Product Features
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.
