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.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
