PU polyurethane color steel sandwich panels
Rigid polyurethane foam has good heat resistance, and its volume and strength will not change obviously when the temperature is lower than 120 ~C. Its thermal conductivity is small. When the density is 0.03kg/m3, the thermal conductivity is 63J/(m.h.k) (15ca1/m.h.k)

Light weight: 10-14 kg/m2, equivalent to 1/30 of the brick wall insulation insulation: thermal conductivity of high strength: can be used as envelope structure, load-bearing structure, bending and compression resistance: general housing without beams and columns. Bright colour and lustre: No surface decoration is required. The anticorrosive coating of the coloured galvanized steel sheet can be maintained for 15-30 years. According to flexibility and speed: the construction period can be reduced by more than 40%.
Oxygen index: (OI) 34 (Provincial Fire Products Quality Supervision Station). Temperature limit: -50 C - +120 C
This product is widely used in: purification plant ceiling, envelope and purification products; construction of villas, industrial plants, warehouses; cold storage, air conditioning system; the original building sandwich room; long-span roof ideal materials.
