  • Model: dotp

The main properties of relative molecular weight are as follows

The production process includes direct esterification and transesterification.1. DOTP is a kind of main plasticizer with excellent electrical and thermal properties. Its volume resistivity is 10 ~ 20 times higher than DOP. It has good growth effect and low volatility especially in cable materials. It is widely used in various products requiring heat resistance and high insulation. It is an ideal plasticizer for the production of 70 ℃ cable materials and other PVC products requiring volatile resistance.2. At the same time, it has good cold resistance, heat resistance, extraction resistance, volatile resistance and high growth rate.The products show excellent durability, soapy water resistance and low softness.Suitable as plasticizer of PVC resin, such as PVC cable material requiring high insulation.3. This product can be mixed with DOP in any proportion.4. When used in plasticizing paste, it can reduce viscosity and increase storage life.

Application Guide:

It is widely used in cable material, insulating skin, high-grade paint, coating, etc.
