Wanhua Chemical Group commissioned new IPDI plant

Wanhua will be the first Asia based company to employ the complete “IP-IPN-IPDA-IPDI” industry chain technology.

Marketed under the brand name “Wannate”

The new plant is located in Wanhua’s ten 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”.

Polyurethane dispersions are major applications

IPDI is a cycloaliphatic diisocyanate. Due to its primary and secondary isocyanate groups, it allows controlled polyaddition with polyol coreactants, 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.

Successful global introduction of HMDI and HDI

“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 our 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.
