Wilmington, DE, March 30, 2011
DuPont Fluoropolymer Solutions announced today that a new perfluoroalkoxy-based resin for insulation of wire, cable and intricate electronic parts is now commercially available. The new fluoropolymer resin, DuPont™ Teflon® PFA 416HP, features a high melt-flow rate while maintaining very good MIT flex life. These characteristics offer coaxial wire manufacturers, semiconductor OEMs and electronic device designers the ability to coat ultra-thin gauge wire and to injection-mold fine, intricate thin-wall parts in a more efficient manner than can be done with other fluoropolymers.
DuPont™ Teflon® PFA 416HP resin provides all of the advantages of PTFE — including ultra-high thermal resistance and dielectric properties — and combines those critical attributes with a very high melt-flow rate. These inherent characteristics enable almost transparent coatings on ultra-fine wire, such as the kind used in mobile telephones, medical sensor wires, micro coaxial cables, and wireless antenna applications in headsets, laptops and smart phones. Teflon® PFA 416HP also provides excellent chemical resistance, very good stress crack resistance and easy flow for molding applications.
“Our new PFA resin is a breakthrough, high-performance product innovation that opens up even more options for fine wire applications where maximum flexibility and high thermal resistance are needed,” said Jacob Lahijani, Ph.D., senior technical consultant – DuPont Fluoropolymer Solutions. “Ultra-high thermal resistance in insulation means that highly intricate electronics can be insulated with an extremely thin, almost transparent coating and still withstand soldering. With the higher melt-flow rate, this new resin broadens the ability to injection-mold fine, intricate parts as well.”
DuPont™ Teflon® PFA 416HP is ideally suited for applications such as antennae for wireless electronics, medical probe cables, micro HDMI cables, internal wire harnesses for electronics, and other uses where high melt-flow rate, very low viscosity and high stress crack resistance are critical.
