在日本软质聚氨酯泡沫所用国产原料的自给已有十多年了,而日本的聚氨酯工业还处于很年轻的时代,自进入七十年代以来,正在获得急速的发展。在世界上聚氨酯也是引人注目地显著地增长,其地位可以与二十年代的钢铁,四十年代的聚烯烃之先例相匹敌,在美国予计其消费量到1975年达100万吨,到1980年达200万吨。作为国内需要主要的软质和硬质泡沫体制品在稳步地增长,而弹性体、涂料等非泡沫体领域用途的开发也很兴旺。从寝具、家具、衣料、合成皮革等日常生活用品到汽车部件,船舶、建筑、工厂设备等用作绝热之类的工业材料,基于聚氨酯具有以下列举的特征进而期望达到光辉 The self-sufficiency of domestic raw materials used in Japan’s flexible polyurethane foams has been more than a decade, and Japan’s polyurethane industry is still in a very young age. Since entering the 1970s, it is gaining rapid development. In the world, polyurethanes have also noticeably and significantly increased. Their status can match that of the steel industry in the 1920s and the precedent of polyolefins in the 1940s. In the United States, it is estimated that the consumption will reach 1 million tons by 1975. In 1980 it reached 2 million tons. The domestic demand for soft and rigid foam products is steadily growing, and the use of non-foam fields such as elastomers and coatings is also booming. From household items such as bedding, furniture, clothing, and synthetic leather to automotive parts, ships, buildings, and factory equipment are used as industrial materials such as thermal insulation, and polyurethanes have the following characteristics and are expected to achieve brilliance.
