Hello,
I have 2 interesting questios, I believe, regarding polymer properties. I am designing a ball (pretty much like a basketball in size and appearance) to be used inside pressure vessels for certain corrosive fluids. The ball is inflated with air to a certain pressure in order to cushion...

I would like to know if any Thermoplastic polyurethane (TPU) is suitable for drinking water. I believe there should be many kinds of TPU, in which case it would be interesting to know if all of them don´t have problems if in contact with potable water.
Another thing would like to know if there...
I use an application in which balls made of polybutadiene are in contact with drinking water. I need to certify that the contact of the polybutadiene with the water does not affect the flavour and does not leave toxic components in it.
So, first of all I need to identify what are the elements...
The basketballs are not for playing but for engineering purposes and they need to lose as little air as possible. My concern is that the usual valves used in these balls are not that good in preventing the air leaking. Can another valve, like tire valves, be installed in a ball when it is...
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...
