Dimethyl Terephthalate (DMT, CAS 120-61-6) is a high-purity aromatic organic ester and core polyester monomer. Our DMT is made from terephthalic acid through esterification with methanol, then refined, crystallized and dried to yield high-purity DMT. The annual production capacity is 10,000 tons. It appears as white crystalline flakes or white granular solid at room temperature, odorless, stable in normal storage environment.
