MDI is a key raw material for polyurethane, a signature material used in numerous fields such as auto parts, seating for cars and furniture, insulation foam for homes and fridges, elastic fibers, various adhesives. Demand for MDI is projected to grow at an annual rate of 6 percent going forward on account of 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 used for making elastic fibers and synthetic leather, as well as commodity polymeric MDI used for making insulation materials. The upcoming capacity increase is intended to accommodate an expanded growth in demand for high-performance MDI – employed primarily in electric vehicles for the purposes of noise, vibration and harshness (NVH) mitigation, as well as the growing demand 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 improve self-sufficiency for raw materials, and 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. Mitsui Chemicals will pursue expansion of the MDI business, which is projected for continued growth moving forward, and improving the performance of MDI products.
