thermal insulation gasket
Ceramic Fiber Gasket is appropriate when an inexpensive heat seal is required. Only used where sealing pressures are low, it happily operates in areas where temperatures are in excess of 800C. It is soft and can be easily laminated to form thicker seals, hence flange finish is not particularly important when using this material. Used mainly as high temperature insulation for sensitive apparatus it has good dielectric strength and so it is often used as an electrical insulation. Usually supplied with an organic binder to improve it's tensile strength.
