Dioctyl Terephthalate, Bis 2-ethylhexyl Terephthalate, DOTP, 6422-86-2

Dioctyl Terephthalate (DOTP) is a non-phthalate plasticizer used in the polymer industry. It is an ester of terephthalic acid and 2-ethylhexanol. DOTP is known for its excellent plasticizing efficiency, good processing performance, superior thermal aging stability, high dielectric properties, high cold resistance, and low volatility.
