The production process includes direct esterification and transesterification.
Main performance:
1. DOTP is a main plasticizer with excellent performance. It has excellent electrical and thermal properties. Its volume resistivity is 10 to 20 times that of DOP. It has good speed-increasing effect and low volatility on cable materials It is widely used in various products requiring heat resistance and high insulation. It is an ideal plasticizer for the production of cable materials with a temperature resistance of 70 degrees Celsius and other volatile PVC products.
2. At the same time, it has good cold resistance, heat resistance, extraction resistance, volatility resistance, and a higher rate of growth. It shows excellent durability, soap water resistance and low temperature flexibility in products. It is suitable as a plasticizer for PVC resin, such as PVC cable materials that require high insulation.
3. This product can be blended with DOP in any proportion.
4. This product can reduce viscosity and increase shelf life when used in plasticizing paste.
Application Guide:
Widely used in cable materials, insulation skins, high-grade paints, coatings, etc.
