Wanhua Chemical Starts-up IPDI Plant in China
Wanhua Chemical Group, one of the global leaders in the production and sales of Polyurethanes and Petrochemicals, announced the successful startup of their new IPDI plant. Wanhua will be one of the first Asia based companies to employ the complete “IP-IPN-IPDA-IPDI” industry chain technology.

The new plant is located in Wanhua’s 10 square mile Yantai Industrial Park. With the latest phosgene production technology, a fully integrated supply chain as well as superior operation management, the new state of the art plant will put Wanhua in a very competitive situation. Wanhua will market the IPDI monomer under the brand name WANNATE ®.
IPDI is a cycloaliphatic diisocyanate. Due to its primary and secondary isocyanate groups, it allows controlled poly-addition with polyol co-reactants, which provides the possibility to design molecular structures for specific materials. Major applications of IPDI are waterborne polyurethane dispersions, adhesives and UV resins. The IPDI trimer can be used in non-yellowing, high performance PU coatings for various applications such as automotive refinish.
Over the last several years we have been building a very competitive aliphatic diisocyanate product portfolio. After the successful global introduction of HMDI, HDI and their derivatives, the launch of WANNATE ® IPDI will now complete its portfolio and satisfy the global market needs for high performance products. Wanhua will continue to focus on innovation and create even more value for our customers in the future” said Steven Sun, General Manager of Wanhua’s ADI business Unit.
