Abstract

A composition consists of powdered fused silica or quartz and powdered polyethylene in a minor amount. The silica preferably consists of at least 80% by weight of particles, the largest diameter of which is between 0,15 and 0,3 millimetres and less than 10% in which the diameter of the particles is below 0,15 millimetres. The size of the polyethylene particles is less than 0,1 millimetre.
