Prosthetic foot design uses Hytrel®
The Niagara Foot™ is an affordable, high-performance prosthetic foot initially designed and intended for active individuals who have been victims of landmines. Its novel, energy-return design relies on the stiff yet, flexible properties of Hytrel® to provide user benefits in terms of stability, effectiveness and comfort.
Rail Pads Made for Heavy Loads With DuPont™ Hytrel®
Pandrol, a leading provider of engineered rail and fastening systems, worked with DuPont to design more durable rail pads, after heavily loaded coal trains displaced rails and roadbeds on a vital route. The new system resulted in no track failures in over ten years of service.
Concept for e-Mobility Seating
It is believed that the interior design of the automotive will rival exterior design in importance. The seating and interiors will become the differentiator that powertrain once was for OEMs. This new concept for e-Mobility seating suggests Office style thin suspension seating made with Hytrel® can replace PU foam and metal springs.
Hot Runner Manual for Robust Molding of Semi-crystalline Resins
Maximizing productivity is an important factor in determining part cost. One way to improve productivity is using a hot runner system. The decision when to use a hot runner system is mainly influenced by “yield” as hot runners can add complexity and cost to molds and require additional maintenance. Due to continuous improvement in the hot runner design a robust molding process is possible even with traditionally more thermally sensitive thermoplastic resins.
Press Blow Molded CVJ Boots
DuPont collaborated with Ossberger to accelerate the development and launch of new Hytrel® grades for inboard and outboard CVJ boots. Also, to develop silent outboard CVJ boots especially for hybrid and full-electric vehicles.
