How are balloons made?

Balloons are fun, for everyone!!!!

Latex Balloons:

Most balloons that people will find in the store, used for parties, and fun activities, are made out of a liquid rubber called Latex. These latex balloons are manufactured in companies and factories all throughout the world, but can be made by following easy steps:

1) Molds of the balloon must be placed into an adhesive, which contains calcium nitrate, water and alcohol. The adhesive applies a sticky coat to the mold which allows the latex to stick to the mold.

2) It is then dipped into the compounded latex where the latex can stick to the molded adhesive.

3) >From there, the latex coated form is passed through a set of revolving brushes that makes the balloon rim at the top of the balloon.

4) The latex mold is then dipped into hot water to remove any excess nitrate, or any other bacteria's.

5) The mold is then put into an oven at 200-220 degrees Fahrenheit for 20-25 minutes.

When cured, the rubber balloon is removed from the form.

Mylar Balloons:

Mylar Balloons, or most often called helium balloons, are made for the sole purpose of withholding gasses easier and longer. Mylar balloons are made out of polyester instead of latex. The polyester withholds the helium better and for a greater amount of time.

Mylar balloons must be used when using helium instead of latex balloons. The reason for this is that Mylar balloons are able to withstand the extra pressure from the outside air because helium is less dense than air. Because the helium is less dense, it allows a balloon full of helium to float up into the air until stopped. The polyester doesn't allow the helium to get out or the air to get in as easily as latex due to the density of the particles inside polyester. Unfortunately, like most balloons, the Mylar balloon will not withstand the pressure and hold the air forever and eventually the balloon will deflate and fall to the ground.
