Tennis ball
A pressurized game ball including an air-permeable elastomeric wall defining a cavity containing a compressible inflation gas with the improvement being that the inflation gas includes predetermined mixed amounts of air and sulfur hexafluoride (SF6) gas which effectively enables the ball to retain its pressurized state within a desired range of pressures for a period of time significantly longer than the ball would remain pressurized if the inflation gas were air alone.
Their is no gas inside of a ping pong ball. It is filled with air.
Ping pong balls are made from celluloid. So the main chemicals would be nitrocellulose and camphor, though there are dyes and other ingredients varying by production company.

Yes, helium is the noble gas that is commercially used the most. It is commonly used in various industries, including cryogenics, deep-sea diving, and as a carrier gas for gas chromatography. Additionally, helium is commonly used to fill balloons for celebrations and events.
Steam? Condensation?
The balls are filled with gas and to ensure that they all have the same "bounce" they are kept in a fridge until use. Gas expands by heat.
