REINFORCED AROMATIC POLYCARBONATE RESIN SHEET OR FILM |
| 摘要 |
Provided is an aromatic polycarbonate resin sheet/film which has excellent bending characteristics and surface smoothness. It is found that a sheet having excellent surface smoothness, which cannot be achieved by conventional sheets, can be obtained by adjusting sheet extrusion conditions for a polycarbonate resin sheet/film into which a reinforcing filler is blended. It is also found that a thermally shaped article having excellent appearance can be obtained by using this sheet in pressure molding or in thermal press molding. |

1. A reinforced aromatic polycarbonate resin sheet or film with a thickness of 0.2-1.5 mm comprising: a resin component containing (A) 40-80 pts. mass of an aromatic polycarbonate; and (C) 20-60 pts. mass of a reinforcing filling material containing at least one selected from (c-1) a fibrous filler and (c-2) a plate-like filler, where the total of (A) the aromatic polycarbonate and (C) the reinforcing filling material is 100 pts. mass,
wherein an arithmetic mean surface roughness (Ra) of at least one surface is 2.0 μm or less. |
