Abstract: 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.

Abstract: Provided is a tetrafluoroethylene/hexafluoropropylene copolymer which is less likely to form a lump, or is less likely to form a large lump even if a lump is formed, during the formation of an electric wire. The tetrafluoroethylene/hexafluoropropylene copolymer has a melt flow rate measured at 372° C. of 35.0 to 45.0 g/10 minutes and a swell of −8.0% to 5.0%, the sum of the numbers of —CF2H groups and unstable end groups being 120 or less per 1×106 carbon atoms.

Abstract: Adding silica particles having specified collective characteristics to a fluororubber formulation enhances direct adhesion between the fluororubber formulation and a copolymer upon curing. Specifically, as measured before being mixed into the fluororubber formulation, the silica particles have an average value of the product “(particle size)×(circularity)” that is 17.5 nm or higher and 500 μm or lower. The silica particles may also have an average particle size of between 25.0 nm inclusive and 500 μm inclusive, and an average circularity of 0.80 or higher. Alternatively, as measured after being incorporated into the fluororubber formulation and then cured, the silica particles have an apparent average value of the product “(particle size)×(circularity)” that is 32.0 nm or higher and 500 μm or lower. The silica particles may also have an apparent average particle size of between 40.0 nm inclusive and 500 μm inclusive as measured after being incorporated into the fluororubber formulation and then cured.
