DuPont’s Zytel HTN selected for use in USB Type-C 3.1 connectors

DuPont’s Zytel HTN high-performance polyamide resin has been selected for use in reversible-plug USB Type-C connectors, which are forecast to replace Type-A and Type-B connectors and rule as the universal port for all devices, including desktops, laptops and mobile phones.

Requirements for use in USB Type-C and Type-C 3.1 connectors proved to be challenging for existing engineering plastics. Wall thickness in Type-C connectors can be as little as 0.18mm – less than 2 stacked sheets of paper.

Zytel HTN FR52 non-halogen products also offer processing advantages compared with other PPA resins. Zytel HTNFR52 NH products can handle the processing requirements of overmolding metal that is needed to manufacture these connectors and exhibits lower moisture absorption than other high performance polyamides.

With the very high flow performance, Zytel HTN FR52 non-halogen products allow customers to inject the materials at lower temperatures, which creates less mold deposit. This combination of features helps improve the productivity by reducing cycle time, increasing uptime and minimizing maintenance costs.

Zytel HTN FR52 non-halogen materials are already being commercially employed by several ODMs (original design manufacturers) serving global OEMs.
