Abstract
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.
