The cutting fluid passes through the container filled with a load of polypropylene microfibers.
The microfibers develop a large exchange surface and posess a are able to retain a large quantity of greasy particles derivated from hydrocarbures.
The fibers are hydrophobic and collect neither water nor emulsioned cutting fluids. They can be compacted and incinerated.
There is no particular need to take care of storage, humidity or expiry date.
