Dioctyl terephthalate (DOTP), the transparent oily liquid, is insoluble in water, but easily soluble in general organic solvents. It is an organic compound with the molecular formula C24H38O4. DOTP is an excellent main plasticizer for polyvinyl chloride (PVC) plastics. Compared with the commonly used dioctyl phthalate (DOP), DOTP has the advantages of heat resistance, cold resistance, hard to volatilize, resistance to extraction, flexibility and electrical insulation properties, so DOTP shows excellent durability in products Performance, soap resistance and low temperature flexibility.
