XPS foamed board, has a perfect closed-pore calceolate

structure.

Itsdensity, water absorption, coefficient of heat conducting and thecoefficient of steam pervasion are all lower than those of other boardheat preservations materials.

They have the characteristics of strong intensity, light material, airtight, anticorrosion, aging resistance, low cost, ect.

It has been widely used in the fields of heat preservation and heatinsulation in the construction industry, frost resistance of thehighway, railway, airport, square and household fit ment .It is thegenerally acknowledged and the best heat preservation material in themarket at present.
