Vamac® Ultra HT achieves continuous heat resistance up to 180°C, with peaks to 200 °C, which, coupled with improved mechanical properties, identify it as an ideal candidate for demanding automotive applications such as turbo hoses and air ducts.
DuPont™ Vamac® Ultra HT ethylene acrylic elastomer (AEM) offers continuous heat resistance up to 180°C, with peaks to 200°C, higher flex fatigue resistance and enhanced mechanical properties, better low temperature flexibility and superior acid resistance in blow-by gas and exhaust gas recirculation environments than standard AEM, making it an ideal candidate for automotive turbo hoses and air ducts.
“Vamac® Ultra HT is designed to answer the need for high performance hoses in modern automotive engines, and especially to meet the demand for higher temperature resistant turbocharger hoses and ducts. Its dynamic performance and superior thermal resistance mark a further step in the development of the Vamac® product range, while processors will continue to benefit from an accommodating polymer for their formulations,” said Patrick Cazuc, Automotive Director Europe, DuPont Performance Polymers.The latest manufacturing technology for Vamac® enables the polymerization of AEM grades with optimized structure and chemical composition, resulting in significant improvements over existing standard Vamac® elastomers.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
