Thermoplastic Polyurethane (TPU) Film
- Does anyone know where I can get a small amount of Thermoplastic Polyurethane (TPU) film to build my own bladder? I'm looking for maybe 50 square feet. I live in the United States, so I wasn't sure if having it shipped from out of state would cost a lot more. I haven't had any luck finding any film that ships from the U.S.
- Thanks Joe,
I'm tempted to buy some too.
My pvc trampoline repairs abilities are poor.
Making a torus ring shape could be tricky but maybe possible for a home hobbyist type.

Gas and treatments for filling bladders
Air is the most common filling gas for kite bladders. But what are other choices? And what additives might be helpful? Metering and monitoring fill gases and additives?
Many systems have no pressure-keeping system besides direct pumping by a person. Bladders that are kept in changing weather, changing altitudes, changing temperatures invite aloft pressure-keeping devices that will release pressure and add pressure as needed. PKS
