High Purity Diisononyl Phthalate DINP Primary Plasticizer Excellent Insulation

DINP Plasticizer with Superior Electrical Insulation for PVC Processing

Dinonyl Phthalate (DINP)
CAS: 28553-12-0
Chemical Formula: C₂₆H₄₂O₄
Molecular Weight: 418.61

DINP offers superior performance compared to DOP, featuring lower volatilization weight loss and excellent intrinsic viscosity stability. It is the ideal choice for high-efficiency plastic processing.

• Low Volatility: Much less volatile weight loss compared to traditional DOP plasticizer
• Outstanding Cold Flexibility: Delivers great low-temperature softness for finished PVC goods
• Safe & Mild Toxicity: Low-toxic formula compliant for toy and daily contact plastic products
• Premium Water Resistance: Finished plastic items gain reliable anti-water permeation performance
• Superior Electrical Insulation: Perfect insulation property for wire and cable raw materials
• Wide Material Compatibility: Matches well with PVC resin, artificial leather and coating formulations
• Long Service Life: Slight migration extends the durability of films, sheets and profiles
• Versatile Multi-scene Use: Adaptable for industrial films, flooring, waterproof cloth and wall coverings
• Stable Long-term Storage: Plastisol paste keeps steady viscosity with no sharp viscosity rise over time
• Cost-effective Main Plasticizer: Balanced performance and price for mass plastic manufacturing

1. Compared to DOP, DINP has lower volatilization weight loss and similar intrinsic viscosity. When used alone, it will be higher.
2. DINP is more suitable for plastic processing, showing better viscosity stability, can disperse foam without any problems, and has a lower melting temperature. As a PVC coating, it has the lowest initial viscosity and minimal viscosity variation.
3. DINP has low volatility and excellent low softness, but slightly inferior to DIDP.
4. Mainly used for PVC, and due to its good water resistance, low toxicity, and excellent electrical insulation performance, the products produced with this product are widely used in toy films, wires, and cables.
