It belongs to the same chemical family as other better known gases like methane, ethane, propane and butane which are used as heating fuel. Pentane released during the EPS manufacturing process quickly turns into carbon dioxide and water in a photochemical reaction. It does not contain chlorine and so does not harm the ozone layer like CFCs or HCFCs.
Steam is used as energy in the manufacturing of EPS. The steam itself is produced in boilers mainly using natural gas as fuel. Water consumption used in the manufacture of EPS is very low. The water is reused many times in the process. There is no solid waste generated during the EPS manufacturing process. Waste and off-cuts are easily put back into the production process. No material is wasted and clean used packaging can be recycled into new product using this method. There is no pollution to the surface or underground water supplies near an EPS plant because atmospheric and liquid emissions are very low during the manufacture of EPS.
Lightweight: the lightweight properties of EPS bead makes it easy to transport and allows safe use on site
Low Water Absorption: EPS bead does not absorb moisture and its thermal properties are not affected by damp, humidity or moisture. Its closed cell means it cannot absorb water and bead will maintain its shape, size, structure and appearance.
Ageing Resistance: all the above properties are retained over the materials life and will last as long as the building itself.
