Description
Polyurethane foam sandwich panel is fit for the projects which
require strict warmth. Polyurethane core material is considered to
be the best in keeping warm and thermal insulation.
The Polyurethane block material is combined with metal plates when
it is steady after frothing. 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.
The characteristics of polyurethane foam sandwich panel (PU
sandwich panel):
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
℃.
