DuPont and cable industry collaboration yields safer, more durable cables with Vamac® halogen-free flame resistant compounds

03.07.2012
Flame-retardant cables and hoses for the highly regulated railway, marine, military and automotive industries have reached new levels of safety, durability and ease of installation with insulation and jacketing compounds based on DuPont™ Vamac® ethylene acrylic elastomer (AEM).

Close collaboration between DuPont and wire and cable makers to develop optimum formulations using Vamac® has resulted in a unique combination of properties that outperform other commonly used polymers for flame-retardant cables and hoses, such as ethylene vinyl acetate (EVM). Optimized Vamac® compounds combine enhanced fire and oil resistance with better low temperature flexibility (without plasticizer), and superior heat resistance up to 175°C.

Cables with jacketing of halogen-free flame-retardant (HFFR) compounds based on DuPont™ Vamac® DP ethylene acrylic elastomer (AEM) provide new levels of safety, durability and ease of installation in confined spaces for highly regulated railway, automotive, marine, and military applications.

These collaborative programmes have yielded innovative jacketing and insulation solutions to fulfil the most stringent industrial requirements in, for example, the automotive and railway industries:

- For the automotive industry, Vamac® G is the preferred solution for applications such as transmission wire jacketing, protective ignition wire sleeving and battery cables.
- For the railway industry, where high flame retardance, low smoke and low toxicity are critical, Vamac® DP is the solution of choice for power and communication cables. In addition, the DuPont AEM accepts the high levels of metal oxide fillers required in high-performance low fire hazard compounds for rail transportation, as well those for military, marine and oil and gas applications.

“In very challenging cable environments where any compromise on performance is unacceptable, our cable industry customers choose DuPont™ Vamac® AEM as the base elastomer for their HFFR jacketing compounds to ensure extra durability and fire-resistance,” said Anne-Laure Brison, Wire & Cable EMEA Market Segment Leader, DuPont Performance Polymers.

“Extra durability is the result of its unique combination of superior fluid resistance, flexibility at low temperature without plasticizer, and long-term heat resistance. Since Vamac® has a high acceptance of flame retardant fillers, it enables the design of low fire hazard compounds for specialty cables. In total, Vamac® offers a very flexible solution for tough cable environments,” she added.
Different examples of high performance, lower fire hazards cable sheathing and insulation using Vamac® have been shown on the DuPont stand at DKT 2012.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
