Polymer manufacturer
Bayer MaterialSciencehas developed a method for producing toluene diisocyanate (TDI), which reduces production plant construction costs by 10 to 20 percent and energy consumption by one third.
A pilot plant with an annual production capacity of 30,000 tonnes has been in operation in the
Bayer MaterialScience plans to use the new technology for the first time on an industrial scale at its Caojing site near
TDI is used in the production of flexible polyurethane foam, a component of upholstered furniture, mattresses and automotive seating.
In 2005, Bayer MaterialScience finished years of work on a consolidation process for TDI and its primary products and has since focused its production on integrated manufacturing plants.
Bayer MaterialScience has previously developed a similar method for producing methylene diphenyl diisocyanate (MDI), a raw material for producing rigid polyurethane foam used in insulation. The company is currently constructing a world-scale production plant for MDI in Caojing with a capacity of 350,000 tonnes a year, which is due to commence operation in 2008.
The inauguration of a splitter for recovering monomeric and polymeric MDI from crude MDI is already scheduled for autumn 2006. It will boast an annual capacity of 80,000 tonnes.
