This material is used widely for gaskets in Power Transformer and Heavy Engineering applications. As an oil resistant gasket material with superb sealing properties it is also used across many automotive and industrial applications. It has greater stability than rubbers and higher conformity to non-asbestos materials and is often the preferred solution to applications where other materials often fail.
