It is easily regenerated because it has high permeability and solidity. In addition, filters made of stainless steel fiber are also used in polymer products such as plastics and food production, metallurgy and chemical production. It is widely used to filter high temperature liquids where high pressures are required. In addition, its robustness and regenerative properties are also used in the refining of milk, juices and edible oils.
