Typical Mechanical Properties of Flexible Ceramic Materials

The material pyrolysis yield at 1000°C is greater than 90% by weight and when retested, experiences no additional weight loss.The densified ceramic material specific gravity is 2.0 gm/cc with typically less than 0.1% porosity
100 hours boiling in Texaco Oil D955M resulted in  < 1% swelling
Steam testing of the gasket caused no problem or breakdown such as experienced with RTV rubber.
The dielectric strength of the head gasket is 500 volts/mil at 1mm thickness and with a polyimide wrapped special wire in the core of a 1MM gasket, the gasket can carry 35Kv ignition cold start (-40°F) requirements with a 200% safety margin.
