Plasticizer
DOTP (Dioctyl Terephthalate) is a non-phthalate, environmentally friendly plasticizer widely used as a replacement for o-phenyl plasticizers such as Dioctyl Phthalate (DOP). Due to its safety and environmental characteristics, DOTP is widely used in several industries, especially in the production of plastic products such as PVC.

Used in plastic, rubber, emulsifier, etc.
The solubility in water is 0.4% when 20℃, soluble in most of the organic solvents and hydrocarbon. Partly compatible with acetate, polyvinyl acetate.
DOTP exhibits good heat and UV resistance, making it particularly suitable for applications that require prolonged exposure to high temperatures or outdoor environments, such as wire and cable and outdoor construction materials.
At high temperatures, DOTP has low volatility, making it suitable for use in applications requiring long term stability and reducing plasticizer loss during use.
DOTP is compatible with a wide range of polymer materials, and can be perfectly combined with PVC and other materials to enhance the flexibility and processability of the product.
DOTP has good electrical insulation properties and is widely used in cable insulation and wire manufacturing.
