CNAF GASKETS (NON-ASBESTOS FIBRE)
Mostly Non-Asbestos Gasket materials contain either Kevlar, Aramid Fiber, Fiberglass, carbon, graphite or another mineral fiber. Can be manufactured any shape.
We should pay attention to Tensile strength (for pressure resistance) Temperature ratings, and Compression / Recovery ratings. You must also consider Size, Temperature, Application, Media, Pressure, Speed (if dynamic) of your specific application. If this is for a finished gasket you will also want to consider bolt loads, the size of bolts, the number of bolts, the bolt material and the available torque.
