Dioctyl Terephthalate (DOTP) is a high-performance plasticizer, mainly used in the processing of polyvinyl chloride (PVC) plastics.
The following is the detailed introduction of DOTP:
Basic characteristics:
DOTP is a colorless, odorless, non-toxic transparent oily liquid that is insoluble in water but soluble in general organic solvents.
It has high heat resistance, cold resistance and electrical insulation, and is suitable for environments with high temperature and high electrical insulation requirements.
Low volatility and difficulty in extraction ensure the stability and durability of the product.
Excellent softness and anti-extraction properties improve the hardness and deformation of the product.
Environmental advantages of Dioctyl Terephthalate (DOTP):
DOTP does not contain phthalates and is an excellent environmentally friendly plasticizer, which is in line with the current environmental protection trend.
Due to the small amount of waste generated during its production process, it has little impact on the environment and is in line with the concept of sustainable development.
Application areas of Dioctyl Terephthalate (DOTP):
Used in the production of cable materials, PVC products, and artificial leather films.
Due to its excellent electrical insulation and softness, DOTP has broad application prospects in the fields of wires and cables, artificial leather, etc.
In addition, DOTP is also used as a high-quality lubricant or lubricating additive for PVC products in cars, paints, coatings for high-end furniture and interior decoration, and precision instruments.
Specific uses of Dioctyl Terephthalate (DOTP):
• Plasticizer for polyvinyl chloride (PVC) plastics:
DOTP is an excellent main plasticizer for PVC plastics. Compared with the commonly used diisooctyl phthalate (DOP), it has the advantages of heat resistance, cold resistance, low volatility, anti-extraction, flexibility and good electrical insulation. This makes DOTP show excellent durability, soap water resistance and low-temperature flexibility in products.
• Application of cable materials:
Due to its low volatility and high thermal stability, widely used as an ideal plasticizer for the production of 70 degrees Celsius temperature-resistant cable materials and other PVC products that require volatility resistance. Its volume resistivity is 10-20 times higher than that of DOP, and it has excellent migration resistance.
• Artificial leather and coating additives:
In paints and coatings for high-end furniture and interior decoration, DOTP is used as a high-quality lubricant or lubricating additive, as well as a nitro lacquer additive.
• Other PVC products:
Used to produce polyvinyl chloride cable materials, insulation skins, high-grade paints, coatings, etc. In addition, also used in PVC products in cars, which can solve the problem of fogging of glass windows and improve the clarity of vision in the car.
