1. A mobile telephone housing, comprising a polyamide composition comprising,
(A) about 20 to about 70 weight percent of at least one polyamide component comprising,
(a) about 60 to about 100 weight percent of at least one aliphatic polyamide selected from the group consisting of polyamide 10,10 and polyamide 10,12
(iii)(b) 0 to about 40 weight percent of at least one semiaromatic polyamide comprising about 60 to 100 mole percent of repeat units derived from one or more aromatic dicarboxylic acids; and (B) about 30 to about 65 weight percent of one or more reinforcing agents; and (C) 0 to about 20 weight percent of one or more impact modifiers;wherein the weight percentages of (a) and (b) are based on the total weight of (a)+(b) and the weight percentages of (A), (B), and (C) are based on the total weight of (A) (B) (C), and the composition has a tensile modulus greater than or equal to about 12 GPa, as measured by ISO 527-1/2 and a moisture absorption of less than or equal to about 0.25 weight percent, as measured by ISO 62. |
