A communications cable is provided that includes a pair of twisted pair of wires, each coated with a fluoropolymer insulator. The twisted pair of wires is configured to carry a differential signal, such as a differential data signal and/or a differential power signal. The fluoropolymers are highly effective insulators and significantly reduce both the effects of internal and external electromagnetic interference while maintaining low cable attenuation, even when operating within a temperature range of −40° C. to 150° C.

A resin composition contains propylene, ethylene, and styrene, and has a melting point of 140° C. or more and 150° C. or less, and the enthalpy of fusion of the resin composition is 55 J/g or more and 90 J/g or less.

The present disclosure relates to a UV- and heat-curable ladder-like polysilsesquioxane copolymer and a method for preparing the same. Since a controlled functionality can be provided only on a desired region via a thiol-ene click reaction without an additional additive, an insulating layer having a low dielectric constant and a microcircuit pattern can be formed without an additional etching process.

A communication cable includes two-core communication wires, a drain wire, and a metal foil collectively covering the two-core communication wires and the drain wire.
