Material selection for sealing component
Im exploring the possibility of using an elastomeric foam for a sealing component.
The seal is for use in a cannula or tube, to form a pressure barrier between spaces,
and adapted to accommodate instrument diameters ranging from 5 to 12 mm passed through.
Essentially a plug with a small central orifice, slightly smaller than 5 mm.
The foam should compress and displace according to the diameter of the instrument placed through.
Any suggestions or recommendations for such material are greatly appreciated.
Are you still working on this?
What differential pressure must you seal?
What is driving you to a foam instead of a typical rubber seal?
