Abstract
A polypropylene composition for use in high-frequency radio-wave applications of 6 GHz or greater comprises a mixture of a polypropylene and hollow glass bubbles having an average diameter or particle size of from 5 μm to 80 μm. The polypropylene composition further includes at least one of glass fibers having a length of from 0.5 mm to 10 mm and a width or diameter of from 5 μm to 15 μm, aluminum oxide fibers having a length of from 1 mm to 5 mm and a width or diameter of from 1 μm to 30 μm, a cyclic olefin copolymer, and a polycarbonate. The polypropylene composition is prepared by modifying a polypropylene by melt blending the polypropylene with the various materials.
