Introduction of Polyurethane
Polyurethane synthetic material is one of the materials with the fastest growing speed in recent decades. Its industrialized production is carried out mainly through the reaction between organic polyisocyanate and polyols. Polyurethane products with different performances and manifestations can be achieved by selecting different numbers and types of functional groups, and adopting different synthesizing technologies, from very soft foam to extremely rigid foam, from highly wearproof elastomer, painting and coating with high glossiness, to highly elastic synthetic fibers, highly anti-bending synthetic leather, highly cohesive adhesive, and so on. Thus, a new-type synthetic material series with great varieties and excellent performance is gradually formed. With the continuous expansion of production application, this kind of polymer has become an essential material for applications from aviation aircraft to industrial and agricultural production, from recreation and sports facilities to daily necessities such as clothing, food, shelter, traveling etc. Currently, the adoption of polyurethane materials is very popular among developed countries in Europe and the U.S. The consumption of polyurethane in China is also increasing rapidly. With its excellent performance and environmental protection and safety features, polyurethane is playing a more and more important role in such areas as building, vehicle, aviation, medical treatment etc.
Environmental Protection and Safety
Of the existing buildings with over 40 billion square meters in China, 95% are high energy consumption buildings, and only 10-15% of newly constructed buildings can reach the compulsory energy saving standard specified by the State. High energy consumption of buildings has imposed a heavy burden of energy on the State, which restrains the sustainable development of our country. In this context, Haohai has developed new types of polyurethane energy-saving material for buildings according to the State's energy-saving policy and market demand, which include OCF that improves the sealing effect of building's doors and windows, and pre-insulated duct panel that improves the insulation effect of central air-conditioners. The R&D and production of these two major products can not only boost the environmental protection and energy-saving performance of buildings, but also give a broad space for the popularization and promotion of new-type building materials.
As tested by the State Quality Inspection and Testing Center and approved by experts from China Building Circulation Association, Haohai products are safe, hazard-free environmental protection building materials with guaranteed quality in China, and are recommended to nationwide building and construction units, decoration units, building material wholesale markets, and governmental procurement units.
Haohai is committed to providing customers with high-quality, environmental protection, energy-saving and hazard-free products, none of which will cause any harm to human body or the environment during normal usage.
