In recent years, the production and quality of rubber sealing products in our country has entered a new stage and new stage. However, only these can not satisfy the need of the development of other industries of various types of rubber seal products standardization and serialization of products, especially compared with the international advanced countries, our products in terms of product quality, or product varieties, has a considerable gap. The 100 forum focuses on the concept, seal the research content and research significance, summarizes the current situation of rubber seal, mechanical seal and packing seal technology, analysis of Chinas and the world advanced sealing technology in developed countries at the level of research and development ability of the new products on the gap, and our future focus on the seal the field of research and put forward some suggestions.
　　The overall competitiveness of Chinas sealing industry is not strong
　　As we all know, in our country, the sealing industry can be said to be the smallest of the industry, but the product can be used with the big industry. Whether in aviation, marine, petroleum, chemical industry, machinery, power generation, metallurgy, mining, etc., can not be separated from the seal. In short, all organic, pump, pipe, valve place, are dependent on the seal. So the industry is small, the surface is very wide.
　　In recent years, with the development of the economy, the development of the sealing industry is also very fast. But unlike other industries, the development of the seal industry is fast, but the change is slow. For example, at the end of 70s and early 80s, there are several manufacturers only in Jiangsu, Zhejiang and Shandong, and both coastal and inland, and the South and the north, everywhere seal factory, the entire industry has been sealed by the previous few, the development of 300, the growth rate can be said to be very fast. But in terms of individual enterprises, many enterprises did not change, the scale of production roundabout, or even reverse, the power of science and technology not only did not increase greatly, but some in the weakened, many manufacturers still hold "four old" do not put, that old products, old technology, old equipment, old size. Of course, there are some enterprises, some products imitation imitation ability is strong, but in the entire industry have the independent development ability of enterprises is not new.
　　The product is concerned, the vast majority of manufacturers or some spiral wound gasket, packing ring, packing and gaskets and other old products with high strength. A new PTFE products, the technical quality and greatly lags behind other countries, such as PTFE packing, PTFE expansion belt. Looking around, a few new products.
