pu sandwich panel

 is fit for the projects which have serious require of keeping warm. Polyurethane core material is considered to the best material in keeping warm and thermal insulation. 
The Polyurethane block material become steady after it froth

, then combining with metal plates. The characteristics of this technique are:

 the polyurethane froth, after this chemical reaction is stable, we cut the 

polyurethane into pieces which with different thickness. The polyurethane 

sheet material has stable physical performance, 

it can combine with pre-painted hot galvanized steel sheets or s

tainless steel sheet, the surface is smooth and the whole performance is excellent.

2.   Characteristics

1.sandwich wall panels(the abbreviation of polyurethane is PU sandwich panel) have charateristics of high load intensity, small water-absorptive, and the stability in either low temperature or the high temperature is good, the service life is long, thermal insulation performance is outstanding

 and so on.

2.Good supporting, heat resistant, sound-insulated, sound absorption, light quality, non-toxic,odorless, green environmental protection.

3.Structural insulated panel system can cementation with the steel paltes, the cements, the fiberboards, the bricks and many kinds of  materials very strongly, in usual situation, it would not fall off and still strengthen its thermal insulation and waterproof effects.

4.the unique produce foaming craft made the products have exquisite and even abscesses,  the thermal conductivity is low, the size stability is good, is very suitable for both of the low pressure and the high pressure construction.

5.Polyurethane foam plastucs thermal stability is quite good, when the temperature is lower than 120°C the volume and the intensity have no obvious change, its thermal conductivity is small, when the desity is 0.03kg/m3, the heat conductivity is only 63J(m.h.k)(15cal/m.h.k).

4.Product Technical Advantages 
  1. Tailor made by customers' requirement in terms of colours, thickness, density, 

      and composite alteration.
   2. A class fire-resistance( 650.C)fire-resistance period(120min)
   3. Excellent thermal & sound insulation and energy saving performace
   4. Hidden installation with no visible bolt fixing
   5. Outstanding integrity and nice looking
   6. Fast and easy installation
   7. Excellent durability and strength
   5. Anti oxidation

Our factory mainly  produce 3  kinds of sandwich panel(PU sandwich panel,rock wool sandwich panel, glass wool panel)

1,PU sandwich panel

In terms of material proportioning and technical output of our company PUR product, six-component mixed pouring technology, allowing on-line autimatic operation which is the most advanced in the globe is adopted to take the lead in achieving six-component continuous foaming in China and finish proportioning process on line at time; on the other hand, the formula can be adjusted in in accordance with the environmental change to match with air-entrapping mixing unit to bring more well-distributed materials and finer foams for the purpose of producing high-strength, energy-saving and environment-friendly building boards.

 2.Rock wool sandwich panel

Rockwool sandwich panels manufactured by our company are made of a high quality rockwool. turning 90 degrees after cutting, assure the fiber direction perpendicular to the sheet to increase the strength. spraying the high-intensity fire-proof adhesive to the surface of the core and the sheet ensure that it won't be cracking after a long time. on the other hand, we use the polyurethane side sealing technology which greatly improves the insulation water proof performance and general quality.

3.Glass wool panel

 Our glass wool panels are made of high quality pure melting silica, which can bare of over 350 degree and have very good performance. turning 90 degrees after cutting, assure the fiber direction perpendicular to the sheet so as to increase the strength. spraying the high-intensity fire-proof adhesive to the surface of the core and the sheet, ensure that it won't be cracking after a long time. on the other hand, we use the polyurethane side sealing technology which greatly improves the insulation waterproof performace and general quality.
