Global DMT Production Capacity
Global demand for DMT is estimated to increase by an average of 0.7% during the period 2003-08. DMT has lost its ground and will continue to lose significant market share to terephthalic acid (PTA) in PET melt manufacturing. Small capacity debottlenecking will occur in a few countries such as Korea. Mexico, Germany, and Korea are the leading DMT export countries.
DMT competes for use with terephthalic acid (PTA) as a feedstock for polyethylene terephthalate (PET) production. On a new plant basis, it is usually more economical to produce PET from PTA rather than from DMT. Most capacity additions are planned for PTA. In 1998, PTA accounted for 86% of total global PET melt; in 2002, it was 90%. From 1998 through 2002, worldwide DMT capacity decreased by approximately 724,000 metric tons, or 14%. PET melt made from recycle PET solid-state bottles and used to produce polyester fibres has also decreased DMT demand.
