Levapren®

Levapren® (EVM) is a specialty rubber, that can cope with the growing demands of the cable and construction industry as well as the automotive industry.

Levapren® is a highly sophisticated material from LANXESS which offers an impressive range of exciting characteristics. Due to its outstanding compatibility with a number of fillers and polymers and its low viscosity, Levapren® is an ideal solution for a variety of formulation issues encountered when using conventional rubber substances. This rubber can also help to significantly improve the property profile of other polymers.

THE NOMENCLATURE OF LEVAPREN

Levapren® is formed by copolymerization of ethylene and vinyl acetate. In principle Levapren consists of methylene units forming a saturated polymer backbone with pendant acetate groups. These rubber-like polymers are designated "EVM"(1) according to ISO 1629: 1995 (E) nomenclature. The presence of a fully saturated main chain is an indication that Levapren® is a particularly stable polymer. Degradation generally only occurs at very high temperatures and even then very slowly.

 

(1)In accordance with ISO 1043-1: 1987, the abbreviation E/VAC is to be used thermoplastics. The abbreviation EVA is also frequently used.
