As a fiber sub-nano material calcium sulfate whisker industry development trend is better

Calcium sulfate whiskers, also known as gypsum whiskers and gypsum fibers, are a new type of fiber sub-nanomaterials. According to the different water content, calcium sulfate whiskers are mainly divided into anhydrous calcium sulfate whiskers, hemihydrate calcium sulfate whiskers, dihydrate calcium sulfate whiskers three.

According to the "In-depth Market Research and Investment Strategy Recommendations Report on Calcium Sulfate Whisker Industry 2022-2027" released by the New Sijie Industry Research Center, natural gypsum is the main raw material for calcium sulfate whiskers. China is rich in mineral resources, natural gypsum concentrated in Shandong, Qinghai, Inner Mongolia, Jilin, Hunan, Jiangsu and other places. Shandong has the largest number of gypsum mines, accounting for 65.0 percent of the total reserves of natural gypsum resources in China. Benefiting from the superior geographical environment, China's natural gypsum production continues to grow, exceeding 0.23 billion tons in 2021, ranking first in the world. The supply and demand of raw materials market is stable, driving the production of calcium sulfate whiskers in China.

Calcium sulfate whiskers are mainly used in rubber products, plastic products, coatings, paper industry, friction materials, medical and health, building materials and other fields. In the paper industry, calcium sulfate whiskers, as the main raw material, can fully replace natural plant fibers. Calcium sulfate whisker is a typical short fiber, which has the advantages of high whiteness, strong adsorption, non-toxic and environmental protection, high retention rate, and can effectively improve the strength and ash content of paper. According to statistics from the China Paper Association, my country's paper and paperboard output reached 121.05 million tons in 2021, an increase of 7.5 percent over the previous year. Driven by market demand, the scale of China's calcium sulfate whisker industry will be further expanded.

Modified anhydrous calcium sulfate whiskers are subdivided products of calcium sulfate whiskers prepared by surface modification. Compared with calcium sulfate dihydrate whiskers and calcium sulfate hemihydrate whiskers, modified anhydrous calcium sulfate whiskers have stronger adsorption and compatibility, and have a wider range of applications. In the local market, China's modified anhydrous calcium sulfate whiskers are mainly used in the production of rubber products and plastic products, with demand accounting for up to 70.0 percent. In recent years, China's modified anhydrous calcium sulfate whisker production has been increasing, in 2021 has exceeded 22000 tons.

China's calcium sulfate whisker industry started late, but there are many manufacturers, including Ningyuan Longxiang new materials, Sichuan Wanrun Industrial, Sichuan Kangsheng whisker, Jiangxi Fengzhu new materials, Changzhou Guangwei new materials. Due to high technical barriers and national environmental protection policy restrictions, China's calcium sulfate whisker market is mainly small and medium-sized enterprises, the main products are concentrated in the low-end areas, high-performance calcium sulfate whisker products are highly dependent on imports.

New Sijie industry analysts said that calcium sulfate whiskers, as a new type of fibrous sub-nanomaterials, have been widely used in many fields with their excellent properties. Driven by the downstream industry, China's calcium sulfate whisker market continues to expand. Affected by positive factors such as continuous innovation of production technology and national policy support, the application scenario of calcium sulfate whisker in China will be further expanded, and the development trend of the industry will continue to improve.
