Soft rubber linings based on bromobutyl rubber are well known in the market for their high chemical resistance and very low water absorption. This type of rubber linings are produced in an extrusion process (roller head equipment) and formulated as self-vulcanizing systems. The vulcanization takes places under ambient temperature.

They are used in flue gas desulphurization plants and also in large ore treatment plants (hydrometallurgical plants) where we find process temperatures up to 105 °C (221 F).

The paper presents two on-site application projects in the mining industry. It will be shown, what the typical demands on such corrosion protection systems are, how the application conditions are and which experiences are gained.
