my country is highly dependent on imports of chloroprene latex, with the construction waterproofing field being its main demand end.

Chloroprene latex is a kind of synthetic latex, which refers to a high molecular polymer made of chloroprene as the main raw material and polymerized in emulsion. Chloroprene latex appears as a milky white or white fluid liquid. It has the advantages of good film-forming properties, strong adhesion, superior impermeability, and resistance to acid and alkali corrosion. It is widely used in building waterproofing, sponge products, coatings, sealing materials, and modified cement. , papermaking and other fields are widely used. Butadiene method and acetylene method are the main preparation methods of chloroprene latex.

​​ ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ away from my country. According to statistics from the General Administration of Customs of China, my country’s imports of chloroprene latex will reach 4,000 tons in 2022, a year-on-year increase of nearly 13%. Japan and Germany are my country’s main importers of chloroprene latex, and the above two countries account for nearly 95% of my country’s total import volume. In terms of the export market, due to factors such as the epidemic, overseas chloroprene latex companies have suspended operations and production, which has led to an increase in my country’s chloroprene latex exports. India and Kuwait are my country’s main exporters of neoprene latex.

​ ​ ​Chloroprene latex is mainly used in construction waterproofing, coatings, modified cement and other fields. The field of construction waterproofing is the largest demand end for chloroprene latex, which can be used for basement waterproofing, sky waterproofing, high-rise building exterior wall waterproofing, etc. However, currently, due to factors such as high production costs, my country’s chloroprene latex market share is low and the industry is developing slowly. According to the “2023-2028 China Neoprene Latex Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, In 2022, my country’s chloroprene latex production capacity will reach 19,000 tons, and the output will reach 7,000 tons.

Chloroprene latex is usually divided into two categories: positive latex and negative latex. Positive latex, also known as cationic chloroprene latex, has the properties of chloroprene rubber and is widely used in the field of waterproofing. It is a mainstream product in the chloroprene latex market. Negative latex is also called anionic chloroprene latex. Its production process is relatively complex, but it has the advantages of long service life and convenient use, and improves the shortcomings of traditional chloroprene latex such as poor aging resistance. With the growth of market demand for segmented products, the development speed of the chloroprene latex industry will accelerate in the future.

The global chloroprene latex market is mainly concentrated in Europe, the United States, Japan and other countries. Leading companies include Japan’s Tosoh Corporation (TOSOH), Japan’s Denka Chemical Industry Corporation (Denka), Germany’s Covestro (Covestro), etc. There are few chloroprene latex manufacturers in my country, including Shanxi Huozhang Chemical Synthetic Rubber Co., Ltd., Shanna Synthetic Rubber Co., Ltd., etc.

          Industry analysts said that as a synthetic latex subdivided product, chloroprene latex has excellent performance and is in strong demand in the field of building waterproofing. However, currently, due to factors such as high production costs, my country’s chloroprene latex market penetration rate is low and the industry is developing slowly. In the future, with the improvement of technological maturity, the high production cost of chloroprene latex in my country is expected to be reduced. By then, its production capacity will be expanded and output will increase.
