Abstract: A resin composition excellent in impact resistance, rigidity and coatability properties, is easily moldable without causing voids and flow marks, and is suitable for the manufacture of automobile bumpers, which has a melt flow rate of not lower than 10 g/10 min. and which comprises:(A) 60 to 85 parts by weight of a crystalline propylene/ethylene block copolymer component having an ethylene unit content of 10 to 30 mole % and a melt flow rate of 10 to 30 g/10 min. (Comopnent A),(B) 5 to 20 parts by weight of an non-crystalline ethylene/alpha-olefin random copolymer component having an ethylene unit content of 60 to 85 mole %, a melt flow rate of 0.1 to 5.0 g/10 min and a crystallinity, measured by X-ray, of not more than 15% (Component B), and(C) 8 to 15 parts by weight of a talc or calcium carbonate component having an average particle size of 0.1 to 5 .mu. (Component C), in which values by the "parts by weight" are selected so as to amount to 100 parts by weight in total.

Abstract: A resin composition for injection molding, composed essentially of 100 parts by weight of a thermosetting resin such as phenolic resin or unsaturated polyester resin, 5-250 parts by weight of a salt of an oxyacid of phosphorus and 15-245 parts by weight of a filler which is preferably inorganic, on condition that the total amount of the oxyacid salt and the filler is in the range from 20 to 250 parts by weight. Preferably the oxyacid salt is a phosphate, especially a polyphosphate, expressed by MO.sub.m/2.nP.sub.2 O.sub.5, where M is a metal element including Si, m is the valence of the metal M, and n is in the range from 0.1 to 0.7, or an alkali metal salt of such a phosphate. This composition gives moldings that are very high in thermal stability. As a typical application, a fully practicable reflector for automobile head lamps is produced by providing a body molded by using this composition with a metal film by vacuum deposition.

Abstract: Flexible graphite granules prepared by a process comprising agitating vermiform expanded graphite masses having a bulk density of not more than 0.01 g/cc in a liquid have been found to be extremely suitable for producing a flexible graphite product, even with a low density, having an excellent shape-retaining property as well as a shapeability and exhibiting strong mechanical strengths.
