Can balloons be kept in high-temperature or direct sunlight environments for a long time after being inflated?

Q:Can balloons be kept in high-temperature or direct sunlight environments for a long time after being inflated?

A:No, after the balloon is fully inflated, it should be stored in a cool place as much as possible. It should not be left in a high-temperature or direct sunlight environment for a long time, as this may cause the balloon to explode. Also, when inflating, it is necessary to leave 5% to 10% elastic space and not inflate it 100%. Because high temperatures accelerate the flow speed of air molecules inside the balloon.
