Balloon envelope material

  1. Oct 5, 2012 #1
    Hello all!

    I am looking to begin working on some balloon testing. I have a general idea of how I'm going to perform this. For the balloon envelope, I wish to use ripstop nylon, but I have no clue what would be the best way to make it gas-proof? I have considered coating it with both liquid latex and polyurethane, but I don't want to make a mistake.

    Do any of you have a suggestion how to do this?

    Thank you, GTeclips

    Latex is known to leak a lot, don't use it.

    PU is at least mechanically strong.
