Claims15
A molded article comprising a composition comprising:
- 25 to 77 weight percent of a polyamide;
- 20 to 45 weight percent of a polyphenylene ether;
- 3 to 30 weight percent of a polyetherester amide;
- wherein weight percent of each component is based on the total weight of the composition;
- wherein the molded article is an automotive component;
- and
- wherein the molded article exhibits:
- a heat deflection temperature of 120° C. or more, determined according to ASTM D648;
- a surface resistivity of 108 ohm/sq to 1013 ohm/sq, determined according to ASTM D257;
- a dielectric constant less than 4, determined using QWED split post dielectric resonator and Agilent PNA network analyzer;
- a flexural modulus of 1200 MPa or more, determined according to ASTM D790;
- and
- a parasitic capacitance of less than or equal to 0.2 pF, determined using a capacitor signal detector at 100 kHz and 1 volt.
