What are the product characteristics of building insulation sandwich board polyurethane?

The prefabricated sandwich board products of Shandong Wiskind Architectural Steel Co., LTD. choose the new generation polyurethane PIR pentane B1 foam as the hard core material, which has excellent thermal insulation and fire resistance. The core material has ultra-high temperature stability and fire rating, no freon emissions, energy saving and environmental protection, can be widely used in industrial building cold storage projects.

Polyurethane for construction -- rigid insulation material

Polyurethane was first synthesized by Professor byaer in 1937. It is widely used, involving many products and a wide range of fields. In recent years, with the development of materials science and the improvement of environmental protection awareness, polyurethane products have also ushered in great development, and has become one of the leading thermal insulation materials in the market. Polyurethane rigid foam material entered China in the 1960s and was used in sandwich boards for construction as hard thermal insulation material. It triggered a revolution of waterproof thermal insulation materials and their technology in the field of building waterproof thermal insulation.

Characteristics of hard insulation materials

Polyurethane rigid foam insulation material is one of the ten new technologies mainly promoted in construction. Compared with other single-function insulation or square materials, polyurethane rigid foam insulation material has the following advantages:

1. Low thermal conductivity, excellent thermal insulation performance;

2. Low water permeability, excellent waterproof and impermeable performance;

3. Strong self-adhesive, excellent wind resistance;

4. Light quality, reduce the foundation cost;

5. Flame retardant material, both fire retardant plate;

6. Prefabricated, quick and simple construction.

In general, polyurethane hard foam insulation material has the characteristics of simple construction, reliable technical performance and reliable quality. Suitable for all kinds of industrial and civil buildings roof, wall, floor insulation, heat insulation, waterproof, etc.
