Patent number: 5401787Abstract: Improved flame retardant moisture curable insulation compositions are comprised of an ethylene-alkoxysilane copolymer, a halogenated anhydride and antimony trioxide provided. The compositions have good processability and can be moisture cured to provide products which meet all of the requirements for SAE J-1128 low tension primary cable. The halogenated anhydride imparts flame retardancy to the compositions and also promotes cure by catalyzing the hydrolysis/condensation reaction of the silane copolymer. Optionally there may be included in the composition antioxidants, silanol condensation catalysts, organic halogen containing flame retardant compounds and other conventional compounding ingredients.Type: GrantFiled: May 4, 1994Date of Patent: March 28, 1995Assignee: Quantum Chemical CorporationInventor: Koksal Tonyali

Patent number: 5393813Abstract: By adding melamine cyanurate, polyoxymethylene is stabilized against acid attack, wherein in particular as little as under 3 parts of MCA per 100 parts of POM are effective. The weight loss of a stabilized POM under the action of acid may be less than 3% of that of an unstabilized POM. The product is useful in products which are exposed to acidic agents such as irrigation systems, dishwashers, sanitary installations.Type: GrantFiled: October 22, 1993Date of Patent: February 28, 1995Assignee: Degussa AktiengesellschaftInventors: Stephanie Schauhoff, Edwin Nun, Detlef Arnoldi

Patent number: 5369157Abstract: Thermoplastic compositions containing, per 100 parts by weight of a thermoplastic material containing at least one alkenyl aromatic hydrocarbon polymer or copolymer and, if required, at least one other thermoplastic of elastomeric resin:(a) from 5 to 30 parts by weight of melamine and melamine isocyanurate,(b) from 2 to 10 parts by weight of at least one polyol containing at least 4 hydroxyl functions per molecule, and(c) from 0 to 14 parts by weight of at least one organic ester of phosphoric acid.A process for their preparation consists of mixing the various constituents at a temperature higher than the softening point of the alkenyl aromatic hydrocarbon polymer or copolymer, between 150.degree. and 200.degree. C., for a duration between 1 and 5 minutes in an internal mixer or extruder.Articles obtained by transformation of the above compositions are formed having low combustion rates.Type: GrantFiled: December 27, 1993Date of Patent: November 29, 1994Assignee: AtochemInventor: Rene Wirth
