EPS Plastic Granules
Polystyrene plastic beads, after being heated and expanded, will become a compound containing Bentane gas (C5H12) in granular form, called EPS foam plastic granules. EPS foam beads have a synthetic composition of 90 – 95% Polystyrene and 5 – 10% gas-forming compounds such as Pentane or Carbon Dioxide.
Through the heating process, the EPS plastic beads will expand and then stick together. Depending on the product and purpose of use, when put into production, people will reshape the EPS foam compound.
With the common name of foam, plastic beads to make foam containers, EPS plastic beads are currently a quite commonly used material today. What properties do they have? What are the advantages and disadvantages and applications? Please follow the article below for more information:

What is EPS Plastic Granules?
EPS (Expanded Polystyrene) is another name for expanded polystyrene. EPS material is produced in granular form containing Bentane gas (C5H12) – a flammable gas.
EPS plastic molecules have a synthetic composition of 90-95% Polystyrene. Add to that 5-10% gas-forming agents such as pentane or carbondioxide. After being processed, EPS plastic beads expand, increase in size and stick together. When put into production, this material will be shaped into products depending on the intended use.
Properties of EPS plastic
EPS plastic pellets with properties such as sound insulation, heat insulation, compression resistance, etc. These properties have been tested and put into industrial production under the most rigorous testing conditions:
- EPS plastic pellets have the ability to withstand compression and are tested according to DIN 53421 standards. The surface of EPS plastic is subject to high compressive stress and is soft. Therefore, the surface is slippery and protects the products inside very well. Compression resistance increases as the plastic density increases
- EPS plastic pellets have tensile properties tested according to DIN 53430 standards. Tensile force when density increases. This is a characteristic that depends on production technology and production status. This is a different characteristic from processed foam
- EPS plastic pellets have bending properties tested according to DIN 53423 standards. Bending resistance increases with increasing density.
- EPS plastic can change its load-bearing properties by up to 90% of its shape within 24 hours. Can return to original shape after 4 weeks of testing. This phenomenon is due to air permeation into EPS particles
- The temperature only changes about 10% between -10 degrees Celsius and 100 degrees Celsius. Thanks to its very low specific heat, EPS foam has very low heat transfer ability.
- Thermal expansion coefficient does not depend on temperature and physical properties of EPS plastic. In addition, this coefficient also does not depend on atmospheric pressure
- EPS plastic does not become moldy due to the surrounding environment but can become damp when directly exposed to water. The moisture content of EPS plastic is an index that depends on density
- In addition, EPS plastic also has chemical resistance, fire resistance and can be painted on the surface
Advantages and disadvantages of EPS plastic pellets
Advantages of EPS plastic pellets
- EPS plastic beads absorb shock and withstand compression well. Therefore, they are used as packaging to protect goods, electronic devices, fragile and easily scratched materials.
- EPS plastic is highly durable, resistant to moisture, and is not affected by temperature and dirt. Therefore, EPS packaging products protect products very well during storage and transportation
- EPS plastic insulates heat and sound, helping packaging products made from this material keep food fresh and avoid condensation. Ensuring products such as seafood and vegetables are distributed and transported safely while still maintaining their original freshness and shape
- Light in weight because 90% is gas, EPS packaging is considered the lightest packaging ever
- EPS plastic is flexible and versatile because it is designed according to usage requirements to suit all types of equipment from small to large. Nowadays, with the aid of computers, EPS packaging is designed and produced in complete accordance with user requirements.
- Can be reused for certain purposes. This helps save materials and protect the environment
Disadvantages of EPS plastic pellets
Because EPS plastic is essentially a synthetic plastic, products from this plastic when released into the environment will cause serious consequences. Therefore, it affects human health as well as the living environment of animals.
Application of EPS plastic pellets
- EPS plastic pellets are used to produce foam blocks, soundproofing panels, and indoor heat insulation. These include products such as PANEL corrugated iron, wall lining, ceiling, etc.
- Production of packaging for electronic and refrigeration equipment, porcelain, and glass. Thanks to this type of packaging, it is impact resistant and protects the product extremely well
- Thanks to its heat and sound insulation properties, people produce foam boxes. These foam boxes contain vegetables, fruits, fish and seafood from EPS plastic to bring freshness to the products
- With lightweight, insulating and good damping properties. People use EPS plastic as the helmet core to bring safety and lightness to the user
- EPS plastic is also used to make seedling trays. Thanks to 90% air, the surface of EPS plastic is extremely airy. This ensures soil aeration, helping plants grow and develop better
