Characteristics of EPS
EPS is a Highly Resource-efficient Material by Virtue of the Air Inside
The 98% Air inside EPS Products Makes it Excellent Properties
EPS products are comprised of 98% air, so they have excellent insulation and shock-absorbent properties. Furthermore, it is used in various industries because it has great lightness, processability, and durability. Also, due to it being a single material, it is easy to recycle.
Excellent Characteristics of EPS
1Insulation
As it contains a lot of air, EPS shows excellent heat and cold insulation performance.
Cold things stay cold and warm things stay warm. EPS is a collection of expanded beads that consist of tiny independent air bubbles. Since there is less air circulation in each air bubble, it is difficult for heat transfer to happen.
EPS made it possible to preserve the freshness of fish, while it was difficult to do so with wooden boxes prior.
2Shock Absorbency / Cushioning properties
The EPS independent air bubbles have excellent shock absorption. This protects the products as a cushioning material for packaging things like home appliances and delicate equipment.
3Lightweight
Extremely lightweight because the product consists of 98% air and 2% polystyrene.
4Resource Saving
EPS is made with only 2% of petroleum-derived material and 98% of air, so it is extremely resource-saving.
5Durability
EPS can retain its shape semi-permanently if it is not exposed to direct sunlight (Ultraviolet rays). For weight load durability, it can tolerate up to 5 tons per 1 square meter on its surface when loaded evenly. (expanded EPS pressure allowance in the case of 20 Kg/M3)
6Recyclability
Since EPS is derived from a single material, it has excellent recycling abilities that can easily be reused as a renewable resource (ingot, and pelletized) by just applying heat.
7Processability
It can be easily shaped by cutting it with a knife or using a heating wire.
[Usage example]
Taking advantage of the characteristics of it being ③ lightweight and ⑤ durable
With the EPS embankment construction method (GEO FOAM), it can be used instead of soil (EPS blocks 50cm thick, 1m x 2m in size) in some construction projects. It has excellent durability even after 40 years of use.

Ex) Ratio of weight for same cubic volume (1㎥) soil = 1.3 – 1.8 ton / concrete and asphalt = 2.3 ton / EPS = 0.02 ton
