The polystyrene structure is composed of hydrogen and carbon and is a long hydrocarbon chain. This chain has substituents that are attached to phenyl ions. In general, polystyrene structure consists of the formula n(C8H8).

This chemical contains hydrogen and carbons that are regularly bonded together. These atoms are bonded by a Wonder Waltz bond. This polymer has thousands of atoms that are next to each other and there is a lot of intermolecular force between the atoms that make it up. In this article from Petroproviders, join us to introduce you to polystyrene structure.

Discovery of polystyrene structure for the first time in the world

In 1839, Barry first identified Edward Simon with a polystyrene structure. He was able to introduce this substance to the world, but he did not know what a valuable discovery he had made! Subsequently, in 1934, polystyrene was used commercially as a monomer and polymer.

In the same year, Dow was able to extract styrene from petroleum products. This great discovery led the company to market polystyrene commercially. This valuable material became very popular in World War II and it was discovered that polystyrene could be an electrical insulator. This made this material more widely used. Subsequently, this material was recognized as a soft plastic with impact and heat resistance.

If polystyrene is exposed to heat, its intermolecular bonds are weakened. This softens the polystyrene and turns it into different shapes. As mentioned, the polystyrene structure is composed of hydrogen and carbon. For this reason, this material has good impact resistance.

In 1950, various operations were carried out to produce different polystyrene materials. In these experiments, different methods were discovered to produce different grades of PS. In these methods, the styrene monomer is heated and enters the molding machine. After that, the molding method is done on it. Then different grades of polystyrene are made. In the continuation of this article, we will show you the types of polystyrene grades.

Polystyrene structure in a variety of grades

Polystyrenes are produced in 4 different grades: GPPS polystyrene, HIPS polystyrene, EPS polystyrene, and XPS polystyrene. These 4 grades are made according to different molding methods. These grades have special features and their applications are diverse. The polystyrene ingredients in these 4 grades are usually the same; The reason for the difference between these grades is in the way they are molded.

General Purpose polystyrene and its ingredients

In general, one of the simplest polystyrenes is GPPS. This polystyrene, which has very good transparency, has little impact resistance. It is an electrical insulator and is known in commercial markets as “crystal”.

GPPS polystyrene is made up of hydrogen and carbon, which are held together in very long chains.

High Impact polystyrene and its components

This polystyrene, which is slightly more resistant than GPPS, is translucent. This substance is easily recycled in nature and is not harmful to human health and the environment. In addition, HIPS is used to make various products; For example: making plastic containers, making building insulation, making car parts, and making medical supplies.

Expanded polystyrene

This polystyrene is a very popular grade among polystyrenes. This PS has foam properties and can have a large volume. It is lightweight and is known in commercial markets as “Ionolite”. This polymer is used in various construction industries and can be used to produce building insulation.

Extruded polystyrene or XPS

This grade of polystyrene is another type of polystyrene. This PS has special features that make it have a variety of applications. polystyrene structure in XPS grade is the same as carbon and hydrogen, But the molding method of this polymer is different from other grades of polystyrene. For XPS molding, it is injected into the mold. The plastic then dries and transforms into the desired shape.

Applications of polystyrene

PS products

PS products

This material is used to make various plastics. One of the most important applications of PS is its use in construction. This material has a large volume and is lightweight; For this reason, it reduces the dead load of the building by about 15%. In addition, it will reduce construction costs and reduce the consumption of cement and concrete. Other applications of polystyrene:

  • Use of PS in the manufacture of thermal insulation
  • Use polystyrene to make foam blocks on the roof and floor of buildings
  • Use this polymer for food packaging
  • Use of polystyrene to make medical and cosmetic devices
  • Use of polystyrene to produce thermostatic plastics
  • Use PS to build earthquake-resistant buildings

Summary of polystyrene structure review

In this article from PetroProviders, we saw the polystyrene structure together. This polymer is made of a long hydrocarbon chain. Different grades of polystyrene are made of the same two atoms. The only difference between PS grades is in the way they are molded and produced.

Polystyrene is used in various industries. These materials can be easily recycled and are not harmful to human health. You can share this article with your friends; If it was useful to you! If you have questions about polystyrene structure, you can ask our experts in the comments section.
