...e walls, air hoses, pharmaceutical stoppers, moulded articles and seals and gaskets. Ester rubbers (EVM, ACM, AEM): Ethylene-vinyl acetate copolymer (EVM, e.g.: Levapren, Lanxess) is currently a speciality rubber with preferred application in the cable (e.g. halogen-free, heat-resistant cable sheathings, title picture), flooring (flammability class B1), footwear and, in some cases, automotive sectors. In addition, manufacturers are trying to reposition EVM away from being a niche product, since...

...y sources. For instance, ethylene-vinyl acetate copolymers are being tested for production of solar cells: EVM Levamelt film could simplify fixing the silicon modules to the carrier. These copolymers, under the name Levapren, also find use in the cables, the so-called "solar leads", between the solar cell and the inverter. To advance the practicability of this application, Lanxess is currently constructing its own solar system (Fig.4). Additional new developments include, for example, an...

...y important for ensuring that wetsuits can offer optimal insulation. Highly Efficient Processes for Complex Component Production Lanxess has significantly enhanced the method used to process Levapren (ethylene vinyl acetate rubber, or EVM) by injection molding. For the first time it has succeeded in using compounds that contain a blend of two peroxides, thereby enabling vulcanization to take place in two stages. This modified processing method enables quick and easy demolding of parts (mold co...

...cks were utilized that gave the elastomers additional and in some cases very specific properties. Buna EP, an ethylene propylene diene rubber, showed excellent aging and temperature resistance. The polarity of EVA rubbers such as Levapren – made from ethylene and vinyl acetate – can be varied by adjusting the proportion of the polar monomer. In the 1970s post hydrogenation of HNBR rubber removed a pivotal starting point for aging reactions in nitrile rubbers. The result was an elastomer that had...

...ce. Like an artificial full moon they provide atmospheric lighting for every setting. For the larger Partymoon models the manufacturer uses lightweight, translucent elastomeric membranes made from the high performance synthetic rubber Levapren from Lanxess Deutschland GmbH, Leverkusen, Germany. The elastomeric material, an ethylene vinyl acetate copolymer (EVM), is weathering and UV resistant, allows light from the interior of the balloon to pass without altering its color and at the same time d...

Among the polyethylene-vinyl acetate (EVM) Levapren materials under development, a grade for impact resistance modification of polylactic acid is highly promising. The focal point of the business unit’s investment activities is Asia. For instance, a nitrile rubber plant with an annual capacity of 30,000 t was opened ...
