A covering material comprising a first layer, which forms the wearing
layer of the structure and contains an ionomer, as well as a second layer
next to the first layer. According to the invention, the first layer
contains a wear-resistant and electrically conductive ionomer
polyelectrolyte and the second layer is electrically conductive. The
first layer comprises in particularan ionomer, which is a polymer of a
co- or terpolymer of ethylene and acrylic or methacrylic acid, or any
other known ionomer, and a block polyether, the polymer being ionically
crosslinked with alkali and/or alkaline-earth and/or metal cations. The
second layer forms the bottom layer of the structure, and it is made up
of a polyolefin elastomer that has been rendered electrically conductive.
The material according to the invention is suitable as covering for ESD
applications.
