Non-woven abrasives are a three-dimensional network of flexible nylon fibres with resin globules, saturated with abrasive grains. This ‘open weave’ construction provides a continuous supply of new grains when the fibre and old grains wear out.

SiC (Silicon Carbide) is the hardest and sharpest of the minerals used in abrasives. Its hardness and very sharp form, make this abrasive ideal for various applications that do not require great pressure when cutting. Its grains are friable and, when broken, they continually expose new cutting edges that allow rapid removal of the material. It is more aggressive than Alox but wears out more quickly.

The indicated grits are the most common for the operations in question, but they do not exhaust all available alternatives. We will be happy to help you find the best solution for your case.

The indicated dimensions are merely illustrative and are common in the industry. OTA does not list them, as it uses an MTO system tailored to the needs of each client.

OTA manufactures practically all types of joints, whatever the material. Although there are base references, OTA’s MTO model involves adapting the type of joint to each specific need.
