Sealings/Heat Exchangers

How New Materials Ensure Reliable Sealing of Heat Exchangers

ePTFE gasket tapes for high chemical resistance—The connections to shell and tube heat exchangers pose immense challenges for the seals that are used because of both the chemically aggressive media and the frequent temperature load changes. Despite its excellent chemical resistance, polytetrafluoroethylene (PTFE) is not typically suitable as a sealing material in this case because the creep tendency of this material jeopardizes a reliable seal.
