TOKYO—Mitsui Chemicals plans to launch Fortimo and Stabio, two new aliphatic polyurethanes, in April.
Fortimo is based on 1.4-bis (isocynatomethyl) cyclohexane (1.4-H6 XDI) and a polyurethane elastomer material. This combination offers elasticity, durability, and superior heat resistance to other isocyanates, Mitsui said. The product is non-yellowing and has a short molding time, the firm added.
The Stabio grade is based on 1.5 pentamethylene diisocyanate (PDI), said Mitsui. The firm says the PDI material has high reactivity compared to hexamethylene diisocyanate, has improved gloss, chemical and abrasion resistance is non-yellowing and is made with 70 percent biomass.
Production will start at existing facilities, the firm said. Mitsui said that production plans to start preparing for large-scale isocyanate production at Omuta, Japan, and as a new facility for derivatives at Nagoya, Japan. Mitisui added that it is planning for phased plant expansions in the future.
Mitusi said that these new materials are part of its strategy to produce specialty isocyanates including m-xylene diisocyanate (XDI), norbornane diiocyante (NBDI) and their derivatives.
