Abstract:
A composition comprising (A) at least one bisphenol-A polycarbonate resin, (B) at least one polypropylene, preferably a high crystallinity polypropylene, (C) at least one compatibilizer comprising an amine functionalized elastomeric polymer, (D) at least one organic phosphate flame retardant, preferably an organic phosphate that is liquid at room temperature, and, optionally, (E) one or more additives. These compositions are useful in the manufacture of wire insulation coatings of less than 0.2 mm with good scrape abrasion resistance.
Abstract:
Power cables intended for working under extreme conditions of heat and temperature are prone to deterioration and/or destruction of their protective layers, and it is therefore extremely important, for safety reasons, that said cables be made of fire-resistant materials, which are flame-retardant in the event of a fire. The present invention proposes obtaining a power and/or telecommunications cable which includes at least: an electric and/or optical conductor element, covered with at least one electrically insulating layer, also optionally including a protective layer surrounding one or more insulated conductor elements, having the special feature that the cover and/or insulation of the cable includes: a) an extrusible organic polymer or a mixture of several extrusible organic polymers; b) an inorganic phosphate arranged hierarchically on phyllosilicates; and c) other secondary inorganic fillers.
Abstract:
The present invention relates to flame retardant thermoplastic vulcanizate compositions having improved abrasion resistance and strip force. In addition, the invention relates to wire and cable coated with these compositions. The flame retardant thermoplastic vulcanizate compositions comprise a thermoplastic vulcanizate composition, at least one halogen-free flame retardant and an ultra-high molecular weight polysiloxane.
Abstract:
A graft copolymer capable of providing impact resistance, flame retardance, and color rendering properties to a thermoplastic resin is described. The graft copolymer contains a polyorganosiloxane, and is obtained by graft-polymerizing vinyl monomers including a (meth)acrylate ester (b 1 ) having an alkyl group or an aromatic group and an aromatic vinyl monomer (b 2 ) on a polyorganosiloxane-based rubber. The graft copolymer has a volume average particle diameter of 200-2000 nm, and contains 0.1-69 mass% of polyorganosiloxane. A thermoplastic resin composition is also described, containing a thermoplastic resin (A), the graft copolymer, a fluorine resin (C) and a flame retardant (D). A molded article is also described, which is obtained by molding the thermoplastic resin composition.
Abstract:
Disclosed herein are compositions including a cross-linked polycarbonate. The cross-linked polycarbonate may be derived from a polycarbonate having about 0.5 mol % to about 5 mol % endcap groups derived from a monohydroxybenzophenone. A plaque including the composition can achieve a UL94 5VA rating. Also disclosed herein are articles including the compositions, methods of using the compositions, and processes for preparing the compositions.
Abstract:
A vibration damping material according to one aspect of the present invention contains, as the main component, a composition which contains at least, in an external ratios, 0.01 to 15 parts by weight of an organic peroxide capable of crosslinking epoxy-type crosslinking points with each other, 25 to 50 parts by weight of carbon black having an average particle diameter of 22 to 45 nm and 15 to 35 parts by weight of carbon black having an average particle diameter of 70 to 85 nm in 100 parts by weight of an acrylic rubber, wherein crosslinking points in the acrylic rubber are crosslinked with each other through the organic peroxide.
Abstract:
The present invention is directed to provide at least one of a novel thermosetting resin composition using an epoxy compound, a method for producing the composition, a method for producing a novel cured resin using an epoxy compound, and a novel method for causing self-polymerization of an epoxy compound. The thermosetting resin composition includes an epoxy compound, a gallium compound, and a silanol source compound. The method for producing the thermosetting resin composition includes a step of mixing the epoxy compound with the gallium compound and the silanol source compound. The method for producing a cured resin includes a step of heating an epoxy compound in the presence of a gallium compound and silanol. The method for causing self-polymerization of an epoxy compound is characterized by using a gallium compound and silanol as catalysts.
