Polystyrene sheets are made of styrene monomers. It was first discovered in 1839 by Edward Simon. After that, polystyrene sheets were used in World War II and various industries. In general, since 1950, the use of polystyrene has become very popular.

This material is made of about 95% air. This makes the PS large. Therefore, polystyrenes can be considered resistant to impact and pressure. These materials are very light and are used in various industries. Join us in this PetroProviders article to show you Polystyrene sheets.

Structure of Polystyrene sheets and their grade types

Polystyrene sheets are also commonly known as crystals. These materials are widely used in the construction of buildings. In addition, these sheets are also used as insulation. Polystyrene sheets are low density, have high impact resistance, and are resistant to various chemicals.

Polystyrenes are usually transparent and are used to make glass and wall insulation. This material is also suitable for use in shower enclosures and cabinets. Because they are resistant to water and moisture. In addition, it has a very low permeability to water. This allows polystyrene to be used in wet environments such as the bathroom.

One of the most important features of PS is that it can be easily produced and recycled. This allows them to be produced in different designs. In general, highly durable plastics and clear plastics can be made with polystyrene. These materials are very durable and have a long life.

Polystyrene sheets are heat resistant. These materials can also resist the light and weak acids. In addition, these sheets are thermoformed; That is, they can be converted into different shapes by heating.

Applications and Advantages of Polystyrene sheets

There are several benefits to using polystyrene. These materials are easy to produce and inexpensive. In addition, polystyrenes are very lightweight and are used in various industries. The advantages of using polystyrenes are:

  • High earthquake resistance of these polymers
  • High fire resistance of polystyrene
  • Low density
  • Being lightweight
  • Heat Resistant
  • Resistant to weak acids and alkalis
  • Resistant to various pressures and shocks
  • Resistant to light and oxidation
  • Can be used in different environmental conditions
  • Resistance to high temperatures
  • Ability to convert to different shapes
  • Proper insulation of buildings

Disadvantages of polystyrenes and sheets of this polymer

It can be easily said that every substance has advantages and disadvantages. Polystyrene also has a variety of disadvantages. These polymers are made in different dimensions and can be seen in various colors in global markets. Disadvantages of polystyrene are:

  • Low resistance to organic solvents
  • Low resistance to strong acids and alkalis
  • If chlorofluorocarbon is used to make polystyrene, it will damage the ozone layer.
  • If the sheets are painted, they will catch fire in contact with fire

Differences between XPS and EPS polystyrene sheets

XPS and EPS polystyrene

XPS and EPS polystyrene

The two most popular grades of polystyrene in construction are EPS and XPS. These two grades have various properties and are used for various purposes. For example, polystyrene sheets can be used for insulation.

In general, EPS sheets in global markets are called ionolite. This material is easily produced and can be converted into various forms. XPS sheets are also used as building insulation and electrical insulation.

EPS and XPS polystyrenes are not harmful to the environment; Because they are easily recycled and converted into various forms. EPS and XPS construction methods are different. In addition, various moldings are made to produce these sheets. These sheets are cheap but may have different prices in different markets.

EPS or expanded polystyrene is the same as General Purpose polystyrene but has been dehumidified. Polystyrenes take various forms and increase their volume as moisture escapes from them. This makes EPS very lightweight and easily portable.

XPS or extruded polystyrene has a different production method. Melted polystyrene enters the mold and after injection molding, it has a very high resistance. This material has a higher heat coefficient than EPS. In addition, XPS is used to insulate building surfaces; But for building blocks, EPS is used.

XPS has a very high resistance to impact and moisture, But it breaks under a lot of pressure. This material is more expensive than EPS and slightly heavier than EPS.

Summary of Polystyrene sheets review

In this article, we saw the types of Polystyrene sheets and their features. These polystyrenes have various properties that make them used in various industries. These features include lightweight, high impact resistance, cheapness, recyclability, and transparency.

Polystyrene sheets are usually available in EPS and XPS grades in markets. These materials have special properties and you need special conditions to use them. What do you think about Polystyrene sheets?
