Polyurethane Sandwich Panel

详情

The technical process is as follows:
1. The polyurethane froths;
2. Cut the polyurethane into pieces of different thickness when the chemical reaction is stable;
3. Combine the polyurethane sheet (with stable physical properties) with pre-painted hot galvanized steel sheets or stainless steel sheets;
4. Make sure the combination surface is smooth and the process is finished.

Characteristics:
1. High load intensity, low water absorption, long service life, outstanding thermal insulation and great stability in low and high temperature.
2. Lightweight, non-toxic, odorless and eco-friendly; good supporting, heat resistance and sound insulation.
3. Can cement with steel plates, cements, fiberboards, bricks and many kinds of materials and normally would not fall off with great thermal insulation and waterproof properties.
4. The unique foaming craft enables the panel to have low thermal conductivity and good size stability. The panel is suitable for construction in low or high pressure.
5. Light weight: ****4kg/M2;
High thermal stability: no obvious change of volume and intensity when the temperature is lower than **0℃;
Low thermal conductivity: *3J (m.h.k) (*5cal/m.h.k) when the density is 0.*3kg/m3.
6. The installation is convenient and flexible with no need of large-scale lifting devices to shorten the construction period and lower the cost.
7. Great temperature-resistance: no deformation from ***0℃ to **0 ℃.
