What are the performance characteristics and advantages of thermal insulation polyurethane sandwich panels?

In recent years, with the rapid development of my country's building energy-saving market, polyurethane thermal insulation sandwich panel products 
have been widely used in the field of building thermal insulation and waterproofing, and have become one of the excellent thermal insulation and 
energy-saving products in the market. It is also widely used for external insulation of exterior walls. It is a new type of building energy-saving 
technology. After being applied in engineering examples, the advantages of this technology are very obvious.

Thermal insulation polyurethane sandwich panel is a kind of thermal insulation material with excellent thermal insulation performance. It is a plate with
 thermal insulation performance made of polyurethane through a certain processing technology. Once launched, it will be supported and favored by 
consumers by virtue of its thermal insulation performance, bringing you a different thermal insulation experience. The thermal insulation polyurethane 
sandwich panel has strong deformation resistance, is not easy to crack, and the finish is stable and safe.
 Nowadays, with the continuous development and improvement of polyurethane thermal insulation sandwich panels, the application of polyurethane 
thermal insulation sandwich panels has penetrated into our lives. Such as: automobile production, food and food processing, medical and health, 
construction machinery, electronic equipment, construction, furniture, textiles, clothing, shoes and hats, synthetic leather, printing and packaging, 
sports and fitness industries have a large number of applications. With the advancement of science and technology, 
polyurethane has gradually been well applied in our aerospace and defense industries. 1. Polyurethane rigid foam sandwich panel is a multi-purpose 
material with various functions such as heat preservation, waterproof, sound insulation, vibration absorption, etc.

  2. Good heat insulation. Among all the insulation materials currently in use, the thermal conductivity of polyurethane composite board is low. 
Because the heat insulation board has excellent heat insulation performance, under the same heat insulation requirements, the thickness of the 
building's peripheral structure can be greatly reduced. Thereby increasing the indoor use area of the building.

  3. Strong adaptability to the deformation of the main structure, good resistance to cracking and deformation. Stable chemical properties, long 
service life, and no pollution to the surrounding environment. The open flame will automatically go out, and it will carbonize without dripping when 
burning. The size and shape of the carbonized layer are basically unchanged, which can prevent air from entering, prevent the spread of fire, and 
have good fire resistance.

  4, strong durability, long service life, polyurethane material has a stable pore structure, basically closed-cell structure, not only has excellent 
thermal insulation performance, but also has good freeze-thaw resistance and sound absorption. The various constituent materials of polyurethane 
external insulation system have chemical and physical stability.

  5. Good environmental protection performance. Polyurethane board used in exterior wall insulation system is a kind of insulation material with high
 chemical stability. It has excellent acid resistance, alkali resistance and heat resistance. It will not produce harmful gases, nor will it cause harm to the 
environment. It is an environmentally friendly insulating material.

  6, good water tightness. Polyurethane material has excellent waterproof and moisture-proof performance. The material does not contain water and 
has extremely low water absorption. It can well prevent the infiltration of water and water vapor and keep the wall in a good and stable heat 
preservation state. Other protective materials are difficult to achieve. Rigid foam polyurethane exterior wall surface without seams, holes, no doors 
and windows. It has good waterproof performance and can prevent rainwater from entering the room and causing danger.

  7. There will be no condensation on the wall. Condensation in walls or protective layers is harmful. During the drying process of the newly-built wall,
 or under winter conditions, when a large amount of indoor water vapor migrates outward, the wall will be blocked by rigid polyurethane. There is no 
possibility of condensation in the wall. When the indoor humidity is low and the indoor wall is in good condition, condensation caused by water vapor 
migration in the wall can be avoided.

As a kind of building thermal insulation material, polyurethane thermal insulation sandwich panel breaks the problems of traditional building materials 
such as waterproof, heat preservation and non-waterproof. Once the waterproof layer leaks, the insulation layer will lose the common insulation 
problem. Compared with other single-function thermal insulation or waterproof materials, thermal insulation polyurethane sandwich panels have 
obvious advantages.
