Heat exchangers gasket materials

The principal use of ethylene-propylene rubbers (ethylene-propylene-diene monomer (EPDM) or ethylene-propylene monomer (EPM) types) is in the manufacture of heat exchanger gaskets. When cured using peroxides, these materials can be used for extended periods at up to 150 °C. Normal conditions of service are high temperatures (<130 °C) and flow or static exposure to aqueous food.

A gasketed plate heat exchanger is usually significantly cheaper than a shell-and-tube heat exchanger for the same duty. This is especially the case if the shell-and-tube heat exchanger must be fabricated in more expensive materials such as stainless steel.
