YANTAI, China - Wanhua Chemical Group announced the successful start-up of the company’s new IPDI plant. Wanhua will be the first Asia-based company 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 and a fully integrated supply chain, the new state-of-the-art plant strategically places Wanhua in this market. 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 opportunities 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 the company has 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 Wanhua Chemical Group’s 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.
