What are the characteristics of polyurethane hard bubble waterproof and insulation integrated board

The polyurethane hard bubble waterproof and insulation integrated board has the characteristics of high efficiency waterproof and insulation, fire safety, lightweight and high strength, durability and stability, environmental protection and energy saving, convenient construction, and strong adaptability. The specific analysis is as follows:

Efficient waterproof and thermal insulation: The closed cell rate of polyurethane hard bubbles is as high as more than 95%, and the water absorption rate is extremely low (≤1%), forming a dense and impermeable layer, effectively preventing moisture from penetration. At the same time, its thermal conductivity is as low as 0.018-0.024W/(m·K), which is 1/2 to 1/3 of traditional insulation materials, which can significantly reduce the thickness of the building's outer enclosure structure and increase the indoor use area.

Excellent fire safety performance: Polyurethane hard bubbles have become flame retardant and self-extinguishing materials after adding flame retardant. The softening point reaches more than 250℃. They do not flow or drip at high temperatures. When burning, carbon deposits form on the surface to effectively isolate the flame spread and produce no harmful gases. They comply with the national A-level fire protection standards.

Lightweight, high strength and durability: The plate is light in weight, and the 40mm thick plate weighs only about 2.4kg per square meter, which can reduce the construction load; the compressive strength is ≥300KPa, which can adapt to various roof bearing requirements; the closed-cell structure is stable, with strong anti-freeze and thaw and aging performance, with a service life of more than 50 years, and low maintenance cost.

Environmental protection, energy saving and convenient construction: Fluorine-free foaming technology is adopted, non-toxic and pollution-free; construction adopts mechanized spraying, with high efficiency (800-1,000 square meters per day), simplified process, saving 80% of construction time; strong adhesion to concrete, metal, wood and other base surfaces, forming a jointless whole to avoid hidden dangers of water skewers.

Adapt to complex structures and versatility: Liquid materials have good fluidity, can penetrate the base voids, and firmly bond to plane, curved surface or special-shaped structures; integrate waterproofing, heat insulation, heat insulation, sound absorption and other functions to meet different engineering needs.
