At present, the MDI production capacity of more than 1 million tons per year is under construction.
In addition to the expansion of Wanhua and Covestro, Xinjiang Heshan Juli Chemical Co.
, Ltd.
has invested in new construction, and BASF has also joined hands with INOV to increase production
.

Wanhua Chemical

The Wanhua Chemical (Fujian) MDI Industrial Park project is located in Jiangyin Gangcheng Economic Zone, Fuqing.
The first phase is planned to invest in 4 new projects, including the MDI project with an annual output of 400,000 tons, which has officially started in March 2020
.

The annual production MDI project of Xinjiang Heshan Juli Chemical Co.
, Ltd.
is located in Kuidong Characteristic Industrial Park, Kuitun-Dushanzi Economic and Technological Development Zone, within the existing factory of Xinjiang Heshan Juli Chemical Co.
,
Ltd.
The total investment of the project is 4,664.
24 million yuan.
The main construction content and scale is a 400,000-ton/year MDI project production unit.
The MDI synthesis method adopts the phosgenation method
.
In January 2020, the project will be announced before approval
.

BASF

On the morning of April 15, 2020, Shandong Yinuowei Polyurethane Co.
, Ltd.
and BASF signed a strategic cooperation agreement.

.

Covestro

In November 2018, the environmental impact assessment of Covestro Polymers (China) Co.
, Ltd.
's MDI expansion from 500,000 tons/year to 600,000 tons/year was released.
The company's MDI production capacity in Shanghai Chemical Industrial Park will increase from 500,000 tons/year.
Expand production to 600,000 tons/year
.

This project is a reconstruction and expansion based on the existing equipment.
Most of the production equipment and environmental protection facilities rely on the existing equipment to achieve the purpose of expanding the production by 100,000 t/a MDI by extending the operation time and improving the production efficiency per unit time.
Supporting environmental protection improvement measures such as phenol removal, chlorobenzene recovery, and phosgene decomposition system wastewater reuse
