Quality	Q: How many balloons the disposable helium cylinder can fill? A: 30LB disposable helium cylinder can filling 30 balloons (9 inches), 50LB disposable helium cylinder can filling 50 balloons (9 inches).
Floating Time	Q: How long can a helium balloon float? A: Usually latex balloons floating for about 5 hours ( indoor condition data, Because the helium gas is easy to penetrate, it will slowly leak out from the gap between the rubber molecules, so the floating time depends on the quality of the balloon ).
When Inflatable	Q: When to inflate the balloon ? A: SEFIC recommend don’t charge the balloons too early in order to prevent gas leakage, half an hour ahead of the begin of activity is better. You can also add special balloon protection solution on the balloon wall to form a protective coat, which can extend the floating time, or you can use special helium balloons.
SEFIC Price	Q: Why the helium price from SEFIC is more affordable? A: From the technology, helium can be extracted from the air theoretically, but due to the content is too thin, we obtain helium from natural gas that the helium content is about 0.5% in industry. Since the helium was discovered in 1868, almost all the helium are extracted from the gas wells in the United States. Through the cooperation with the importers, SEFIC omitted a number of middlemen, customer could get the benefit directly, so you can purchase it feel free.
So light	Q: Why the cylinder I received was so light, if it haven’t filled helium or it is used? A: We fill the helium to the cylinders is according to the standard pressure, due to helium is much lighter than air, the cylinder contained helium is lighter than the one contained air theoretically, although they have same volume. You can imagine it, if we made a helium cylinder is large enough, it would fly away.
Disposable	Q: Why this helium cylinder designed as disposable? A: In consideration of helium cylinder volume, product promotion and popularization, the portability of product, and the relevant industry standards, the two type cylinders use non-refillable cylinders (just imagine, as a consumer, you only fill 50 balloons, but you need take the 10kg cylinder to everywhere, how depressed), so when you have finished filling balloons, you can treat the cylinder as garbage.
Storage Condition	Q: What is the storage condition of helium disposable helium cylinder? A: Disposable helium cylinder should be kept in cool, airy place, avoiding collision. Please tighten valves at idle state, in order to avoid leaks. There is no time limit about the storing time theoretically, Suggesting buy it in need and run out as soon as possible!
