Familiarity with the Properties of EPS is required to produce high-quality plastic products. Expanded polystyrene (EPS) is a valuable grade of polystyrene. This material is very lightweight, insulates against moisture and sound, is resistant to heat, and has high stability.

This material is used in construction as building blocks and may one day replace cement concrete! This polystyrene is resistant to wind and various shocks. In addition, it has special features that we see in this article. In the continuation of this PETRORPOVIDERS article, join us to show you the Properties of EPS.

This polystyrene is one of the 4 grades of polystyrene. In total, there are 4 grades of polystyrene in the world; Extruded polystyrene (XPS), Expanded polystyrene (EPS), General Purpose polystyrene (GPPS), and High impact polystyrene (HIPS). These 4 grades are produced in different ways and have different applications.

One of the most important grades of polystyrene is the EPS grade. This grade is produced in different formats and has unique features. For the production of expanded polystyrene, injection molding and blow molding methods are used. This material is easily produced and recycled and is used in various industries. for example:

  • In the medical industry, EPS is used to produce sterile devices.
  • In construction, this polystyrene is used for insulation.
  • In construction, expanded polystyrene is used to produce foam blocks.
  • In the automotive industry, this polystyrene is used to produce various parts.
  • In the aircraft industry, polystyrene EPS is used to produce various and durable parts.
  • EPS polystyrene has many applications for making home appliances.
  • In the food industry, EPS polystyrene is used for food packaging.

Introducing the physical properties of EPS polystyrene

This material has unique physical properties. This makes using EPS cost-effective. This material is inexpensive and has good impact resistance. In addition, this polystyrene grade has the following physical properties:

  • This material has a good density.
  • It is resistant to various vapors.
  • It absorbs a maximum of 0.5% moisture.
  • The vapor pressure of polystyrene EPS is 0.685 bar.
  • The size of expanded polystyrene particles is about 100 to 3150 micrometers.
  • It absorbs about 0.03 to 9 percent of water.
  • ..

Introduction of mechanical properties of EPS polystyrene

This material has a high resistance to pressure and impact. It resists if polystyrene is exposed to high-pressure conditions; Because it has a large volume, it can withstand a lot of pressure before breaking. In general, the Proprties of EPS depend on density, particle size, and environmental conditions. If the density of this material increases, its mechanical properties also improve.

In the EPS production process, this material is molded in different ways. This, after expansion, becomes impermeable to water. It floats in water and can withstand moisture. It should be noted that this material is permeable to various vapors. This material is also resistant to rising temperatures.

Properties of EPS vary according to the density of the material. For example, if the density of this material is higher, it will be more resistant to impact and pressure. In addition, manufacturers must provide the best information from EPS so that customers can have accurate specifications of EPS polystyrene.

Electrical and chemical properties of expanded polystyrene

chemical properties of EPS

It is very resistant to temperatures around 73 degrees Fahrenheit. The dielectric strength of this material is approximately 2 kV / mm. To produce EPS molds, the necessary standards are observed to make the best polystyrene.

This material is resistant to chemicals; For example, weak acids and weak alkalis do not affect EPS. It is also resistant to aqueous solutions and does not react. It should be noted that this material is not very resistant to organic solvents.

This substance combines with various compounds and makes them resistant to bacteria. If expanded polystyrene is exposed to sunlight, it will be damaged and the top layer will break! In addition, it may be damaged if exposed to direct UV light. This material is fireproof, but if it is in direct contact with fire, it will shrink and be damaged!

Temperature properties of EPS polystyrene

This material is resistant to rising temperatures; In addition, it is interesting to know that the composition of this polystyrene is composed of 98% air! This material has low thermal conductivity and is heat resistant. In addition, the Properties of EPS can be changed by adding different materials.

  • This material is resistant to temperatures up to 118 ° C.
  • This material boils at a temperature of 220 ° C.
  • To produce a polystyrene flame, its temperature must be raised to 285 degrees Celsius!
  • This material has a fixed shape at a temperature of 78 ° C.
  • It should be noted that this material softens at temperatures above 70 ° C
  • The esteemed capacity of this material is 1210.
