有机硅按基本形态可分为四大类 :硅油、硅橡胶、硅树脂、硅烷偶联剂。目前 ,世界有机硅年生产能力为１３０万ｔ。我国现有有机硅装置年生产能力约１ ８万ｔ,实际产量为１万ｔ,１９９９年进口有机硅超过３万ｔ。我国有机硅需求正呈大幅度增长态势 ,市场行情十分看好 ,外商已开始 Silicones can be divided into four major categories according to their basic form: silicone oil, silicone rubber, silicone resin, and silane coupling agent. At present, the global organic silicon production capacity is 1.3 million tons. The annual production capacity of organic silicon devices in China is about 180,000 tons, and the actual output is 10,000 tons. In 1999, more than 30,000 tons of organic silicon was imported. The demand for organic silicon in China is showing a substantial growth trend. Market conditions are very promising and foreign investors have begun
