    • The invention relates to a plastic component for use in a lighting system, the plastic component comprising a semi-aromatic polyamide (X) comprising repeat units derived from aliphatic diamines and dicarboxylic acids wherein: (a) the aliphatic diamines consist a mixture of 10-70 mole % of a short chain aliphatic diamine with 2-5 C atoms and 30-90 mole % of a long chain aliphatic diamine with at least 6 C atoms; (b) the dicarboxylic acids consist of a mixture of 5-65 mole % aliphatic dicarboxylic acid and optionally aromatic dicarboxylic acid other than terephthalic acid, and 35-95 mole % terephthalic acid; and (c) the combined molar amount of terephthalic acid and the long chain aliphatic diamine is at least 60 mole %, relative to the total molar amount of the dicarboxylic acids and diamines. The invention also relates to a polymer composition that can be used for making the said plastic component comprising 100 pbw of a semi-aromatic polyamide (X) and 1-250 pbw of an inorganic material.
    • 本发明涉及一种用于照明系统的塑料部件,该塑料部件包括半芳族聚酰胺(X),其包含衍生自脂族二胺和二羧酸的重复单元,其中:(a)脂族二胺由10- 70摩尔%的具有2-5个C原子的短链脂族二胺和30-90摩尔%具有至少6个C原子的长链脂族二胺; (b)二羧酸由5-65摩尔%脂族二羧酸和除对苯二甲酸之外的任选的芳族二羧酸和35-95摩尔%对苯二甲酸的混合物组成; 和(c)相对于二羧酸和二胺的总摩尔量,对苯二甲酸和长链脂族二胺的组合摩尔量为至少60摩尔%。 本发明还涉及可用于制造所述塑料组分的聚合物组合物,其包含100pbw的半芳族聚酰胺(X)和1-250pbw的无机材料。
