With the shift to flat gaskets, gasket manufacturers have developed a myriad of products. Some of the initial materials developed proved inferior to their predecessors in regard to temperature, chemical resistance, creep resistance and sealing characteristics. Flexitallic has developed a wide range of compressed fibre gasket sheet products. Some of these products have been fibre reinforced grades, manufactured by the traditional calendering or sheeter process. Other product ranges are fibre-free and some of these materials have exceptionally good properties.
Sheet materials are used in low to medium pressure services. With careful selection these gaskets are not only suitable for general service but also for extreme chemical services and temperatures.
