The present invention relates to compositions containing flame retardant polycarbonate, which are suitable for producing flame-resistant milk-white colored plates. The composition contains polycarbonate, 0.10 to 4.00 weight percent of an acrylate-based scattering additive, 0.50 to 5.00 weight percent of an aromatic-aliphatic polyester, and 0.50 to 8.00 weight percent of a phosphorus-based flame retardant.

Polycarbonate composition having improved flame resistance for extrusion applications

A sheet containing a base layer containing polycarbonate and a flame retardant,  

Polycarbonate plates with improved flame resistance

Disclosed is a composition comprising polycarbonate and from 0.0001 weight % to 0.1000 weight % of 2-(2,4-dihydroxy)phenyl-4,6-di(4-phenyl)phenyl-1,3,5-triazine.

Polycarbonate compositions with phenolically substituted triazine derivative

Battery box comprising compositions containing A) 70.0 to 90.0 parts by weight of linear and/or branched aromatic polycarbonate and/or aromatic polyester carbonate, B) 6.0 to 15.0 parts by weight of at least one graft polymer, C) 2.0 to 15.0 parts by weight of one or more phosphorus compounds, D) 0 to 3.0 parts by weight of antidripping agents, E) 0 to 3.0 parts by weight of thermoplastic vinyl (co)polymer (E.1) and/or polyalkylene terephthalate (E.2), and F) 0 to 20.0 parts by weight of further additives, wherein the compositions are optionally free from rubber-free polyalkyl(alkyl)acrylate.

Flame-retardant impact-modified battery boxes based on polycarbonate I

The present invention concerns a process for producing a container having at least one layer and a top layer, wherein the layer contains polycarbonate and the top layer contains polyarylethersulfone or polyarylsulfone, characterised in that a) polycarbonate is melted on an extruder at 230-320&#xb0; C., b) polyarylethersulfone or polyarylsulfone is melted on a further extruder, c) the melts obtained from steps a) and b) are shaped by coextrusion into a tube, which is then enclosed in a mould, d) the extrudate is inflated inside the mould and pressed against the wall of the mould, forming the shape of the container, and e) the container obtained from d) is trimmed and cooled, such containers and the use of the containers as bottles or medical devices.

Method for the production of multilayer containers

A solid sheet comprising transparent polycarbonate matrix, particles of a transparent polymer and an antistatic agent is disclosed. Characterized in that the refractive index of said matrix differs from that of said polymer, the sheet is suitable in making diffuser plate in flat screens.

Light-scattering sheet having high light transmission and improved antistatic properties

A multi-layer article is disclosed. The article contains a base layer that contains at least one thermoplastic resin and a second layer containing a thermoplastic (co)polyformal superimposed over the base layer. The (co)polyformal conforms to formulae (1) or (1), in which O-D-O and O-E-O independently denote a diphenolate group, -D- and -E- independently denote an aromatic group having 6 to 40 carbon atoms, k is a whole number from 1 to 1500, o stands for numbers from 1 to 1500, and m is z/o and n is (o-z)/o wherein z is 0 to o.

Polyformals as a coextrusion protective layer on polycarbonate

A thermoplastic compositions containing polycarbonate and a UV absorbing compound conforming to Formula 1 wherein R denotes a branched or unbranched alkyl group with 4 to 10 carbon atoms is disclosed. The composition is suitable for making molded or extruded articles, including multilayered articles exhibiting improved weatherability.

Compositions containing polycarbonate and novel UV absorbers

The present invention relates to a solid sheet prepared from a composition that includes: (a) a transparent polycarbonate; and (b) transparent polymeric particles having an optical density which differs from the transparent polycarbonate matrix material. The present invention also relates to use of such a solid sheet as a diffuser sheet in flat screens.

Light-scattering shaped articles of high light transmission and the use thereof in flat screens

A transparent sheet having improved optical properties is disclosed. The sheet that features a deviation angle &#x3b1;(min) according to DIN 52305-A-AS of &#x2266;2.0 and a refracting power D(min) according to DIN 52305-A-AZ of &#x2266;0.05, is prepared by extruding a molding composition comprising linear (co)polycarbonate having weight average molecular weight of 25,000 to 31,000.
