Di-(2-ethylhexyl) terephthalate (DEHT/DOTP) is an environmentally friendly plasticizer mainly used for PVC processing. It provides excellent flexibility, durability, and low-temperature resistance. Commonly applied in the production of flexible PVC products such as cables, wires, flooring materials, synthetic leather, films, hoses, medical tubing, and food-contact packaging materials. It is also used as a replacement for traditional phthalate plasticizers due to its low volatility and favorable safety profile.
