TEFLON encapsulation is the primary source of the chemical
compatibility of these O-rings. In general, TEFLON resins
are compatible with a broad range of chemical environments,
including those in the following chart. |
|
|
|
|
Molten alkali metals, fluorine
and several complex halogen compounds
are incompatible with TEFLON resins and should be
avoided.
