Abstract:
1. A polymer composition comprising: (a.) 90 to 40 wt % of at least one semi-aromatic polyamide; (b.) 10 to 60 wt % of at least one aliphatic polyamide; (c.1) at least one white pigment; and (c.2) optionally at least one secondary component, wherein the sum of the amount of the at least one semi-aromatic polyamide and the at least one aliphatic polyamide is 100 wt % and the at least one white pigment is present in an amount of at least 10 wt. %, calculated based on the total weight of the composition, and wherein: (i.) the semi-aromatic polyamide is derived from one or more aliphatic diamine monomers containing 4 to 12 carbon atoms and one or more benzene dicarboxylic acid monomers; (ii.) the aliphatic polyamide is derived from one or more aliphatic diamine monomers containing 4 to 10 carbon atoms and one or more aliphatic dicarboxylic acids with 6 to 12 carbon atoms; and (iii.) the diamine in the at least one semi-aromatic polyamide comprises diamino butane.
