Abstract: Thermoplastic compositions include: a polymer base resin including at least one liquid crystal polymer (LCP) resin, at least one polyphenylene ether (PPE) resin, or a combination thereof; and from at least 0.1 wt % to 10 wt % of a low-OAN carbon black. The low-OAN carbon black has an oil absorption number (OAN) of 60 cubic centimeters per 100 grams (cc/100 g) or less. The compositions have good dielectric properties.
