Any suggestions about a material that has more expanding properties when exposed to moisture than Super Absorbant Polymers? Or binary materials...IE...when mixed together and then moistened have a greater expansion capability than SAP's?

If moisture is not main consideration then there are certainly chemical combinations which will produce soft or structural foam when mixed . Enormous expansions from small quantities of chemicals are possible .
Thank you for your reply. Will want moisture, in the environment where it's being used, to create the expansion. Looking for other things similar to SAP's that may have even more expansion capability or other characteristics. Also, I haven't ruled out using other non-caustic chemicals that would work in a binary fashion and "enormously" expand when mixed together. Any specific suggestions?
