ABSTRACT:
The invention relates to the use of a fraction of hardened particles of an elastomer material of limited particle sizes between 0.1 and 1 mm, preferably between 0.3 and 0.7 mm. The order of magnitude of the admixture to every 100 parts of unhardened elastomer material lies at 5 to 60 parts, preferably 20 to 40 parts. The admixture of the particles to the elastomer material is effected before the elastomer material hardens and is done to produce a defined, non-smooth surface in end products made of elastomers.
