A balloon (English: balloon) is a bag-like structure designed to be filled with gas. Balloons used as vehicles for transportation are called aerostats, while smaller balloons are often used as decorations and toys. Common balloon materials include rubber, aluminum film, latex, plastic, oxford cloth, PVC, aluminum foil, PA, and PE. The envelope of a hot air balloon is typically made of reinforced fiber or polyester.

Knowledge Popularization: What Materials Are Balloons Made Of?

There are many types of balloons available today. We’ll focus here on balloons made from natural latex, which can be used for a variety of purposes: as decorations, as arches for opening ceremonies, or customized with your own advertising designs for promotional purposes. They can also be adorned with photos of newlyweds as a heartfelt congratulation, or used to decorate dance parties and wedding floats. Nowadays, balloons have become a vibrant and eye-catching feature, steadily gaining popularity among people! In the past, balloons were known as “yang qiezi”—a playful nickname—and they came equipped with a tiny bamboo whistle at their opening. When you inflate the balloon fully and release the opening, it produces a surprisingly loud sound. Balloons can also serve as decorative items or even as means of transportation. If a balloon is large enough and the gas inside it is lighter than the same volume of air, the buoyant force generated will exceed the weight of the balloon itself along with any attached objects—such as baskets or hot-air balloons—allowing the balloon to rise into the sky.

What material are balloons made of, and do they cause environmental pollution

High-quality balloons are made from eco-friendly rubber. Once inflated and exposed to the air, the balloons begin to degrade. This can be confirmed by the oxidation that occurs on the balloon’s surface: shortly after inflation, a hazy film starts to form on the surface. High temperatures and sunlight accelerate this degradation process. After use, high-quality balloons decompose into the soil within just a few weeks, much like leaves, without causing any environmental pollution.

What gas is safe to fill balloons with

If you want a balloon to float, whether it’s an aluminum-film balloon, a latex balloon, a PVC inflatable model, or any other type of balloon, filling it with helium is the safest option. The reason balloons can float is that the density of the gas inside them is lower than that of air. Many people assume that balloons filled with hydrogen can also float—these are what we commonly call “hydrogen balloons.” Since hydrogen has a lower density than air, it can indeed make a balloon float. In middle school chemistry, we learned about the periodic table of chemical elements, which lists the elements in order of increasing atomic number: hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, argon, potassium, calcium... As you can see here, hydrogen (or hydrogen gas) has the lowest density, and helium follows closely behind. This clearly shows that helium is also a very light gas, which is why balloons filled with helium can float as well.
