Abstract
Described herein is a polyamide composition comprising two polyamides and glass fiber, wherein one of the polyamides is a polyphthalamide formed by polycondensation from various monomers: dicarboxylic acid(s) with diamine(s) and/or amino acid(s), wherein at least one monomer contains a cyclohexyl group. It was surprisingly discovered that the polyamide composition has improved warpage and/or mold shrinkage properties, excellent mechanical performance and high Tg and/or Tm. Due to the excellent performance, the polyamide composition is suitable for molding and can be desirably incorporated into mobile electronic device applications.
