MOLDED ARTICLE |
| 摘要 |
A molded article contains a methacrylic resin composition containing a methacrylic resin, and has a joining portion for being joined to a different member in at least part of the molded article, wherein a thickness t (mm) of the molded article excluding the joining portion and a resin flow length L (mm) of the molded article satisfy relationships of formulae (1) and (2) below:;t<4.0 (1);L/t>100 (2),the methacrylic resin composition has a melt mass-flow rate value a (g/10 min) and a melt mass-flow rate value b (g/10 min) which satisfy relationships of formulae (3) and (4) below:;5.0<b/a (3);0.3<a<15 (4);wherein the melt mass-flow rate value a is determined at a load of 3.80 kgf and a test temperature of 230° C., and the melt mass-flow rate value b is determined at a load of 10.19 kgf and a test temperature of 230° C. according to JIS K7210:1999. |

1. A molded article comprising a methacrylic resin composition comprising a methacrylic resin, and a joining portion for being joined to a different member in at least part of the molded article,
wherein a thickness t (mm) of the molded article excluding the joining portion and a resin flow length L (mm) of the molded article satisfy relationships expressed by formulae (1) and (2) below:
t<4.0 (1)L/t>100 (2), and the methacrylic resin composition has a melt mass-flow rate value a (g/10 min) and a melt mass-flow rate value b (g/10 min) which satisfy relationships expressed by formulae (3) and (4) below:
5.0<b/a (3)0.3<a<15 (4)wherein the melt mass-flow rate value a is determined at a load of 3.80 kgf and a test temperature of 230° C., and the melt mass-flow rate value b is determined at a load of 10.19 kgf and a test temperature of 230° C. according to JIS K7210:1999. |
