Foam has many advantages.

Its greatest advantage is not only heat insulation, sound insulation and heat insulation.

Because foam does not transfer heat, it is needed in cold storage and refrigerated trucks for storing food and medicine.

Foam can insulate sound. Radio stations, theaters, telephone rooms, conference rooms and other places are needed. These places are made of foam plastic, so it is not easy for the outside sound to come in, which can keep the room quiet.

Satellite communication, atomic energy research, medicine and so on all need heat insulation materials that can withstand ultra-high temperature, and foam plastic is very suitable. In addition, people also use foamed plastics instead of cotton to make mattresses, cotton-padded clothes, gloves, hats, insoles and so on. Because it can keep warm, recently, people have also studied the use of foam plastic as a space flight suit.

Plastic is very light. For example, the cork at the mouth of a thermos bottle is very light, but the foam cork is even lighter than the cork. 10 foam plugs add up, which is similar to the weight of 1 cork. Foam is also very elastic. If a 40-ton thing is pressed on 1 m3 foam on average, its volume will be reduced by1/3; If you take off the thing that is pressed on it, it can almost return to its original appearance. Foam has so many advantages that small bubbles can play many roles. When people discovered this secret, they used the same principle and different technologies to make all kinds of foam materials. For example, foam rubber can be made by adding foaming agent to rubber. Lifeboats made of foam rubber are very light. Rubber can also be used to make furniture and other things. People also melt some metals, and then add foaming agent into them, which will produce many small bubbles in the molten metal, and then cool it immediately, and it will become a light, hard and strong foam metal. This kind of foam metal is not only light and hard, but also can be sawed, planed and drilled. It can be put on a lathe to make products of various shapes, and can also be used to make airplanes, motorboats and ships.
