The PHE gasket is an important part of the chevron plate heat exchanger. The heat gasket is affixed with the adhesive in PHE plate the sealing groove when assembling.Then ring gasket is placed in plate corner groove according to the need of fluid flow,which is allowed or prevent the fluid enter the passage between the PHE plates and to achieve the purpose of heat exchange.The blue gasket material, structure and compression ratio of the heat gasket is directly related to the sealing effect of the plate coolers. The commonly-used rubber gasket material is synthetic rubber and asbestos rubber two categories. Synthetic rubber is nitrile rubber, EPDM rubber and fluorine rubber. The physical properties of synthetic rubber gasket is permanent compression deformation and tear elongation(under the operating conditions). PHE gaskets hardness index should be based on the sealing groove form and compression.
