Yantai, China -- Wanhua Chemical is taking steps to significantly expand the global footprint of its aliphatic isocyanate business by, among other activity, debottlenecking the existing manufacturing facilities.
The company also plans to convert a unit earmarked for H12MDI production to the production of HDI monomer and the addition of a new 5,000 mT/a HDI biuret plant, scheduled to begin production at the start of 2015.
By the end of 2015, the annual capacity of HDI monomer, HDI trimer, HDI biuret and IPDI will reach 30,000mT/year, 20,000 mT/ year, 5,000 mT/year and 15,000mT/year respectively, the company said in a press release.
By 2017 Wanhua Chemical will also invest in additional production lines for both HDI monomer and HDI trimer, leading capacities of 70,000mT/year for HDI monomer; 50,000mT/year for HDI trimer: 5,000mt/year for HDI biuret; 10,000mT/year for H12MDI and 15,000mT/year for IPDI.
Currently, Wanhua Chemical's manufacturing capacity for HDI monomer, HDI trimer and H12MDI is 15,000mT/year, 15,000mT/year and 3,000mT/year respectively, the press release said.
Currently, HMDI is produced in the Wanhua site in Ningbo. HDI series products are produced in both Wanhua Yantai and Ningbo sites. From 2017, both HMDI & IPDI facilities will be located in Yantai industrial park.
The company said that for HMDI and IPDI, it possesses the whole industrial chain backward integrated from aniline and acetone respectively. For HDI and derivatives, Wanhua has global purchasing agreements in place.
According to Wanhua, the average growth rate for the coatings industry in China is approximately 8% . It also estimates the ADI products rate growth rate to be consistent with coatings' growth rate.
