DIOCTYL TEREPHTHALATE (DOTP) is widely used in PVC resins, PVC cables，sheet, flooring materials, artificial leather, gasket, etc. it is known for the similarity to DINP, but no negative regulatory pressure
DIOCTYL TEREPHTHALATE (DOTP) is the ester of terephthalic acid and 2-ethylhexanol. It is a clear, colourless liquid with a slight odour, which is insoluble in water. Dioctyl terephthalate is a very important phthalate-free plasticizer for PVC, preferred over low-chain and ortho-phthalate plasticizers as it is considered a safer alternative due to its low toxicity.
