Development trend of construction grade cellulose ether industry
Cellulose ether has excellent properties such as thickening, water retention, and retardation, and is widely used to improve and optimize the performance of building materials products including pre-mixed mortar (wet mixed mortar and dry-mixed mortar), PVC resin manufacturing, latex paint, putty, tile adhesive, insulation mortar, and flooring materials, in order to meet the requirements of energy
The field of building materials is the main demand area for cellulose ethers. Cellulose ethers have excellent properties such as thickening, water retention, and retardation, and are therefore widely used to improve and optimize the performance of building materials products including pre-mixed mortar (including wet-mixed mortar and dry-mixed mortar), PVC resin manufacturing, latex paint, putty, tile adhesive, insulation mortar, flooring materials, etc., making them compliant with energy conservation, environmental protection and other requirements, improving construction efficiency for building and decoration, and indirectly applied to the construction of various types of construction projects such as masonry and plastering, and interior and exterior wall decoration. Due to the large investment scale and various types of construction projects in the field of construction engineering, scattered and different construction progress, building-level cellulose ethers have the characteristics of wide range of use, large market demand, and scattered customer base.
In the middle-to-high-end grade of building-grade HPMC, building-grade HPMC with a gel temperature of 75°C is mainly used in the field of dry-mixed mortar, etc. It has strong resistance to high temperature and good application effect. Its application performance cannot be replaced by building-grade HPMC with a gel temperature of 60°C. High-end customers have higher requirements for the quality stability of this type of product. At the same time, there is a certain technical difficulty in producing HPMC with a gel temperature of 75°C. The investment scale of production equipment is relatively large, the threshold for entry is high, and the selling price of the product is significantly higher than that of building-grade HPMC with a gel temperature of 60°C.
"High-end models of PVC-specific HPMC are important additives for PVC production. Although the amount of HPMC added is small and its proportion of production cost is low, the product has good application effects, so its quality requirements are high. There are few manufacturers of PVC-specific HPMC domestically and abroad, and the price of imported products is much higher than that of domestic products."
Development trend of building materials-grade cellulose ether industry
The construction industry in our country is steadily developing, which continues to drive the market demand for building materials-grade cellulose ethers
According to data released by the National Bureau of Statistics, in 2021, China's urbanization rate (the proportion of urban population to the total population) reached 64.72%, an increase of 0.83 percentage points compared to the end of 2020, and an increase of 14.77 percentage points compared to the 49.95% urbanization rate level in 2010, indicating that China has entered the mid-to-late stage of urbanization development. Correspondingly, the growth of the total demand for the domestic real estate market has also entered a relatively stable stage, and the differentiation of demand in different cities has become increasingly apparent. For example, small and medium-sized cities experiencing population outflow demand improvement for mid-to-large-sized housing, and the housing demand of new urban residents in large cities with large population inflows continues to increase. In the future, with the decline of the share of manufacturing and the increase of the share of the service industry in China, as well as the increase in flexible employment forms such as innovation and entrepreneurship, and the development of flexible office models, new requirements will be put forward for urban commercial, residential spaces, and the balance between work and living. There will be more diversified demands for real estate products, and the domestic real estate industry and construction industry will enter a transitional and transformative period.
