ASEPCO’s PTFE Diaphragms
Introducing Polytetrafluoroethylene (PTFE) diaphragms in our exceptional
Weirless Radial-Diaphragm™ Valve design!
|Polytetrafluoroethylene (PTFE) is a thermoplastic resin that is practically resistant to all fluids. Of all our diaphragm materials, it is the most chemically resistant. PTFE is non-elastic, limiting its use in certain applications. PTFE can be used with media reaching very high temperatures up to 260° Celsius. Currently, PTFE is only available for ASEPCO’s tank valves. To get specific chemical compatibility information about PTFE, we suggest that you refer to the Cole-Parmer Chemical Compatibility Database. To get more information about PTFE, look at some of the suggested resources on the Datasheet & Resources tab.||

|ASEPCO provides diaphragms created with a number of different materials. The materials vary with respect to heat-resistance, chemical-resistance, and durability. The table below shows basic compatibility information.||Please do not use this information as your sole method for determining whether an elastomer is right for your specific process. Before using any elastomer in a process you should verify its compatibility with an elastomer expert.|
