Recently, by the zibo ZhengHua foaming materials co., LTD and shandong university of science and technology joint research and development of green environmental protection polyurethane chemical foaming agent CFA - A8 through identification of scientific and technological achievements in Beijing, reached the international advanced level. This is the first time by Chinese scientists chemical synthesis of a water-soluble non-aqueous chemical foaming agent completely. The product is expected to replace CFCS existing physical foaming agent in the world. According to understand, polyurethane is a new kind of organic polymer materials, is known as \"the fifth big plastic\". Polyurethane rigid foam foaming process has been adopting physical foaming agent, which USES mostly freon series such as CFC - 11, serious damage to the atmospheric ozone layer. According to statistics, the dosage of foaming agent of polyurethane hard foam foaming process about 20% of the white material, the hard bubble of production in China is about 1 million tons, the annual growth rate of about 15%. The chlorine fluorine the current usage of the foaming agent is about 100000 tons. The expert thinks, polyurethane chemical foaming agent CFA - A8 do not contain halogen element, the production of reactants, the cost is low, the production process has no \"three wastes\" emissions, clean environmental protection, the successful development of this product will be conducive to accelerate the phase out of existing CFCS physical foaming agent in the world, to our country on time to the Montreal protocol on international conventions, CFCS compounds provided technical support.
