Product Features

Dioctyl Terephthalate (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.

DOTP 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.

DOTP can be mixed with DOP in any proportion. When used in plasticizing paste, it

can reduce viscosity and increase storage life.

Product Applications

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