For example, the bath sponge is made from foam!


For example, when you want to do yoga, you must use the yoga mats, yoga rollers, aerobic steps, yoga block and other many things that you can’t even think!

Foams or rubber are used in the critical industries such as oil industry, Astronomy & military industry. That means the foams or rubbers must be reliable and produced in high-end technology.


They are also great exporters and more importantly in the foam industry they are precise & creative.


Foam producers are always looking on their quality & providing the best formula to keep themselves in a breathtaking competition between other serious competitors.

You need to know that all kinds of foams are widely used in every industrial product.




In the smaller scales, the linked bubbles are called “lamellae” which is outward from the connection points.
Also, in smaller scales you can see the liquid-air interface on the surface.


If we want to speak about the structure of solid foams or solid rubbers, you must see them structure.



Foams or rubbers are both examples of dispersed media. In many ways, gas is present, so it divides into gas bubbles of different sizes (i.e., the material is polydisperse separated by liquid zones that may form films, thinner and thinner when the liquid phase drains out of the system films.

When the principal scale is small, i.e., for a very fine foam, this dispersed medium can be considered a type of colloid.

Rubber can also refer to something that is similar to rubber, such as quantum foam,polyurethane泡沫(泡沫橡胶),聚苯乙烯,XPS泡沫,酚类或许多其他泡沫或橡胶制造商是分散介质的例子。通常,存在气体,因此将其分成不同尺寸的气泡(也是材料是多分散的)。

Separated by liquid regions that may form films, thinner and thinner when the liquid phase drains out of the system films. When the principal scale is small, also for a high-quality foam, this dispersed medium can be considered a type of colloid.

Foam can also refer to something that is similar to foam, like quantum foam, polyurethane foam (foam or rubber), XPS foam, polystyrene, phenolic, or many other foam manufacturers.

The stabilization of a foam is caused by van der Waals forces between the molecules in the foam, electrical double layers created by dipolar surfactants, and the Marangoni effect, which acts as a restoring force to the lamellae.

Many things effect on foam stability. More importantly, we need to select the right surfactants. As mentioned earlier, surfactants are needed to foam bubbles and make the generated foam or rubbers more and more stable.


Surfactants that are good at foaming may not be good at reducing IFT.

One of the most important aspects of foam fracturing is to keep the foam in motion. If the foam is not in motion, it will be unstable. When rubber’s moving has stopped, gravity will cause the free fluid in the foam to drain. This drainage can cause foam more instable.

Now we want to speak about Marangoni effect.

This effect depends on the liquid that is foaming being dirty. Generally, surfactants in the solution decrease the surface tension.

The surfactants also numerous together on the surface and form a layer.

So, the surfactants are less concentrated in the indentation.

Also, surface stretching makes the surface tension of the indented spot greater than the surrounding area. Consequentially, since diffusion time for the surfactants is large.


Being a multiscale system involving many phenomena, and a versatile medium, foam can be studied using many different methods. According to the different sizes & scales, experimental methods are diffraction ones, mainly light scattering methods at sub-micrometer sizes & scales.


The organization between bubbles has been studied numerically using sequential attempts of evolution of the minimum surface energy either at random (Pott’s model) or you can choose the determination (surface evolver).

The evolution with time can be simulated using these models, or the bubble model (Durian), which according to the motion of every bubbles. You need to know that these specs can be tested again. You also can tell us your experience.

Observations in the structure can be made by shining the foam with laser light or x-ray beams and measuring the reflectivity between bubbles. Observations of the interlocking structure can be done with scattering among the neutron.

A typical light distributing (or diffusion) optical methods, multiple light scattering coupled with vertical scanning, is the most widely used technique to monitor the dispersion state of a product, hence identifying and quantifying destabilization phenomena. It works on any concentrated dispersions without dilution, containing rubbers. When light is sent between the sample, it is distributed by the bubbles.

The distribution intensity is directly proportional to the size and volume fraction of the dispersed phase. Therefore, local changes in concentration and global changes in size (ripening, coalescence) are monitored.

Foams applications


For example, fire extinguishers are using the liquid foam to extinguish the fire.

The liquid foams having the very unique structure that you can see high specific surface area is exploited in the chemical procedure.

第二个类橡胶是固体橡胶or solid foams. They are lightweight with engineering cellular material. You need know that foams are mostly classified into the two kinds in their category.



The closed cells are usually having better moisture absorption, higher dimensional stability & higher strength compared to closed cell foams or rubbers.


Foam, in this case meaning “bubbly liquid”, is also produced as an often-unwanted by-product in the manufacture of various substances.

For example, foam is a serious problem in the chemical industry, especially for biochemical processes.

Many biological substances, for example proteins, easily create foam on agitation or aeration. Foam is a problem because it alters the liquid flow and blocks oxygen transfer from air (thereby preventing microbial respiration in aerobic fermentation processes).

For this reason, anti-foaming agents, like silicone oils, are added to prevent these problems. Chemical methods of foam control are not always desired with respect to the problems (i.e., contamination, reduction of mass transfer) they may cause especially in food and pharmaceutical industries, where the product quality is of great importance.

Mechanical methods to prevent foam formation are more common than chemical ones.

What is foam faq

  • 1.What is foam material

    Foam or rubber (also known as cellular, sponge, or expanded rubber) refers to rubber that has been manufactured with a foaming agent to create an air-filled matrix structure. Commercial foam rubbers are generally made of either polyurethane or natural latex.

  • 2.What is foam in chemistry?

    Summary. A foam is a dispersion of a gas in a liquid prepared using a foaming agent, which in most cases consists of one or more surfactants. Foams can be prepared from two overall processes termed condensation and dispersion. This chapter discusses some applications of foam structures.
