Polystyrene Sheets (EPS Sheets)
One of the most important and practical materials widely used today across various industries—including construction and packaging—is polystyrene sheet (EPS sheet).
Polystyrene sheets are used in different parts of buildings such as walls, ceilings, and more due to their valuable features, including:
-
Extremely lightweight
-
Excellent resistance to impact and pressure
-
Outstanding sound and moisture resistance
-
High resistance to chemicals
-
Resistance to corrosion and insects
In fact, ceiling and wall EPS blocks are produced from the main EPS block and are widely utilized in construction.
Production of Polystyrene Sheets (EPS Sheets)
The production of polystyrene sheets involves three main stages:
Pre-expansion Stage
In the first step, known as pre-expansion, the raw material (styrene) is expanded by injecting steam into the expander, increasing its volume to more than 50 times its original size.
Conditioning Stage
In the second stage, during the polymerization process, two blowing agents—pentane and carbon dioxide—are used to expand and foam the raw material. The material is then left to rest for 6 to 12 hours to reach thermal and pressure equilibrium and complete its maturation phase.
Molding Stage
The cooled beads are transferred into molds and reheated with steam, allowing the EPS beads to fuse together and take the form of the main polystyrene block.
During production, the blowing agents pentane and carbon dioxide create millions of air-filled cells within the polystyrene structure. As a result, more than 90% of the final product’s volume is composed of air, while the raw material accounts for less than 10%.
In the next phase, the cooked and expanded material is cooled and transferred to storage silos to prepare it for molding. The material is then poured into the mold and shaped into the main EPS block using steam. These blocks typically measure 1x2x2 meters. Finally, the blocks are moved to well-ventilated storage areas with controlled temperature.
Production of EPS Packaging Sheets
The production of EPS packaging sheets is an efficient and cost-effective method for protecting delicate goods during transportation and storage. These sheets are made from expanded polystyrene (EPS), which offers extremely low weight along with excellent shock-absorption and thermal-insulation properties.
Thanks to their flexibility and easy cutting capability, EPS packaging sheets are widely used in various industries—including electronics, home appliances, and the food industry—and play an essential role in maintaining the safety and integrity of products.

Another type of EPS sheet is the 10 cm EPS sheet, which has a wide range of applications. This sheet is produced and offered in various sizes and densities to meet different project requirements.
Main Applications of EPS Sheets
The unique features and properties of EPS sheets have made this material highly versatile, with numerous industrial applications, gaining significant attention in recent decades. Some of the most important applications of EPS sheets include:
EPS as Thermal and Acoustic Insulation
Expanded polystyrene (EPS) is well-known as an excellent thermal insulator, effectively preventing the transfer of heat and cold. For this reason, the use of EPS in the construction industry continues to grow.
However, using EPS alone as sound insulation is not recommended. If EPS is intended for acoustic insulation, in addition to selecting the proper thickness and density, it should be used in combination with open-cell insulation materials (such as polyurethane foam or rock wool) to achieve optimal soundproofing results.
EPS in Cold Storage and Refrigeration
EPS is also an excellent temperature insulator, making it ideal for use in industrial refrigerators and cold storage facilities. Typically, high-density EPS sheets with a thickness of 5 to 10 cm are installed beneath the walls of industrial refrigerators. This not only prevents cold from escaping through the refrigerator walls but also minimizes the impact of external temperatures on the internal environment. For effective thermal insulation in industrial refrigerators, it is strongly recommended to use high-density EPS, as its compact structure enhances the insulation performance.
EPS and Lightweight Construction
In addition to being widely used as an insulating material in the construction industry, EPS is extremely lightweight. This property makes it highly popular in building construction. As a result, EPS is often used as 3D panels in walls and ceiling blocks in building projects.
However, it is important to ensure that fire-resistant and standard-compliant EPS is used for these applications. Additionally, construction regulations and the recommendations of supervising engineers should be carefully followed when incorporating these products into building structures.
EPS in the Packaging Industry
Since EPS is a lightweight material, it is widely used for packaging purposes. EPS is commonly employed to protect fragile and sensitive items such as ceramics, glassware, electronic components, automotive parts, and more.
EPS in Decoration and Set Design
Although industrial EPS is often cut using hot-wire methods, it can also be easily shaped with simple cutting tools such as cutters, coping saws, and similar instruments. Additionally, high-density EPS has good sanding properties, making it easy to smooth and shape.
These features, combined with its affordable cost, have made EPS a popular material for decorating television programs, movies, and theater sets, attracting many set designers and decorators to use it in their creative projects.
EPS and Craft Making
One of the notable features of EPS is its easy cuttability, which makes it ideal not only for decor and model making but also for craft projects for children in schools. Some textbooks even reference EPS for craft workshops and creative activities.
Typically, 2 cm, 3 cm, and 5 cm high-density EPS sheets are used for crafting purposes. However, when working with EPS, it is important to note that the material is sensitive to many types of glue. To attach EPS pieces, it is recommended to use special EPS glue or wood glue.
