Metal corrosion phenomenon of electro-chemical degradation is typical of metals which leads to the loss and detachment of material beginning with the surface, and above all to the loss of mechanical properties.
In particular severe operating environments, where the material comes in contact with certain chemicals and water, metal surface treatments are critical to shielding the surface from corrosive phenomena.
Unlike metals, polymers are not affected by corrosion and are often used as metal coatings to create protective barriers.
More specifically, PEEK, with its unsurpassable chemical resistance to aggressive acids, can replace metal alloys, even in the severest environments, allowing for maintenance cost reduction due to such metal corrosion phenomena.
The incredible characteristics of corrosion resistant polymers are widely used in the following sectors:
- Chemical industry
- Oil & Gas
