The multi-layer material consists of a polymer core with carbon black filler, covered on at least one face with a sequenced copolymer/ block copolymer mixture layer with a thickness such that it does not act as a screen to the static electricity dissipative properties of the core produced by the carbon black. The relative weights of the sequenced and block copolymers are in a ratio of between 1 : 4 and 4 :1, and the relative thicknesses of the core and the covering layer are in a ratio of between 5 : 1 and 20 : 1. The material can be employed in sheet form of thermo formed. |
