Non Asbestos Fiber Sheet

Compressed Non-Asbestos fiber jointing sheet

Most of today's Compressed Non-Asbestos gasket materials contain either Kevlar, an aramid fiber, fiberglass, carbon fiber, graphite or another mineral fiber.
Regardless of the manufacturer, the basics are the filler and the elastomer used. The basic Elastomers are: NBR (Buna-N), SBR, EPDM or Neoprene. If you examine which material you need (as defined by the application) and select the non-asbestos gasket material with that elastomer you will usually do well. This method will also allow you to select a competitive brand that will serve your application. No two materials are identical so caution must always be exercised. In general, the common "Binders" are:
NBR - good for oils, gas, mild chemicals and water
SBR - good for saturated Steam, mild chemicals inert gas and water
Neoprene - good for saturated steam, refrigerants, oils, fuels, mild acids and alkalies and water.
EPDM - good for saturated steam, mild chemicals and water
Each material listed regardless of manufacture will indicate the "Binder" which makes cross referencing equal materials a much easier task. You should however pay attention to Tensile strength (for pressure resistance) Temperature ratings, and Compression / Recovery ratings.
You must also consider for cut gaskets 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.
We at Atra Seal can assist you with a material selection of non-asbestos gasket materials or sell to you a non-asbestos gasket material on-line at ww.atraseal.com. We can also offer a number of non-asbestos gasket manufacturers products to meet your specifications.
