Styrene and polystyrene have different applications in different industries. These are similar but have differences in features and applications. Styrene and polystyrene are used to make thermoplastic materials. In addition, Styrene and polystyrene are used to produce elastomers, heat and pressure-resistant resins, and a variety of polymers.

These two substances are mainly produced all over the world and have advantages and disadvantages. Plastics are usually made of Styrene and polystyrene; Therefore, higher quality of these materials will increase the quality of plastics. In this PetroProviders article, join us to introduce you to the similarities and differences between Styrene and polystyrene and their uses.

Full introduction of styrenes

Styrene was first produced from the Styrax tree. This material is used to produce polymeric materials around the world. Various researches have been done for better production of styrene in the world. For example, the German chemist Edward Simone first discovered styrene in 1839 and was able to produce styrene using oil.

Styrene, along with ethylbenzene, is used in a variety of commercial applications. These materials are produced by active polymerization or suspension methods.

Styrene is used to make polystyrene. Thus, 50% of all styrene produced in the world is used to produce polystyrene. In addition, 20% of styrenes are used to produce elastomers. About 15% of styrene is used to make ABS copolymers and about 10% for SAN. 5% of the styrene produced in the world is also used to make expanded polystyrene.

Full introduction of polystyrenes

Polystyrene is one of the most important chemicals used in the production of plastics in various industries. This material was used by the Germans in World War II to build various bridges and plastics. This material is produced by the polymerization of styrene. It is very inexpensive, usually transparent, temperature resistant, and heat resistant. This material has dielectric properties and is also used to produce electrical insulation products.

The structure of polystyrene, as its name implies, is the accumulation of thousands of styrene monomers. This material is easy to produce and easy to recycle. In the structural composition of polystyrene, thousands of styrene monomers are bonded together in hydrocarbon chains.

These chains have strong links and good resistance to pressure and heat. The molecular mass of polystyrene and styrene are the same; 108 g/mol is the sum of the masses of hydrogen and carbon in the hydrocarbon structure.

Different applications of Styrene and polystyrene

PS uses

PS uses

As mentioned, styrene is used to make polystyrene. Therefore, the structural formula of styrene and polystyrene is the same. For this reason, the applications of styrene and polystyrene can be considered similar.

Polystyrene is used to make electrical insulation, wound adhesives, refrigerator rubbers, and home appliance protectors. In addition, polystyrene is used to produce the following products:

  • Manufacture of hull
  • Construction of aircraft fuselage
  • Manufacture of electronic devices
  • Making food packaging
  • Making toys
  • Making models and plastic cups
  • Making small glasses
  • Making different dishes
  • Making transparent packaging boxes
  • Manufacture of medical products
  • Making tiles
  • Construction of building insulation
  • Making construction foams
  • Manufacture of durable products in industries
  • Manufacture of auto parts
  • etc…

The main differences between Styrene and polystyrene

Styrene and polystyrene Structures

Styrene and polystyrene Structures

These materials are very similar; The difference is in the method of production. The molecular structure of styrene and polystyrene is very similar but different.

Polystyrene has more resistance than styrene. Polystyrene is easily produced and recycled; But to produce styrene, different standards of chemical reactions must be observed. Polystyrenes are resistant to high pressures. It should be noted that polystyrene and styrene have harmful chemical and physical properties; These chemicals can easily damage the human respiratory system.

The applications of polystyrene are much more than styrene. Polystyrene is used to produce small and large plastic products. Styrene is usually produced in one type, But polystyrene is produced in 4 different grades.

The different grades of polystyrene are General Purpose Polystyrene (GPPS), High Impact Polystyrene (HIPS), Extruded Polystyrene (XPS), and Expanded Polystyrene (EPS). These 4 grades of polystyrene are used in various industries. The most important difference between these grades is their production method. Different molding methods are used to produce different types of polystyrene.

A summary of reviews of Styrene and polystyrene and their differences

Plastics are usually made of Styrene and polystyrene; Therefore, higher quality of these materials will increase the quality of plastics. Polystyrene has more resistance than styrene. Polystyrene is easily produced and recycled; But to produce styrene, different standards of chemical reactions must be observed. Polystyrenes are resistant to high pressures.

Polystyrene is used to make building insulation, medical products, plastic rubbers, and home appliances. Styrene is much more toxic than polystyrene! The toxins in styrene cause severe damage to the eyes, brain, and skin. Try never to burn plastics to prevent styrene and polystyrene chemicals from entering the body.
