Heat Exchanger Gasket Types
Plate heat exchangers are an important part of heat exchange technology in process industry equipment. The elastic gasket that seals between the plate are consumable part and is also an easily aging part under natural conditions. Its service life has an important influence on the service life of the plate heat exchanger. If these gaskets heat harden and lose their original elasticity, the heat exchanger will not work properly.
FPM has outstanding heat resistance (200 ~ 250 ° C), oil resistance, can be used to manufacture cylinder liner seals, plastic bowls , rotating lip seals and heat exchanger gaskets, which can significantly improve the use time.
The main chain of EPDM rubber is a fully saturated linear structure containing no double bonds, and its side chain has a diene ruthenium, which can be vulcanized by sulfur. EPDM rubber has excellent aging resistance, ozone resistance, weather resistance, heat resistance (long-term use in 120 ° C environment), chemical resistance (such as alcohol, acid, alkali, oxidant), but not Resistant to aliphatic and aromatic solvents
