Dimethyl  terephthalate is the main monomer of PET and PBT polymers. SASA makes its own DMT production. SASA  has the biggest  established DMT  capacity in the world.  The production capacity is 750 tpd. The majority of the  production is used in house with the residual capacity sold  in solid forms.

The main end use of DMT is polyester production. DMT is shipped  as briquette in big bags.
