Hello,
I use special balls (thicker than a regular basketball but with the same characteristics) for hydraulic engineering purposes. These balls must sometimes be inflated at high pressures (more than 70 psi) and then be put inside a pressure vessel connected to a pump line which will contain water under high pressures (200 psi or more). Sometimes this water pressure will vary (hydraulic oscilations or transients) making these balls expand and contract following these variations (the air inside the balls will act as a buffer against high and negative pressures in the water, threfore protecting the pipe).
The question finally is: Can somebody recommend me a special polymer that can be used as a coating surrounding the polybutadiene of the ball to prevent the air to leak through the material? Or maybe manufacture the ball entirely on this polymer.
