Tosoh: New Plant for Emission-free PU Catalyst

The Tosoh Nanyo Complex in Yamaguchi, Japan (figure: Tosoh)

Tosoh Corporation, Tokyo, Japan, has decided to construct a plant to produce Rzeta, the company’s proprietary, new emission-free reactive amine catalyst for polyurethane (PU) foam.

The plant will be built on the grounds of the ethyleneamine production facilities at the Nanyo Complex for an estimated investment of ¥2 billion. Construction of the Rzeta plant will begin in September 2013 and is expected to be completed by November 2014.
PU catalysts are vital for producing PU foams that are used as cushioning for automotive interiors, for bedding, and for furniture and as insulation for refrigerators and construction materials. Those catalysts are also used for the manufacture of shoe soles, adhesives, and paints.

Tosoh developed Rzeta in response to concerns about volatile organic compound (VOC) emissions from PU foams produced using conventional PU catalysts. As an emission-free PU foam reactive amine catalyst, Rzeta enables the manufacture of PU foams that do not emit VOCs or odor characteristic of amine chemicals and are thus better for the environment. The absence of VOCs also means that Rzeta-produced PU foams used in proximity to other resins, such as polyvinyl chloride and polycarbonates, will not change their color. At the same time, Rzeta enables the production of PU foams with the same high level of durability as those made using conventional catalysts.
