20 Years Temperature Resistant Polyurethane Sandwich Panel 50-200 Mm Thickness

Product Description:

Features:

Our product possesses several remarkable characteristics that make it ideal for construction purposes:

Polyurethane has incredibly low thermal conductivity, typically between 0.018 and 0.024 W/(m · K), which is much lower than other traditional insulation materials. The closed cell structure of polyurethane reduces heat conduction, convection and radiation, therefore maintaining a comfortable building temperature throughout the year, reducing energy consumption and achieving energy-saving and emission-reduction.

The sandwich panels made from polyurethane can have different fire ratings depending on the application of flame retardants. The fire ratings can range from B1 (flame retardant) to A2 (non-flammable). The panels can effectively delay the spread of fire, inhibit the spread of flame and reduce smoke release, providing valuable time for evacuation and fire rescue, improving the building's fire safety.

Polyurethane's hydrophobic nature coupled with its closed-cell structure makes it resistant to water penetration. The sandwich panels, protected by the outer metal sheet, can effectively resist rain, snow, and humid air erosion, preventing water from entering the interior of the temperature retaining core material. This prevents thermal insulation performance decline, mold, rot and other moisture-related issues, ensuring long-term stability of the thermal insulation system.

The upper and lower layers of sheet metal provide enough strength for the sandwich board to withstand large external forces like wind loads, snow loads, and the weight of personnel and equipment. The polyurethane core material gives the sandwich board elasticity and toughness, ensuring it is not easily deformed or damaged when subjected to external forces, maintaining the building's stability.

Polyurethane sandwich boards have a good barrier effect on sound transmission, which can effectively reduce the interference of external noise on the indoor environment, providing a quiet and comfortable living and working space. The sound insulation effect relies on the thickness and density of the sandwich board, with the insulating performance of thick and moderate density sandwich boards being better.

Polyurethane sandwich panels are light-weight, have standardized sizes and specifications, making them easy to handle and install. There are a variety of installation methods available, such as splicing, anchoring, etc. This makes installation quick and cost-effective, effectively shortening the construction period.

The metal sheet used in the sandwich board comes in a variety of colors and surface treatments like galvanized and color coating, meeting different architectural styles. Metal sheets and polyurethane cores have good durability, which can resist natural factors such as ultraviolet light, chemical substances, temperature changes, and extend the service life of the boards.

Applications:

Polyurethane sandwich panels have a wide range of applications in various types of buildings and facilities. Here are some examples of the application fields:

Polyurethane sandwich panels are widely used in industrial plants, warehouses, logistics centers and other buildings. For industrial plants, they can provide stable temperature and humidity conditions for the production environment, reduce heat exchange, reduce heating and cooling costs, and meet the requirements of industrial production on building strength and fire performance. In warehouses and logistics centres, polyurethane sandwich panels protect goods from changes in temperature and humidity, ensuring quality.

Polyurethane sandwich panels are also used in commercial buildings such as shopping malls, supermarkets, hotels, office buildings and other commercial places. In shopping malls and supermarkets, they help to maintain a comfortable indoor shopping environment and reduce energy consumption. In hotels and office buildings, they can provide good sound insulation, thermal insulation and fire protection performance, creating a high-quality environment for customers and office workers.

For residential buildings, polyurethane sandwich panels are used for external wall insulation, roof insulation and indoor partition. In terms of external wall insulation, they can effectively improve the residential thermal insulation performance and reduce energy consumption. In the insulation of the roof, they can protect the roof structure and extend the service life of the waterproof layer of the roof. When used for indoor partition, they are both beautiful and can play a certain role in sound insulation.

The construction of cold storage is one of the important application fields of polyurethane sandwich panel. Its excellent thermal insulation performance can ensure the stability of the temperature in the cold storage, reduce the energy consumption of refrigeration equipment, and ensure the storage quality of refrigerated and frozen goods. At the same time, the moisture-proof and antibacterial properties of the sandwich board are also conducive to maintaining the sanitary environment of the cold storage.

Polyurethane sandwich panels are also used in agricultural greenhouses, agricultural products warehouses and other facilities. In the greenhouse, they can adjust the indoor temperature, humidity and light to create a suitable environment for crop growth. In the agricultural products warehouse, the freshness of agricultural products can be maintained and the storage period can be extended.
