CLASS E SEGMENT CABLES AND TUBES

摘要

The invention relates the use of a copolyester elastomer comprising hard blocks comprising polyester segments, polymeric soft blocks and urethane linkages, in applications with a thermal overload requirement specifying a thermal overload temperature above the melting temperature of the copolyester elastomer. The invention also relates to films as well as tubes and electrical cables, such as convoluted tubes and electrical cables for use in cable harness systems. The invention more further relates to polymeric materials with high heat properties that can be used in the tubes and cables and to tubes and cables at least comprising a layer consisting of the polymeric materials.
