Because Hytrel® provides effective electrical insulation and toughness in thin layers, the replacement cables using Hytrel® are more than 40 percent smaller in diameter than the one that failed. “Smaller cable diameter means longer flex life at a given bend radius,” said Ted Beach, director of sales for Northwire. Hytrel® is ideal for cables that flex because its combination of high dielectric strength and toughness allows its use in thinner layers than many alternative materials.
Slimmer profile of cable insulated with DuPont™ Hytrel® (left) indicates longer flex life than rubber-insulated cable (right) that failed after less than two years of service on lift bridge.
The old cable, which used ethylene-propylene rubber for insulation of its 50 conductors (16 AWG), measured 1.86 inches (47 millimeters) in diameter. The diameter of the replacement cable using Hytrel® is about 40 percent smaller, just 1.1 inches (28 millimeters). Its conductors are each insulated with 0.010 inch (0.25 millimeter) of Hytrel®. Another advantage for Hytrel® is productivity and stability during extrusion of such thin insulation layers.
Northwire is also bringing the benefits of Hytrel® for insulation to manufacturers and end-users of robots, other industrial automation equipment and retractable coiled cable for various applications. The company recently obtained the first 90ºC and 105ºC UL recognitions for Hytrel® under the UL 758 standard. These are embodied in UL style 10912 AWM.Based in Osceola, Wis., Northwire specializes in custom-designed cables for industrial, medical and a variety of specialized markets.

Soft robots have a distinct advantage over their rigid forebears: they can adapt to complex environments, handle fragile objects and interact safely with humans. Made from silicone, rubber or other stretchable polymers, they are ideal for use in rehabilitation exoskeletons and robotic clothing. Soft bio-inspired robots could one day be deployed to explore remote or dangerous environments.
Most soft robots are actuated by rigid, noisy pumps that push fluids into the machines' moving parts. Because they are connected to these bulky pumps by tubes,...
Researchers at TU Graz are working together with European partners on new possibilities of measuring vehicle emissions.
Today, air pollution is one of the biggest challenges facing European cities. As part of the Horizon 2020 research project CARES (City Air Remote Emission...
Over the next three years, researchers from the Vrije Universiteit Brussel, University of Cambridge, École Supérieure de Physique et de Chimie Industrielles de la ville de Paris (ESPCI-Paris) and Empa will be working together with the Dutch Polymer manufacturer SupraPolix on the next generation of robots: (soft) robots that ‘feel pain’ and heal themselves. The partners can count on 3 million Euro in support from the European Commission.
Soon robots will not only be found in factories and laboratories, but will be assisting us in our immediate environment. They will help us in the household, to...
Scientists at the University of Leeds have created a new form of gold which is just two atoms thick - the thinnest unsupported gold ever created.
The researchers measured the thickness of the gold to be 0.47 nanometres - that is one million times thinner than a human finger nail. The material is regarded...
An international team of scientists involving the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg has unraveled the light-induced electron-localization dynamics in transition metals at the attosecond timescale. The team investigated for the first time the many-body electron dynamics in transition metals before thermalization sets in. Their work has now appeared in Nature Physics.
The researchers from ETH Zurich (Switzerland), the MPSD (Germany), the Center for Computational Sciences of University of Tsukuba (Japan) and the Center for...
