Problems solved by technology

[0003] The core wires of existing high-speed transmission wires are almost all made of nitrogen foaming or chemical foaming. The insulating material is mostly polyethylene. The foaming state has a bubble-like structure, like a sponge. Although the material has a low dielectric constant, it is heat-resistant and fire-resistant. Poor performance; when the core wire is squeezed by external force, such as tape, twisted, and assembled, due to torsion, the wire will be deformed to a certain extent, and such deformation cannot be recovered; Poor melting performance; when the wire reaches a certain deformation rate, the attenuation value of the wire will be relatively poor, the characteristic impedance is unstable, and the internal delay is poor and difficult to debug; nitrogen extrusion equipment is mostly overseas technology, and its price is expensive

Abstract

The invention relates to the technical field of high speed cables, and more specifically relates to a high speed signal transmission cable insulating material with extrusion resistance and a foaming technology thereof. The high speed signal transmission cable insulating material with extrusion resistance comprises the following raw materials in parts by weight: 40-60 parts of FEP resin, 20-40 parts of EP rubbers, 5-15 parts of polyacrylate, 4-8 parts of a filler, 1-3 parts of a nucleating agent, and 10-20 parts of an anti-oxidant. The high speed signal transmission cable insulating material with extrusion resistance has the advantages of better strength, toughness as well as heatproof and fireproof performances; after the product is extruded by outside force, because the strength is high,the deformation rate is obviously small, and the product also has a certain self-repairing function.
