The very first dry film photopolymer photoresist, DuPont™ Riston® dry film revolutionized printed circuit board fabrication methods. Today, Riston® is just as critical as ever to printed wiring and circuit-board production. Fabricators choose DuPont for improved product and process solutions that keep them both competitive and profitable.
DuPont™ Tefzel® ETFE fluoropolymer resin is a modified ethylene-tetrafluoroethylene fluoropolymer available as pellets, or as powder for rotational molding. Tefzel® ETFE resin combines mechanical toughness with an outstanding chemical inertness that approaches that of DuPont™ Teflon® fluoropolymer resins.
Zytel® nylon resin is the most versatile of plastics - easy to process, easy to modify, and environmentally responsible in production and in reuse. It's tough, light and surprisingly resilient in hot, chemically aggressive and humid environments. DuPont™ Zytel® HTN high-performance polyamide bridges the performance gap between conventional engineering resins and high-end specialty polymers.
