About EPS
Expanded PolyStyrene
Expanded polystyrene (EPS) is a rigid closed cell plastic foam resin made from Polystyrene derived from crude oil. EPS is Polystyrene Foam that uses Pentane gas (C5H12) as a blowing agent. During the material production process called "Polymerization" the polystyrene resin granules impregnated with the blowing agent. The EPS production process begins by pre-expanding the EPS bead. Expansion with steam will increase bead volume 40 - 50 times, depending on the required final density. Next, an aluminum mold is filled with expanded bead and heated with steam until they fuse together. The part is cooled with vacuum and ejected from the mold.
Other EPS Facts
- EPS is recyclable.
- EPS does NOT contain Chlorofluorocarbons (CFC) or formaldehyde.
- EPS does NOT contribute to the growth of mold or mildew.
- EPS is considered to be no more toxic than Douglas Fir wood under the worst case fire scenario.
- EPS is subject to attack by petroleum based solvents.
- EPS is inert and stable.
- EPS does not produce methane gas or contaminating leachates.
- EPS manufacturing uses little energy and creates little pollution.
- EPS products save resources by reducing energy consumption through insulation systems.
- EPS is able to withstand the abuse of temperature cycling, assuring long-term performance.
