Rigid polyurethane foam is mainly applied in such fields as refrigerator and freezer, automobile, water heater, and heat preservation of building. According to the structure of demand for polyurethane in China in 2009, refrigerator and freezer took the largest proportion and accounted for 39.four% of the total consumption of rigid polyurethane foam, even though building heat preservation held merely 4.two% in the USA, nonetheless, developing heat preservation accounted for far more than 50% of the total consumption of rigid polyurethane foam. The difference in consumption structure results from the truth that China, as a big manufacturer of refrigerator and freezer, has a fairly huge demand for rigid polyurethane foam in the field of refrigerator and freezer, but, with few specifications on developing power conservation and therefore low utilization of heat insulators for external walls in the previous, has a comparatively tiny demand for rigid polyurethane foam in the field of building heat preservation.
With China’s rising requirements on building power saving and the exceptional heat insulation and preservation performance of rigid polyurethane foam, there will be fantastic development space for the application of rigid polyurethane foam in creating energy saving field. In addition, the application of rigid polyurethane foam in solar water heater field will also see a fast growth.
The report underlines not only the demand, the demand structure, as well as the future demand development, supply & demand balance, and import & export of rigid polyurethane foam but also the improvement of key producers of rigid polyurethane foam ‘black material’ (polymeric MDI) and ‘white material’ (rigid polyurethane foam combined polyether).
In regard to rigid polyurethane foam ‘black material’ (polymeric MDI) sector, the entire marketplace is dominated by a few manufacturers: besides Yantai Wanhua Polyurethanes Co., Ltd., only seven organizations worldwide including BASF, Bayer, Huntsman, Dow Chemical, and Japan’s NPU are in possession of the core production technologies of MDI. Chinese makers of polymeric MDI cover Yantai Wanhua Polyurethanes Co., Ltd., Bayer Polymers (Shanghai), Shanghai Lianheng Isocyanate Co., Ltd. (a joint venture of BASF in China), etc., wherein, Yantai Wanhua accounts for far more than 60% of the total capacity. There are numerous, over 20 in 2009, manufacturing enterprises in rigid polyurethane foam combined polyether industry, with reasonably scattered capacity distribution and comparatively low enterprise concentration ratio. Nevertheless, along with the capacity expansion of organizations like Nanjing Hongbaoli Co., Ltd., Hebei Yadong Chemical Group Co., Ltd., and Bayer (China), the concentration ratio of ‘white material’ makers will witness an evident rise.
