The present invention relates to a flame-retardant polycarbonate composition comprising the following components, relative to the total weight of the composition: A) 30-70 wt. % of at least one aromatic polycarbonate, B) 20-60 wt. % of at least one polysiloxane-polycarbonate block condensate, C) 0.5-5 wt. % of at least one cyclic phosphazene, D) 1-5 wt. % of at least one silicone-acrylate rubber based impact modifier, E) 0.3-3 wt % of kaolin, F) 0.1-1 wt. % of at least one anti-dripping agent, and G) 0.1-1 wt. % of at least one UV absorber. The present invention also relates to a shaped article produced from the composition. The polycarbonate composition according to the present invention has a good combination of low-temperature impact performance, flame-retardancy, hydrolytic stability, anti-UV performance, and heat resistance.

An anti-friction lacquer has a resin matrix of a polymer and functional fillers containing mixed-phase oxides having a specified grinding hardness and proportion and optionally contain further functional fillers. A sliding element is also disclosed having a metallic substrate layer and a coating applied to the substrate that is made of at least in part of the anti-friction.

The present invention discloses a polypropylene composition. A resin matrix is composed of copolymerized polypropylene and branched polyethylene with special parameters, such that the resin matrix has a low crystallization tendency, thereby improving spraying adhesion of a surface of the resin matrix. A polyolefin elastomer (POE) in bimodal distribution is further used to improve the appearance after molding.
