The aliphatic isocyanate (ADI) industry has high entry barriers and Wanhua Chemical is a leading domestic company

Aliphatic isocyanate (ADI) refers to isocyanate products other than aromatic. ADI molecules have -N=C=O functional groups. Polyurethane materials prepared with ADI have good anti-aging, high temperature resistance, yellowing resistance, light resistance and other properties. Downstream applications involve aerospace and military industry, high-end equipment, rail transit, automobiles, etc. Artificial leather, coatings and other fields.

There are many types of ADI, including isophorone diisocyanate (IPDI), hexamethylene diisocyanate (HDI), 4′-diisocyanate (HMDI), methylcyclohexane diisocyanate (HTDI), trimethylhexane diisocyanate Methyl diisocyanate (TMDI), xylylene diisocyanate (XDI), etc. Among them, HDI, IPDI, and HMDI have higher output. Among the three, HDI has the highest output, accounting for about 65% of ADI output.

There are many types of ADI and a wide range of downstream applications. In recent years, with the development of high-end equipment, automobiles, aerospace and other industries, the global ADI market demand has continued to grow. At present, Europe, the United States, China and Japan are the main consumer countries and regions of ADI globally. In recent years, my country’s industry has developed rapidly, and my country has become the main driving force for global ADI market demand, with a growth rate higher than the global average.

According to the “2021-2025 ADI Industry In-depth Market Research and Investment Strategy Suggestions Report released by the Industrial Research Center, at this stage, The total production capacity of the global ADI industry reaches 580,000 tons/year. Due to the high barriers to entry in the industry, there are few companies in the world that can produce ADI on a large scale, mainly including Covestro, Evonik of Germany, BASF of Germany, Asahi Kasei of Japan, Wanhua Chemical, France Rhodia and other companies, among which Covestro is the world’s largest ADI supplier with an annual production capacity of 220,000 tons, followed by Wanhua Chemical, with an annual production capacity of about 140,000 tons.

The ADI production process is long and contains a variety of complex processes and chemical reactions, such as organic synthesis, phosgenation reactions, etc. Therefore, the ADI industry has high production, technology, and environmental protection barriers. Due to this restriction, most of the global ADI production capacity is currently concentrated in overseas markets. my country’s ADI production capacity is relatively small. Wanhua Chemical is the leader in the domestic ADI industry.

Wanhua Chemical is the only local large-scale manufacturer of ADI. Currently, the company has achieved industrialized production of HDI, IPDI, and HMDI products. With the commissioning of Wanhua Ningbo’s 50,000 tons/year HDI device, Wanhua Chemical’s ADI production capacity will be further increased. . Wanhua Chemical is also one of the few companies in the world that masters the three ADI monomers of HDI and derivatives, IPDI, and HMDI. In recent years, while expanding ADI production capacity, Wanhua Chemical has also actively explored the entire specialty amine-ADI-PUD industry chain. , MDA-H12MDA-H12MDI full industry chain, IP-IPN-IPDA-IPDI full industry chain layout, and promote the integrated development of the ADI industry.

Industry analysts said that there are many types of ADI and a wide range of downstream applications. In recent years, with the development of my country’s economy, the demand for ADI market has increased. Faster. At present, ADI production capacity is mostly concentrated in overseas markets. After continuous development and accumulation, my country’s ADI production capacity has improved. Wanhua Chemical is the main supplier. Due to high production technology requirements, it is difficult for new ADI to enter. In the future, Wanhua Chemical will remain The main force in the development of ADI industry.
