gasket type material overview gaskets a gasket is placed in between two objects in order to prevent leakage of any kind of the pressurized or not pressurized media. most important is the compression set of a gasket to adapt to flange irregularities and to any dimensional changes of the flange f t l e a system caused by temperature changes during operation. the k n s g gasket requires resistance against media and temperature within a e g s the range of the given application. requirements for a gasket are: • good compressibility and face adaptability • good recovery • strength bolts • limited relaxation • chemical resistance • temperature resistance bench marks for excellent gasket properties: the flange connection is the widest spread gasket application. • chemical resistance of PTFE the flange connection is a sealing system, which consists of: • temperature resistance of mica • flanges • mechanical property of steel • gasket and • compression set of soft rubber
