Expanded Polystyrene Raw Material

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.
