Polyurethane rigid foam insulation is the new favorite of thermal insulation and energy saving

In recent years, with the rapid development of China's building energy-saving market, polyurethane rigid foam body insulation products have been widely used in the field of building insulation and waterproofing, and have become one of the leading insulation and energy-saving products in the market.

Polyurethane rigid foam insulation material for the construction industry is an important branch of the polyurethane industry. It is characterized by a multi-purpose, and at the same time with insulation, waterproof and other functions. Polyurethane hard foam breaks down the traditional building materials with a single function, waterproof non-insulated, non-waterproof insulation, once leakage occurs in the waterproof layer, and the insulation layer loses its insulation function. Compared with other single function insulation or waterproof materials, polyurethane rigid foam has obvious advantages:

1, Polyurethane hard foam has a multi-purpose function, at the same time with insulation, waterproof, noise, vibration absorption and other functions;

2, excellent insulation performance, is currently the lowest thermal conductivity of all building materials in China (≤ 0.024, green non-fluorinated foam technology), the highest thermal resistance of the insulation material, thermal conductivity is only half of the EPS foam polystyrene board;

3, polyurethane rigid foam body continuous dense skin and close to 100%% of the high-strength interconnected wall closed-cell, with perfect impermeability. The spraying method can be used to achieve continuous and seamless waterproof insulation layer, forming a seamless roof and overall exterior wall thermal insulation shell, with excellent waterproof and impervious performance;

4. Excellent self-adhesive performance (without any intermediate adhesive material), strong bonding with roof and exterior walls, good wind resistance and resistance to wind pressure;

5, the overall spraying construction, completely eliminate the "hot section" and "cold bridge";

6, flexible gradient technology can effectively prevent the waterproof layer cracking;

7. Mechanized operation, automatic batching, uniform quality, short construction period;

8, chemical stability, long life, does not constitute pollution to the surrounding environment;

9, away from the open flame self-extinguishing, and when burned only carbonized without dripping, carbonization layer size and shape basically unchanged, can effectively block the air into the fire, stop the spread of fire, fire safety performance is good.

In addition, the properties of the polyurethane hard foam material itself have a significant impact on the safety of use of the building, insulation function, waterproof function, and must be highly valued in the selection of materials.
