Lime slurry why use EPDM rubber expansion joints?

In the process of using rubber expansion joints, generally the pipeline over lime slurry is desulfurization pipeline system, such as power plant desulfurization pipeline, or steel plant desulfurization pipeline, in the desulfurization process using the stone method, so the medium in the pipeline is stone slurry, in this case, which material rubber joint to choose for the pipeline effect is obvious? In this case, which material rubber joint can be used for a longer period of time?
EPDM rubber joints are very suitable for lime slurry pipeline, because EPDM rubber expansion joints are suitable for pipeline with acid and alkali medium and erosive force, so it is often safe to install and use in the pipeline of lime slurry. EPDM rubber is a terpolymer of ethylene, propylene and non-conjugated diolefins. The main characteristic is its superior resistance to oxidation, ozone and erosion. Because its main chain is composed of chemically stable saturated hydrocarbons and contains only unsaturated double bonds in the side chains, it has excellent aging resistance to ozone, heat and weather, and can be widely used in automotive parts, waterproof materials for construction, wire and cable sheathing, heat-resistant hoses, tapes, automotive seals and other fields.
EPDM is essentially non-polar, resistant to polar solutions and chemicals, has low water absorption, and has good insulating properties.
