Polyurethane Foam: building insulation waterproof material integration

Body construction with rigid polyurethane foam insulation is an important branch of the polyurethane industry, which is characterized by a multi-purpose timber , along with insulation, waterproofing and other functions. These products since the 1960s in Europe since the 40-year history of construction applications , some countries have passed legislation as the polyurethane insulation and waterproof construction specified timber . In recent years , with the rapid development of China's building energy efficiency market, the polyurethane foam insulation products in body building insulation waterproof fields has been widely used, has become one of the leading energy-saving insulation products market .Sellotape

As the integration of building insulation waterproof material , polyurethane foam breaking the traditional function of a single building - not waterproof insulation , thermal insulation is not waterproof , waterproof layer insulation leakage occurs once a common problem immediately lose insulation function . Compared with other single-function insulation or waterproofing materials , polyurethane foam has obvious advantages :

1 , polyurethane foam has a multi- functional , along with insulation , water, noise , vibration absorption , and many other functions.

2 , insulation performance, is all domestic building materials lowest thermal conductivity (≤ 0.024), the highest thermal resistance of insulation materials , thermal conductivity is only half of the EPS foam polystyrene board .

3 , polyurethane foam body continuous dense skin and nearly 100% of the high-intensity interconnected walls closed, with the ideal impermeability . Construction method using spray continuous seamless waterproof insulation layer to form a seamless whole roof and wall insulation shell, excellent water impermeability .

4 , super sticky performance ( without any intermediate bonding material ) , and the roof and exterior walls bond firm, wind exposed, and negative pressure good performance ; overall spray , completely eliminating the "hot " and "cold bridge" flexible gradient waterproof layer technology can effectively prevent cracking ; mechanized operations, automatic batching , uniform quality , construction of fast , short cycle .Washi tape


5 , chemically stable , long life, does not constitute pollution to the surrounding environment ; away from self-extinguishing flame and burning charring not only dripping , carbonized layer is essentially the same size and shape , can effectively cut off air to enter, to prevent the fire spread , fire safety performance.Masking tape


As the only integrated new building insulation and waterproof polyurethane foam insulation applications in the domestic construction industry is still in its initial stages. Fortunately, building insulation materials for accelerating innovation and promote the popularization and application of polyurethane foam in the field of building energy efficiency , the Ministry of Construction has established a special " promote the application of polyurethane building energy working group " in order to promote the polyurethane foam insulation waterproof material in the domestic construction energy industry applications.Wholesale masking tape
