About DINP (Diisononyl Phthalate)

 

DINP, short for Diisononyl Phthalate, is a widely used high-performance phthalate plasticizer. It is a clear, colorless, and oily liquid known for its excellent compatibility with various polymers, especially PVC.

 

DINP is valued for its superior flexibility, durability, and low-temperature performance. It provides enhanced resistance to migration and evaporation, ensuring long-lasting flexibility in finished products. This plasticizer is commonly used in applications requiring toughness and weather resistance.

 

Due to its balance of performance and cost-effectiveness, DINP is a preferred choice in many industrial and consumer applications.

DINP VS DOP

 

 

DINP	DOP
Lower volatility - better suited for high-temperature or long-lifespan applications	Higher volatility
Superior thermal and UV stability - better resistance to heat and sunlight	Moderate thermal and UV stability
Better aging resistance, suitable for outdoor use	Poor aging resistance

The Application of DINP

 

 

 

Outdoor Cable and Wire Sheathing

Automotive Interior Materials

Waterproof and Geomembranes

DINP is ideal for cable and wire applications that are exposed to prolonged sunlight, wind, and rain. It provides excellent UV resistance and thermal aging stability, ensuring long-term performance in harsh outdoor environments.

 

Commonly used in dashboard films, door seals, and floor mats, DINP performs well under extreme conditions such as intense summer heat and freezing winters, offering superior thermal and cold resistance.

 

DINP is widely used in applications such as pond liners, tunnel waterproofing membranes, landfill barriers, and agricultural irrigation films. It offers outstanding durability, flexibility, and weather resistance, making it a reliable choice for demanding environmental conditions.

 

 

 

 

Construction and Infrastructure Materials

Industrial Hoses and Sealing Components

Synthetic Leather and Outdoor Furniture Covers

DINP enhances the durability of roofing membranes, PVC flooring, and sealing strips. It performs reliably in regions with significant seasonal temperature fluctuations, preventing brittleness and minimizing material loss due to volatilization.

Used in air conditioning hoses, conveyor belts, and oil seals, DINP provides excellent resistance to oil, heat, and cold. Its high stability makes it ideal for long-term, high-stress industrial applications.

 

DINP helps maintain softness and flexibility in synthetic leather and coverings used for garden furniture and awnings. It resists degradation from prolonged exposure to sunlight, heat, and moisture.
