The polyurethane composite panels produced by Yanghu Refrigeration are composed of upper and lower layers of color steel plates and intermediate foamed polyurethane. It adopts the world's advanced six-component online automatic operation mixing and pouring technology, which can complete the mixing process online at one time, and can be adjusted according to the requirements. On-line control and adjustment of temperature can produce distinctive high-strength, energy-saving and green building boards.

Due to its good fireproof and moisture-proof performance, it is also often used as the edge-sealing core material of composite panels of other materials. Polyurethane edge-sealing composite panels use high-quality color-coated steel plates as surface materials, continuous rock wool and glass wool as core materials, and high-density hard The foamed polyurethane is filled with tongue and groove. After high-pressure foaming and curing, the cotton is automatically dense and formed by the control of the super-long double-covered belt. Compared with the traditional hanging cotton maintenance material, it has better fireproof and thermal insulation effects and longer performance. , easy to install and elegant appearance. It is a leader in steel building envelope materials.

Generally used for roof panels and partition panels of buildings, the panels have good thermal insulation, heat insulation and sound insulation effects, and polyurethane does not support combustion, which is in line with fire safety. The combined action of the upper and lower panels and polyurethane has high strength and rigidity. The lower panel is smooth and flat, with clear lines, which increases the indoor aesthetics and flatness. It is a new type of building material with convenient installation, short construction period and beautiful appearance.

As a new type of building energy-saving thermal insulation material, polyurethane composite board has been widely used in different countries. Its use plays an important role in promoting the continuous innovation of building materials. With the modern requirements for the construction industry It is getting higher and higher, especially the use of indoor materials is more demanding, so it is a general trend to choose polyurethane composite panels.

Scope of application

As a building energy-saving thermal insulation material, polyurethane composite panels have been widely used in developed countries such as Europe, the United States, and Japan, with a penetration rate of 80%, but less than 10% in my country. As an excellent energy-saving thermal insulation material, polyurethane sandwich panel can provide an efficient solution for solving China's energy consumption crisis due to its excellent thermal insulation, fire protection and thermal insulation properties.

Polyurethane sandwich panels are widely used in large industrial plants, cold storage, garages, mobile houses, exhibition halls, exhibition halls, gymnasiums, shopping centers, airports, power plants, villas, hospitals, strata and high-rise office buildings, etc. The performance is mainly used in the roofs and walls of industrial and civil buildings.

Insulation performance

The B1 grade polyurethane composite panels produced by Yanghu Refrigeration have excellent thermal insulation properties.

The 5cm-thick composite board is equivalent to the 1m-thick concrete thermal insulation effect, and has excellent thermal insulation performance.

Polyurethane rigid foam is a new type of polymer material with excellent properties of small bulk density, low thermal conductivity, high closed cell rate and corrosion resistance.

Advantages of roof panels

The polyurethane roof panels are connected by dark nails, and the panels are closely overlapped.

The unique waterproof groove design can effectively prevent the penetration of rainwater and avoid the phenomenon of cold bridge.

The 40mm crest height greatly improves the bearing capacity of the roof panel. While ensuring the thermal insulation effect of the building, it can effectively reduce the construction cost of customers, and the roof slope can be as low as 3%.

Wall Panel Advantages

Concealed nail connection, no exposed screws on the surface, the building wall is beautiful and smooth.

Extremely high flexural bearing capacity, superior wall mechanical properties, and less reliance on auxiliary steel structures.

Excellent thermal insulation performance, reducing the cost of building indoor air conditioning units.

A variety of appearance effects, beautiful walls.

Efficient heat preservation

The composite board has the lowest thermal conductivity (≤0.022) among the organic thermal insulation materials, and the 5cm-thick polyurethane composite board is equivalent to the thermal insulation effect of 1m-thick concrete. Polyurethane composite board is an ideal thermal insulation product to achieve the goal of 75% of building energy saving in my country.

High flame retardant performance

A-grade composite board will not burn through after 1000 ℃ flame for 30 minutes.

Durable weather resistance

After more than 6 months of weather resistance test, the performance is stable and can have the same life as the building.

good dimensional stability

The compressive strength is above 120kp, and the plate has good temperature resistance and no deformation.

Low carbon and environmental protection

Polyurethane composite panels use bio-based raw materials, fluorine-free foaming, and do not use harmful substances that are prohibited or restricted by the state, and are environmentally friendly.
