● Good thermal insulation. The thermal conductivity is a weighted average of pure EPS thermal conductivity (108 cal/m.h. degree ) and air thermal conductivity (about 90 cal/m.h. degree ).

● Anti-aging, corrosion performance. Except for prolonged exposure to high energy radiation, the product has no obvious aging. Can withstand many chemicals, such as dilute acid, dilute alkali, methanol, lime, asphalt and so on.
