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.
