The present invention can provide a polyamide composition that is more excellent in the heat resistance and tensile elongation of molded products and also more excellent in a balance between these properties than those given by conventional polyamide compositions. The present invention relates to a polyamide composition comprising polyamide (A), liquid-crystalline polyester (B), and non-liquid-crystalline polyester (C), characterized in that Ma part by mass of the polyamide (A), Mb part by mass of the liquid-crystalline polyester (B), and Mc part by mass of the non-liquid-crystalline polyester (C) with respect to 100 parts by mass in total of the polyamide (A), the liquid-crystalline polyester (B), and the non-liquid-crystalline polyester (C) satisfy the following formulas: 60 ≤ Ma ≤ 90, 2 ≤ Mb ≤ 38, and 2 ≤ Mc ≤ Ma × 0.2-2.
本发明可提供一种聚酰胺组合物,与传统聚酰胺组合物相比,该组合物在模塑产品的耐热性和拉伸伸长率方面更为出色,在这些性能之间的平衡方面也更为出色。本发明涉及一种聚酰胺组合物,由聚酰胺(A)、液晶聚酯(B)和非液晶聚酯 (C)组成,其特征在于:聚酰胺(A)的质量分数为 Ma,液晶聚酯(B)的质量分数 为 Mb,非液晶聚酯(C)的质量分数为 Mc、和非液晶聚酯(C)的 Mc 质量份数,相对于聚酰胺(A)、液晶聚酯(B)和非液晶聚酯(C)的总质量份数 100,满足以下公式:60 ≤ Ma ≤ 90,2 ≤ Mb ≤ 38,2 ≤ Mc ≤ Ma × 0.2-2。
