Polyurethane: build the world's largest raw material and product base

Polyurethane is an important new chemical material.
Because of its excellent performance and versatile use, it is known as the "fifth largest plastic"
.

China's polyurethane industry has gradually developed and grown with the 100-year history of the founding of the party

After the reform and opening up, China began to introduce foreign advanced TDI production technology and equipment
.

In 1983, the 10,000 tons of methylene diphenyl diisocyanate (MDI) and TDI project built by the former Ministry of Light Industry in Yantai, Shandong Province was put into production

After the 1980s, China began to introduce foreign advanced polyurethane raw materials and product production technology and equipment.

Domestic scientific research institutions and enterprises also began to develop reaction injection molding, high resilience cold-cured foam, polymer polyols, modified MDI, etc.

After the 1990s, with the sustained and rapid development of China's economy, polyurethane, as a new multifunctional polymer material, has been widely used in transportation, home appliances, furniture, metallurgy and other fields
.

The rapid growth of demand has also further stimulated the development of the polyurethane industry.

In the 21st century, after more than ten years of research and experience accumulation, through the digestion and absorption of imported technology and equipment, China has basically mastered the production technology of polyurethane's main raw materials
.

With the rapid development of China's refrigerator, freezer, and furniture industries, and the rapid rise of the application of polyurethane materials, China's polyurethane industry has entered a stage of rapid development and has become one of the fastest growing fields in China's chemical industry

During the "Thirteenth Five-Year Plan" period, the polyurethane raw material industry has been digested, absorbed and recreated for nearly 20 years.
MDI production technology and production capacity are at the world's leading level.
Polyether polyol production technology and scientific research and innovation capabilities continue to improve, and high-end products continue to emerge , The gap with the advanced level of foreign countries is constantly narrowing
.

In 2019, China's polyurethane product consumption is about 11.

　　At present, the production capacity of major polyurethane raw materials in China has exceeded 1/3 of the global production capacity.
It has become the world's largest production base of polyurethane raw materials and products, and the region with the most comprehensive polyurethane application fields in the world.
The production and consumption of raw materials and products in the industry continue to grow.
The structure continues to be optimized
.

The output value of China's polyurethane raw materials is 60 billion yuan, and the output value of products is 320 billion yuan.

　　At present, the polyurethane industry has entered a new stage with the theme of innovation and green development
.

At present, the output of polyurethane downstream products such as building materials, spandex, synthetic leather and automobiles ranks first in the world
.
The country is vigorously promoting water-based coatings, implementing new policies for building energy conservation, and developing new energy vehicles, which also bring huge market opportunities to the polyurethane industry
.
The "dual-carbon" goal proposed by China will promote the rapid development of building energy saving and clean energy industries, and bring new development opportunities for polyurethane insulation materials, coatings, composite materials, adhesives, and elastomers
.

　　In April this year, China announced its acceptance of the "Montreal Protocol" Kigali Amendment to strengthen the control of non-carbon dioxide greenhouse gases such as hydrofluorocarbons (HFCs)
.
China is the world's largest producer and user of HFCs.
Among them, HFCs blowing agents are widely used in the polyurethane foam industry, and there are challenges in reducing work
.
At present, Buyian New Materials, Shaoxing Huachuang, Jiangsu Meside and other companies have increased the research and development of new foaming agents and matching foam stabilizers, catalysts and other auxiliaries for the task of replacing ODS as a foaming agent in the polyurethane industry.
, To contribute to the improvement of the atmospheric environment
