XPS foamed board, has a perfect closed-pore alveolate structure.
Its density, water absorption, coefficient of heat conducting and
the coefficient of steam pervasion are all lower than those of
other board heat preservasion materials
They have the characteristics of strong intensity, light material,
airtight, anticorrosion, aging resistance, low cost, etc.
It has been widely used in the fields of heat preservation and heat
insulation in the construction industry, frost resistance of the
highway, railway, airport, square and household fitment. It is the
generally acknowledged and the best heat preservation material in
the market at present.
