COAXIAL HIGH-FREQUENCY CABLE AND DIELECTRIC MATERIAL THEREOF

摘要

The invention relates to a coaxial high-frequency cable comprising an inner conductor (1), a dielectric material (3) formed about said inner conductor (1), and an outer conductor (4) formed about said dielectric material (3). According to the invention, said dielectric material (3) is made from an expanded polymer blend compounded from two .alpha.-olefi n polymers of different densities, whereby the polymer of the higher density forms the matrix of the polymer blend.
