- 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.
- 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.
- This product can be mixed with DOP at free percentage.
- This product can reduce viscosity and increase preserve life in the application of plasticized paste.
