I don't know about Silastic, but a substitute might be microporous
polypropylene fibers made by Hoechst Celanese.  I was involved in a project a
few years ago to make an aquarium for the space shuttle and we used these to
oxygenate the water.  They are sterilizable.  H-C bundles them together in
cartridges of different sizes that are ready to use. They called them Celgard
fibers, and the devices are called gas transfer devices.  the phone number for
