Polypropylene polymer compositions are disclosed that can be used to produce different types of molded articles, such as extruded piping structures. The polypropylene polymer composition contains a polypropylene random copolymer in combination with a property enhancing agent. The property enhancing agent is incorporated into the polymer composition so that the composition has relatively high impact resistance properties in combination with a relatively high flexural modulus.

The present invention relates to fibre composite materials composed of a fibre material and an aromatic polycarbonate-based matrix material and to multilayer composite materials comprising one or more such layers of fibre composite material. The fibre composite material has a pleasing look with stripes that seem naturally formed on a white or coloured background. The fibre layer(s) is/are embedded in the matrix material. The present invention further relates to a process for producing the fibre composite materials and multilayer composite materials and to components, housing components or housings, especially for laptop, notebook or ultrabook covers, comprising such composite materials themselves.

A self-extinguishing resin molded body obtained from a resin composition containing a polyolefin resin (A), a phosphorus-based flame retardant (B), and a glass fiber (C), wherein the self-extinguishing resin molded body contains from 15 to 30 mass % of the phosphorus-based flame retardant (B) and from 5 to 50 mass % of the glass fiber (C); and the self-extinguishing resin molded body satisfies the following (I) to (III). (I) A thickness of the self-extinguishing resin molded body is from 1.5 to 8.0 mm. (II) The self-extinguishing resin molded body self-extinguishes within 2 minutes after the completion of a burning test using burning test method E as described below. (III) The self-extinguishing resin molded body does not have a hole after being subjected to a burning test using burning test method E as described below. Burning test method E: A plaque (150×150×2.0 mm) made of the molded body described above is used. A 200 mm-long flame is applied from above the plaque directly onto the center of the plaque for 130 seconds. The distance from the flame contact position on the plaque to the burner mouth is 150 mm.
