Plasticizer DOTP 99.5% Dioctyl terephthalate (DOTP) CAS 6422-86-2

Short Description:

Chemical name: Dioctyl terephthalate
Other name: DOTP, Bis(2-ethylhexyl)terephthalat
CAS #: 6422-86-2
Purity: 99.5% min
Molecular formula: C24H38O4
Molecular weight: 390.56
Chemical Properties: Colorless or slightly yellowish oily liquid. Almost insoluble in water, solubility of 0.4% in water at 20℃. Soluble in common organic solvents
Application: Dioctyl terephthalate (DOTP) is an excellent primary plasticizer for polyvinyl chloride (PVC) plastics. Compared with the commonly used diisooctyl phthalate (DOP), it has the advantages of heat resistance, cold resistance, non-volatile, anti-extraction, softness and electrical insulation properties, and shows excellent durability in products, Soapy water resistance and low temperature softness.

1. DOTP is a sort of high-performance primary plasticizer with good electrothermal properties. Its volume resistivity is ten-twenty times of DOP’s. Good plasticating effect and low volatility on cable materials makes it be widely used on the heat-resisting, high
insulation product. It is the ideal plasticizer for the production of 70 degrees C. cable material and other volatility-resist PVC products.
2. Meanwhile it has favourable cold-resistance, heat-resistance, extraction-resistance performace, with low volatility and high plasticizing efficiency. In its downstream products, good durability, soap water resistance and softness in low temp. was been
found. It is suitable for the plasticizer of PVC resins, such as high-insulation PVC cables.
3. This product can be mixed with DOP at free percentage.
4.This product can reduce viscosity and increase preserve life in the application of plasticized paste.
Application Guide: Widely used in cable materials, insulating wires, high-grade paint, coating, PVC gloves, artificial leather, etc.
