Product Description
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: 10-14kg/M2;
High thermal stability: no obvious change of volume and intensity when the temperature is lower than 120°C;
Low thermal conductivity: 63J (m.h.k) (15cal/m.h.k) when the density is 0.03kg/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 -110°C to 120 °C.

Surface of Panels: to be plating 0.4mm, 0.5mm or 0.6mm pre-painted white hot galvanized steel sheets or stainless steel sheets and PVC protected films.
Applications:
It can be widely used as the structural material and heatproof material in petroleum industry, chemical industry, construction, packing, refrigeration, m industry, space industry, aviation, transportation, industrial model design and so on.
Plant and equipment:
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.
Company Profile
Changzhou Yuyan Refrigeration Equipment Company Limited is a cold storage plant and the overall energy efficiency solutions provider and one of the energy-saving manufacturers of cold storage panel. The cold storage panel is using polyurethane materials for the inner and the surface of panel using pre-painted galvanized steel sheet , 3 0 4 stainless steel sheet or aluminum embossed stucco sheet which can effectively reduce the heat generated due to the temperature difference between inside and outside and to achieve maximum efficiency refrigeration system. The scientific connecting method for the panel is by tongue-and-groove dry joint by cam lock which will have the good sealing performance and easy accessibility to ensure the excellent aesthetics for the cold storage installation.
Changzhou Yuyan Refrigeration Equipment Co., Ltd. has the extensive experience and the professional technicists in the design, construction, installation and after-sales service which will ensure the quality for each constructed cold storage project from us and we can provide a full range of services to the customers with the energy-saving insulation system for the design, the construction, the production and the maintenance of each cold storage project,ensure the quality of each polyurethane insulation board produced.
Changzhou Yuyan Refrigeration Equipment Co., Ltd. will be honest to make friends, to the quality of survival, reputation and development, efforts to establish a reliable and stable cooperative relationship with domestic and foreign customers and become good partners, and seek common development.
