Improved electrical and mechanical performance for insulating intricate electronics

11.05.2011
New PFA-based resin provides advanced performance for electronics and cabling applications

DuPont Fluoropolymer Solutions has announced the commercial availability of a new perfluoroalkoxy-based resin for insulation of wire, cable and intricate electronic parts. The new fluoropolymer resin, DuPont™ Teflon® PFA 416HP, features a high melt-flow rate while maintaining very good MIT flex life.

Whereas standard PFAs with a melt flow rate (MFR) of 40 g/10 min would be situated on the blue or red line, DuPont™ Teflon® PFA 416 HP has been specifically designed to provide a higher MIT flexlife (approximately 4000 cycles to failure) at such elevated rates of flow.

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.To obtain product information and learn more about applications for PFA resins, visit www.dupont.com/416HP.
