteroatom or olefin; R2 is Halogen, C1-C6 and optionally containing a heteroatom or olefin; and R3-R7 is H, C1-C6 (optionally containing a heteroatom), or halogen; and formula (III): wherein R1 is Halogen, C1-C6 and optionally containing a heteroatom or olefin; R2 is Halogen, H, C1-C6 and optionally containing a heteroatom or olefin; and R3-R6 is H, halogen.
摘要:
A flame retardant blend comprises the following components: (a) at least one diester diol of a ring-brominated aromatic compound; (b) at least one alkylated triphenylphosphate; and (c) at least one hindered phenolic anti-oxidant in which the phenolic ring is substituted by at least one alkanoic alkyl ester group in which the alkanoic acid moiety has from about 2 to about 4 carbon atoms and the alkyl group has about 6 to about 16 carbon atoms. The proportions by weight of components (a) and (b) in the blend are in the range of about 30:70 to about 70:30 and the proportion by weight of component (c) to the sum of components (a) and (b) is in the range of about 0.1 : 100 to 1 : 100.
