Comprehensive Product Range
Elka Elastic comes in all grain sizes of the FEPA (European Federation of the Producers of Abrasives) standard, from 16 to 1000 in the following qualities
l 10 C green silicon carbide
l 10 A brown aluminium oxide
l 30 A high purity white aluminium oxide
The hardness of Elka Elastic products ranges from 30 Shore A to 80 Shore D.
The maximum permissible speed lies between 10m/sec and 50m/sec, depending on the hardness of the Elka Elastic wheel.
Our comprehensive product range can thus handle almost all grinding and polishing tasks – we meet special requirements with customised solutions.
