Polystyrene raw material is composed of hydrocarbon chains. This material is produced from styrene monomer and is used to make plastic devices around the world. Styrene monomer is derived from petroleum derivatives and has long hydrogen and carbon chains with the structural formula (C8H8)n.

Polystyrenes are produced in 4 grades; GPPS grade, HIPS grade, EPS grade, and XPS grade. This material is produced in laboratories and factories and has special properties. In this PetroProviders article, join us to show you Polystyrene raw material.

Polystyrene raw material and its properties

Polystyrene raw material can be considered gas or oil. Styrene is obtained from oil and gas and, when combined with benzene and ethylene, is converted to polystyrene. Coal made from oil produces styrene.

Experiments with benzene and ethylene show that styrene monomers are well bonded. These monomers are composed of hydrogen and carbon with the structural formula C8H8. This hydrocarbon has different substitutions and has different properties.

One of the most important types of polystyrene is polystyrene foam. It is very light and has a very low density. It is a heat and sound insulator and is used to make plastic items, food packaging, air conditioners, and insulation. It is interesting to know that polystyrenes can withstand the weight of water many times their weight! This allows them to be used to build vessels.

How was the molecular chain of polystyrene identified?

In the early 1800s, scientists were working to make windshields. They wanted a material that they could easily produce and deform. This material had to be produced by simple reactions and had polymeric properties. Polystyrene was the material that scientists were looking for! It is a polymeric material and is easily produced.

In addition, natural materials such as cellulose can be used to produce it. Glucose, which is present in the cell walls of plants, is considered cellulose. Polystyrenes are also used to make silk yarns; Because the main material of silk is in their structure. In addition to polystyrene, polyethylene and polypropylene are also made from cellulose.

Bakelite, phenol, and formaldehyde are combined to form a porous resin. For the first time, in 1944, the phenolic foam was made, which was used for various applications in industry.

Use of petroleum derivatives to produce polystyrene

As mentioned, polystyrenes are derived from gas and oil. If we heat oil and gas, the styrene in it will polymerize. In addition, styrene can be polymerized by adding benzoyl peroxide. After polymerization, this material can be turned into polystyrene.

Once polystyrene begins to be produced, the test cannot be stopped naturally! Of course, inhibitors such as sulfur or oxygen, or quinol can weaken the reaction. Gradually, the reaction weakens, and the production of the polymer decreases. The polymerization reaction will then stop.

Then, by adding barium sulfate, a precipitate can be formed. Substances such as acrylic and methacrylic copolymers can also be added to the compound to add water to styrenes.

Suspensions are generally commercially available; These materials are very viscous and their use may be dangerous to human health. If we add suspensions to a composition that contains suspended solids, they can be held together. Polystyrene raw material hardens during these reactions and will have good stability.

In addition, Polystyrene raw material can be expanded by adding propane, pentane, chlorofluorocarbons, and methylene chloride.

The general design of polystyrene and Polystyrene raw material

We know that polystyrenes are made up of 8 carbon atoms and 8 hydrogen atoms! Yes! If thousands of styrene molecules are joined together, polystyrenes are made. These materials have a molecular weight of 108 and if converted to polystyrene, their molecular weight will be about 2000 or 3000 more. These molecules are easily combined and bonded together with strong bonds.

It should be noted that there may be thousands or even millions of styrenes in polystyrene. There is no limit to the number of styrenes in a polystyrene compound. Of course, it should be noted that the stability of polystyrene depends on the number of monomers; The greater the number of monomers, the greater the stability of polystyrene.

Stages of manufacturing polystyrenes in industries

As mentioned, this material is made by combining benzene and ethylene. In general, the polystyrene production reaction is simple. After the combination of ethylene and benzene, the polymerization reaction and suspension are also performed.

Polymerization is the step by which styrene monomers are converted to styrene polymers. After forming the polymer chain, the technicians stop the reaction. Then, the polystyrene beads are made and filtered to select the best polystyrene raw material.

Then, these materials are melted and enter the molding stage. At this stage, the density of polystyrenes decreases and they are suitable for the production of various plastic materials.

Summary of Polystyrene raw material review

Styrene monomer is derived from petroleum derivatives and has long hydrogen and carbon chains with the structural formula (C8H8)n. Polystyrenes are composed of monomers with 8 carbon atoms and 8 hydrogen atoms. If thousands of styrene molecules are joined together, polystyrenes are made. These materials have a molecular weight of 108 and if converted to polystyrene, their molecular weight will be about 2000 or 3000 more.

Polystyrenes have different applications in different industries. These materials are transformed into different shapes using different methods. Polystyrene can also be used to produce recyclable food packaging and building insulation.
