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.
