Abstract

In order to achieve processability in an extruder and to produce an insulation of low density and high heat resistance, the mixture preferably contains from 50 to 70 parts by weight of rigid polyethylene, from 30 to 50 parts by weight of flexible (soft) polyethylene, from 2 to 4 parts by weight of blowing agent, for example azodicarbonamide, and from 0.1 to 2 parts by weight of crosslinking agent.
