Extruded polystyrene is a type of polystyrene that is stronger than HIPS. This substance has a regular and closed-cell structure. It is interesting to note that XPS is more expensive than EPS. This synthetic polymer is fragrant and is made of styrene monomer.

In addition to styrene monomer, ethylene and benzene are also present in the XPS composition. This material is usually present in a solid and foam state. This polymer is transparent and is used as building insulation. In the continuation of this PetroProviders article, join us to fully acquaint you with Extruded polystyrene.

What is the main structure of Extruded Polystyrene?

XPS Types

As mentioned, this polymer is made from a combination of styrene monomers with benzene and ethylene. The reaction of the combination of styrene, ethylene, and benzene is very interesting; That is, after combining these materials, the shape of extruded polystyrene becomes very regular and smooth. In addition, this polymer is transparent and is used for various applications in various industries.

It should be noted that this polystyrene grade has a different molding method from other grades. Due to the different XPS production methods, this polystyrene has 95 to 98% air! This makes it a great alternative to concrete and cement in construction. In addition, Extruded polystyrene is used to insulate buildings.

Naturally, this polystyrene is quite similar to EPS. The only difference between these polymers is the way they are made. To produce EPS, the polymer is dehumidified. This allows the polymer to easily gain more volume and repel moisture. But to produce extruded polystyrene, they use the injection molding method. In this method, after heating the polystyrene, it is poured into the mold. Then, using injection molding, ethylene and benzene are added to it. This makes the XPS have a regular and uniform structure.

The density of extruded polystyrene is about 28 to 45 kg per m3. This polystyrene is made of styrene monomers. Styrene monomers are also extracted from oil. So it can be said that oil is one of the most important sources for XPS production.

Various applications of extruded polystyrene in global industries

Extruded Polystyrene Uses

Extruded Polystyrene Uses

One of the most important applications of Extruded polystyrene is in the manufacture of building insulation and flooring. In addition, XPS is used to insulate the concrete floor of the building. This material is also very popular in handicrafts; Because XPS is also used to make handicrafts. This material is not resistant to water penetration! That is, water in contact with extruded polystyrene easily enters it and soaks it!

Another application of this polystyrene is to use it for thermal conductivity. This material is used as a thermal conductor due to the uniformity of the structure. This polystyrene, according to its thickness, transfers heat at different levels.

This XPS application is very interesting! The heat conductivity of extruded polystyrene is between 0.025 and 0.040 watts per meter. This application of polystyrene prevents heat loss and very good convective currents are performed in closed chambers.

For example, Extruded polystyrene is used to insulate ceilings. This prevents the substance from wasting energy. In addition, XPS ensures good heat transfer across the roof surface. So energy can be stored and transferred easily.

The lower the heat transfer coefficient of polystyrene, the greater the heat transferred. In addition, the higher the density of the material, the higher the heat transfer.

In addition, XPS is used to produce resin paints. This substance participates in various reactions and increases the quality of colors. Also, using XPS, you can increase color efficiency and color quality.

XPS is a type of polystyrene that differs in molding method from other grades of polystyrene. This makes it have a variety of features such as good heat transfer.

How is Extruded Polystyrene produced?

This material is produced like other polystyrenes. In the production process of this polymer, resin grains are used. To make XPS, it is first heated to a very high temperature to melt. Then, this material is inserted into the mold. After this step, a lot of pressure is applied to the plastic and hot plastic comes out of the molding machine. It is then cooled in the room environment and transformed into the desired shape. XPS can also be easily cut to any size.

A summary of the full XPS review

In this article from PetroProviders, we saw Extruded polystyrene and its applications. This material is a type of polystyrene that is used in various industries. In addition, XPS is used to make various materials in global industries. Extruded polystyrene has very interesting properties that make it suitable for use in construction.

In addition, XPS can be used to enhance color quality. XPS is also used to insulate buildings. It is lightweight and very impact-resistant. This material is inexpensive and easily found in global markets.
