Recently, Wanhua Chemical Group Co., Ltd. (hereinafter referred to as "Wanhua Chemical") isocyanate expansion news constantly. In April, the environmental impact information of the first and second phase of the toluene diisocyanate (TDI) project in Fujian Industrial Park was released one after another; on April 30, it was also announced that the polymer methylene diphenyl diisocyanate (MDI) plant in Fujian Industrial Park has recently completed the technical transformation and expansion capacity from 400000 tons / year to 800000 tons / year, and already has the conditions for trial production. On the basis of the leading core technologies of MDI and TDI, Wanhua Chemical is constantly striving for more market voice through capacity expansion.

Wanhua Chemical is currently the world's largest supplier of MDI and TDI, with a production capacity of 3.5 million tons / year for MDI and 950000 tons / year for TDI. The company has 1.1 million tons / year MDI and 300000 tons / year TDI devices in Yantai, 1.2 million tons / year MDI devices in Ningbo, 400000 tons / year MDI and 250000 tons / year TDI devices in Hungary, 800000 tons / year MDI devices and 250000 tons / year TDI devices in Fujian, and 150000 tons / year TDI devices in Xinjiang.

In 2023, the global market situation of polyurethane and its raw materials is complex, but driven by downstream refrigerator freezers, automobiles, formaldehyde-free plates, spandex and other industries, it has achieved small growth throughout the year. In 2023, Wanhua Chemical ensures the stable operation of the original equipment, does a good job in the start-up operation and sales of the new devices of 400000 tons / year MDI and 250000 tons / year TDI in Wanhua Fujian, deepens the cooperation with strategic customers in downstream traditional industries, continues to cultivate new application fields, and maintains a benign and healthy development trend.

According to the global MDI plant production plan in 2024, there are three expansion projects during the year, with an additional capacity of 700000 tons / year, of which China is Fujian Wanhua 400000 tons / year MDI technical renovation unit, Chongqing BASF 100000 tons / year production expansion plan, overseas for South Korea Jinhu 200000 tons / year production expansion plan. At that time, the production capacity of China's MDI industry will reach 4.88 million tons per year, and the total capacity of the global industry will reach 11.02 million tons. With the completion of the technical transformation of the Fujian MDI plant, the MDI capacity has been expanded from 400000 tons / year to 800000 tons / year. Wanhua Chemical MDI production capacity accounts for 33% of the global total capacity.

As for TDI, Wanhua Chemical is also stepping up its capacity expansion. On April 23rd, Wanhua Chemical released the first Environmental impact report of TDI Phase I Technical Reform and capacity expansion Project of Wanhua Chemical (Fujian) Co., Ltd., and the Environmental impact Assessment report of TDI Phase II expansion Project of Wanhua Chemical (Fujian) Co., Ltd. on April 18th. Wanhua Chemical plans to expand the capacity of the first phase of Fujian TDI project from 250000 tons / year to 360000 tons / year, and the second phase of the project will build a process plant of 360000 tons / year TDI. After the completion of these two expansion projects, Wanhua Chemical TDI capacity will increase by another 470000 tons / year to reach 1.42 million tons / year.

At present, Wanhua Chemical MDI and TDI production technology is the world's leading. In the field of TDI, in addition to Yantai and Hungarian Bosu devices, in the past three years, we have also acquired and integrated Fujian Southeast Electric, Juli and other TDI business. Through technological transformation and equipment investment, the purity of TDI products has reached 99.99%, reaching the world's leading level.

Large-scale benefits will bring more competitive raw material costs and processing cost advantages to Wanhua Chemical. So far, only Wanhua Chemical and Keschuang have a global production capacity of 300000 tons / year for a single set of TDI. Due to the low investment, high operation efficiency and obvious cost advantage of Wanhua chemical single plant, its cost competitiveness is far higher than that of other manufacturers by virtue of the industrial chain advantage of upstream and downstream integration. Other suppliers TDI unit production capacity is mostly 5 to 100000 tons / year, the device is small and scattered, lack of large-scale production efficiency.

According to the analyst's prediction, Wanhua Chemical's future growth path in TDI and polyurethane plate will focus on continuously reducing production costs and continuing to expand market share. With the production capacity of Wanhua Chemical MDI and TDI on the ground, Wanhua MDI and TDI capacity is expected to account for more than 50% of the total global production capacity in the next 3 to 5 years.
