The integration of domestic silicone building sealant is paying off

As an important part of silicone polymer materials, silicone building sealant (commonly known as silicone rubber) at room temperature without heat, light or other conditions can be cured variable elastic rubber, very convenient to use, except with general silicone materials of high and low temperature resistance, cavitation when aging, high electric insulation and other excellent properties, also has good cohesiveness of of all kinds of material, anti deformation ability is strong and so on characteristics has become modern building decoration important sealing material.
Foreign silicone rubber after decades of development, in terms of raw materials and a dedicated production equipment supporting are very good, the major producers of concentrated in several of the world's largest silicones, most of the manufacturers have an annual output of more than million tons. From the point of view of consumption and foreign silicone sealant price to be higher than other products, accounting for about one third of the sealant usage, but there has been a tendency to gradually replace the other sealant.
The contrasts with the situation for domestic, in addition to greater acrylic sealant price is relatively low, usage, poly sulfur and silicone prices close to, price of polyurethane adhesive is higher than silicone, makes silicone sealant to occupy the market share of over 70%. In the last five years, the silicone rubber enterprises mainly in the realization of the continuous production process of silicone rubber were a large number of technological transformation, greatly improves the production efficiency, effectively reducing the normal loss and energy consumption, at present, more than 60% of the domestic brands have adopted the advanced continuous production process. In October 2013, Jiangxi spark organosilicon plant will France BSI company patent was successfully transferred to a new organic silicon production line; in March 2014, Guangzhou Baiyun Chemical Industry Co., Ltd. to horse production 8 00000 tons of high performance copper silicon sealant continuous production base.
At present, the entire industry, the production scale and management level is uneven. Just the end of the aluminum door and window curtain wall industry annual meeting, China Construction Metal Structure Association Yao Bing president and aluminum door and window curtain wall Committee Huang Qi director said, in 2013, Guangzhou Baiyun, Hangzhou Zhijiang, the Central Plains, Zhengzhou, Chengdu Guibao, Yongan plastic industry etc. five domestic silicone rubber leading enterprises of production and sales did not decrease, but increased slightly; and poor operation of small enterprise value showed a significant downward trend, the future market share will gradually being dominated by big brands.
