thin film formation inside a rubber tube to seal air inside.
thin film formation inside a rubber tube to seal air inside.
(OP)
I am trying to find a polymer that is water soluble that we can inject into a tube. The idea we had was that a cross-linking additive could be added to form a film on the inside of the tube. The purpose of this is to stop any leaks of air in the tube. This would be analogous to "slime" that is added to car tires to seal leaks. But we don't want a liquid. We were thinking the film idea would work better for our application...It needs to be a strong flexible film for joints in the tube (rubber similar to car tire). It would be pressurized 20-100psi. We are going to try many things including poly vinyl alcohol, alginate.... Ideas on polymers and how to get them to coat a rubber and plastic surfaces and then form the film all inside the tube?
Thanks so much. Jarral

We have toyed with ideas of poly vinyl alcohol mixed with latex to make it bond with rubber and then form a film....Some research articles have studied that. Either way a fun engineering project. I am actually working with undergraduate chemistry students so it is interesting... thanks for the ideas. If we get enough one will work!
