Mitsui Chemicals Inc. announced that affiliate Kumho Mitsui Chemicals Inc., Seoul, South Korea, commenced operations in late September at additional production facilities for methylene diphenyl diisocyanate (MDI). Demand for MDI is projected to grow at an annual rate of 6% going forward, due in part to policy measures around the globe to improve residential insulation as a means of global warming suppression, as well as due to the heightened demand accompanying economic growth.

Kumho Mitsui Chemicals manufactures and sells high-performance monomeric MDI and modified MDI used for making auto parts, elastic fibers, and synthetic leather, as well as commodity polymeric MDI used for making insulation materials. The newly implemented capacity increase is intended to accommodate increased demand growth for high-performance MDI – employed primarily in electric vehicles for the purposes of noise, vibration, and harshness (NVH) mitigation – as well as the existing demand growth for insulation materials.

In addition to expanding its production facilities, Kumho Mitsui Chemicals will install recycling facilities that can reuse the by-products created during the manufacturing process as raw materials. This will not only aid in significant cost rationalization by improving self-sufficiency for raw materials but will also reduce wastewater emissions from the plant and greenhouse gas emissions from the overall supply chain.

Kumho Mitsui Chemicals is aiming to become a global leader for MDI. With the capacity increase provided by these cutting-edge new facilities, Mitsui Chemicals will pursue both the expansion of its MDI business – which is projected for continued growth moving forward – and further improvements to the performance of its MDI products.
