Expanded Polystyrene (EPS) raw material is a versatile product known for its lightweight yet durable properties. EPS is primarily composed of polystyrene beads that have been treated with pentane gas, allowing them to expand up to 50 times their original size when heated.

This results in a material that is 98% air, making it highly effective for applications requiring insulation and cushioning.

EPS raw material is widely used in various industries, including packaging and construction. It provides excellent compressive strength of 0.7 kg/cm² and a flexural strength of 2.5 kg/cm², making it suitable for use in protective packaging, insulation boards, and even in technical products like bicycle helmets.

Expandability (time): 50-85
Compressive strength: 0.7 kg / cm2
Flexural Strength: 2.5 kg / cm2

EPS is an abbreviation for Expanded Polystyrene. The raw material used for EPS are small polystyrene beads that have been allowed to absorb 4-7 % pentane gas. The pentane gas is what makes the material expand when heated.

EPS can expand up to 50 times the original size. This means that the final product contains around 98% air. Most of the pentane gas is released during the manufacturing if EPS and is replaced with air.

Released pentane gas will not affect the ozone layer. EPS is suitable for disposable packaging, but is also well suited for technical products with higher density, for example bicycle helmets. EPS can be found in a variety of different colours.

As an eco-conscious choice, the pentane gas used during the expansion process has no harmful effects on the ozone layer, adding to its appeal in modern applications.
