A polybutylene terephthalate composition for use in high-frequency radio-wave applications of 6 GHz or greater comprises a mixture of a polybutylene terephthalate and hollow glass bubbles having an average diameter or particle size of from 5 μm to 80 μm. The polybutylene terephthalate 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 polybutylene terephthalate composition is prepared by modifying a polybutylene terephthalate by melt blending the polybutylene terephthalate with the various materials.
A polybutylene terephthalate composition for use in high-frequency radio-wave applications of 6 GHz or greater, the composition comprising a mixture of a polybutylene terephthalate, hollow glass bubbles having an average diameter of from 5 microns to 80 microns, and 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 microns to 15 microns, aluminum oxide fibers having a length of from 1 mm to 5 mm and a width or diameter of from 1 micron to 30 microns, a polyethylene terephthalate and a polycarbonate.
