CABLE MATERIALS

According to DuPont, the new products offer the potential for lightweight, high-performance cabling suitable for use in high frequency signal transmission across a broad temperature range and with minimal distortion. The patented nucleants and base polymers that comprise Airquick polymer foam technology improve both the processing and end-use performance of the new Teflon® fluoropolymer foam resins in a broad range of wire and cable applications for data communications. The following grades are available:
– FFR 330: foam resins for high viscosity, high Velocity of propagation coaxial cables with heavy wall applications (1.25-5mm), for example RG11.
– FFR 550: foam resin for intermediate size coaxial cables with small uniform cell structure and good adhesion to the conductor resulting in excellent Signal Return Loss.
– FFR 750: foam resin with higher service temperature and therefore suited for rigid and semi-rigid high-frequency coaxial cables well into the GHz range.
– FFR 770: high speed foam resin for thin- and ultra–thin-walled high frequency data and micro-coax cables with the ability for self-skinning at lower void content.
“This new category of fluoropolymer foam resin will also simplify product comparisons, ease product grade selection and create a distinct technology platform for continued advancements and additions in our product portfolio,” comments Robert D Smith, Global Business Manager for melt fluoropolymers at DuPont Fluoropolymer Solutions. “Products based on Airquick technology offer exceptional value for high performance applications.”
At wire 2010 in Düsseldorf the DuPont stand illustrated the breadth of products available for the wire and cable industry from across the company’s businesses. This includes the range of DuPont flouropolymer resins used in insulated wire and cable products, marketed under the trade names of DuPont(TM) Teflon® FEP, Teflon® PFA, Teflon® PTFE, and Tefzel® ETFE fluoropolymer resins. As with the new category of fluoropolymer foam resins mentioned above, they are viewed as ideal choices for insulation and jacketing applications where low flammability, exceptional dielectric properties, high stress-crack resistance, chemical inertness, and thermal cycling capabilities are required.
Other DuPont products offered at the stand include the company’s extrudable engineering thermoplastics, from DuPont Performance Polymers, which are used for high-performance, lightweight cabling in the automotive, transportation, robotics, appliance, oil and alternative energies, to name a few. These include DuPont(TM) Zytel® nylon resins, DuPont(TM) Crastin® PBT thermoplastic polyester resins, DuPont(TM) Hytrel® thermoplastic polyester elastomer resins and DuPont(TM) ETPV engineering thermoplastic vulcanizate. The DuPont Ethylene Copolymer (ECP) business offers products such as such as Fusabond® coupling agents, Elvaloy® modifying resins, Elvaloy® AC Acrylate Copolymer resins and Elvax® Ethylene Vinyl Acetate resins. These products are particularly used in halogen-free, flame retardant (HFFR) cable compounds. Finally, DuPont(TM) Electrical Insulation Systems will be presenting its wire enamels, impregnating resins and core sheet varnishes, all marketed under the DuPont(TM) Voltatex® name, whilst DuPont(TM) Kevlar® will showcase products delivering lightweight, high-strength dielectric functionality.
DuPont Fluoropolymer Solutions is a leading producer of fluoropolymer resins, additives, films, finishes and dispersions, PTFE (polytetrafluoroethylene), PFA (perfluoroalkoxy), FEP (fluorinated ethylene propylene), ETFE (ethylene-tetrafluoroethylene) and PVF (polivinylfluoride), marketed under the registered trademarks DuPont(TM) Teflon®, DuPont(TM) Tefzel®, DuPont(TM) Tedlar® and DuPont(TM) Zonyl®. Major markets for these fluoropolymer products include the automotive, chemical processing, semiconductor, oil exploration, chemical handling, data communication, aerospace, electronics, housewares, building and renewable energy industries.
