Polyurethane foam is the beginning of the last century occurred in the construction market in Europe , and quickly became an important material for construction , insulation and waterproof , with the continuous development of China 's construction industry, the rapidly expanding energy market , the application of rigid polyurethane foam construction materials is becoming an important symbol of the modern enterprise .
Polyurethane foam is the polymerization reaction by a rigid polyether polyol with an isocyanate polymer occurring organic materials, which commonly known as white foam polyether polyol material , commonly known as black isocyanate material , polyurethane foam materials appear to break the problem of building traditional single function , a versatile new materials. Polyurethane foam materials are waterproof and insulation properties, application in refrigeration, insulation, solar and water and other areas in the industry. With the development of the times, the material is polyurethane foam insulation and construction trends currently applied waterproof material , so it is necessary to polyurethane foam materials used in the construction to take attention attitude towards the adoption of rigid polyurethane foam materials construction companies working to promote the application of science and technology and management level.

High performance building insulation system is bound to depend on the performance greatly improved insulation , rigid polyurethane foam is one way of building high performance external wall insulation system to the . It has good physical properties, acoustical properties, chemical properties and electrical properties , the thermal conductivity is only about 40% of polystyrene foam . And has sufficient strength and bonding capacity , is an excellent insulation material , and then the construction of rigid polyurethane foam molding is very convenient , the price is also cheap, so it 's a very wide range of applications for industrial and civil construction , commercial building material structure of the building , such as cold storage building walls, roof , floors, ceilings , etc. .

Polyurethane foam insulation is the best energy-saving materials , the performance indicators are better than the traditional XPS, EPS insulation system . Such insulation system technology has been the leaders , experts, national attention provinces .Wholesale masking tape


In our construction projects, rigid polyurethane foam roof insulation waterproofing and insulation of cold storage areas , greenhouses, grain and others have used, and most of them have hundreds of years of history. Which the roof, cold storage etc. developed a corresponding construction application of technical specifications . With the development of improved energy requirements and rigid polyurethane foam insulation technology, rigid polyurethane foam building insulation industry has drawn increasing attention, applied technology research in the field of external wall insulation also started in recent years , Beijing , Jilin to have a lot of engineering examples . Promote the use of rigid polyurethane foam insulation system is the inevitable trend of high-performance requirements of high performance insulation system is bound to depend on greatly improved thermal performance of insulation materials . Promote the use of rigid polyurethane foam is determined by its own high-performance , summary, from internal and external two ways : rigid polyurethane foam promote the use of cool has a certain inevitability , it is building insulation external wall insulation sectors, especially in terms of the next few years there will be a larger development.

At present, China is the world's largest producer of refrigerators in 1998, consumption of rigid foam 80,000 to 100,000 t, used oil pipelines, chemical storage tank insulation materials and industrial equipment accounted for 15% ; building is hard another large field of application of polyurethane foam , 2000 PUR rigid foam construction industry consumes up to 70 000 t or more. Due to the rapid development of China's construction industry for building insulation , sound absorption , decorative materials , such as foam and activity room , 10% ; insulation materials used in transportation , 10% ; others (7.5%) , of which the furniture , clothing, greater consumption of bicycles .Masking tape


Also the development of China's automobile industry and motorcycle industry also molded soft PUR foam provides a broad market .

Polyurethane foam is the most important of polyurethane products , wide range of uses , excellent performance : Soft PuR PUR foam and semi-rigid foam liner is mainly used for furniture and decoration materials , car mat material , carpet underlay , clothing lining building sound-absorbing materials, sports mat material , as well as mattresses and instrumentation packaging materials and other aspects . The main purpose molded flexible polyurethane foam car seat cushion material and motorcycle , bicycle seat , etc. ; rather rigid polyurethane foam is mainly used in refrigerators, cold storage industry for insulation materials , accounting for rigid foam 57.5% of the total consumption.

Experts predict that due to the plasticity of polyurethane excellent material properties and practical applications in automobiles are increasingly expanding , is a rare building materials.Washi tape


I believe that with the advancement of technology and the development of the construction industry , polyurethane foam materials will be effective in reducing the cost of polyurethane foam material will popularize and promote the application of the construction work in the construction industry as workers and managers should in this regard there are certain forward-looking , good preparations beforehand rigid polyurethane foam materials , better construction companies for the development and construction industry efforts.Sellotape
