    IPC: C08L27/18

    Abstract: A polymer alloy composition including: (a) a fluoropolymer selected from fluorinated ethylene propylene (FEP), perfluoroalkoxy alkane (PFA), ethylene tetra-fluoroethylene (ETFE), and a terpolymer of ethylene, tetrafluoroethylene, and hexafluoropropylene (EFEP); (b) a compatibilizing agent; and (c) a polyether imide (PEI) or polyimide (PI). Also disclosed is a method of forming a thermoplastic alloy. The polymer alloy may be used to form various extruded workpieces including, for example, a bag, film, container, filament, food package, coating (such as a coating or jacketing for a wire), powder for powder electrostatic powder coating, powder for dispersions, compression molded and various injection molded parts.

    Abstract: A system and method for manufacturing wire and cable products with a polymer cable component is provided. The systems and methods include increasing the hardness of a polymer cable component in order to reduce compression and deformation of the cable components during manufacturing. In some instances, the hardness is temporarily increased prior to or during the process of creating twisted pair or during the cabling process.

    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.
