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.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
