Sichem using the Dupont HS10 process. FMI (recently renamed Sichem) sheet gasket materials are designed for a wide range of demanding industrial requirements including gasket and bearing applications.  Sichem is filled PTFE, uniquely combining the properties of PTFE with other materials.  Those materials enhance the physical properties of PTFE and results in a sheet gasket material with near uniform tensile strength. Many competing materials are skived causing a week tensile strength direction in a sheet gasket material. Sichem shows less cold flow and greater sealing ability than other filled PTFE  materials or Fluorocarbons.  It maintains the chemical attack resistance and the temperature range of PTFE.

Using a generic gasket materials can make sense, but it can also get you into trouble and cost you many times over the 2 cents you saved. There are a lot of cheap imports causing down time. It is always wiser to buy a branded product, or genuine Grafoil, Teflon, Viton, Kalrez or other certified product (which don’t come branded). There is a place and time for generics, and we do offer them, just be careful and buy them from a reputable source like American Seal & Packing (and our associated companies like We have helped many customers overcome failed gasket applications.
