Or does helium perish the rubber.

As the outside pressure(atmospheric pressure) always decreases with height,any balloon filled with a lighter gas like Heliem or Hydrogen will be going on expanding as it rises up.As there is a limit for this expansion,it will definitely burst at a particular height.The bursting height may differ depending upon the thickness of the balloon and the amount of gas given.The weather balloons that are released to get weather data from the upper levels sometimes grows ten times bigger before it bursts.

At about 45Km atmospheric pressure is about 1/100 of sea-level, but temp decrease is only about 50K
So Vol at this height using simple PV/T=constant would give a Vol increase by a factor of 100*250/300 approx= about 80 times.. about 4 and 1/3 times its diameter.So balloon would probably burst!

at high altitudes, the place is freezing way below -100 degrees celsius, they dont get up to tht high level, the pressure will crunch up the helium molecules and the balloon floats back down because of gravity

The heluim will leach through the rubber eventually.
