DINP (CAS 28553-12-0) is a high-performance, versatile plasticizer and chemical additive used across multiple industries. It is a key plasticizing agent that enhances the flexibility, toughness, and processability of polymer materials (especially polyvinyl chloride, PVC). It can form stable blends with resins, improving material performance while maintaining long-term stability. It can also be applied in pharmaceuticals, coatings, and other products to boost compatibility and durability.
1. Excellent plasticizing performance: Enhances flexibility, toughness, and low-temperature resistance of polymer materials (e.g., PVC). Maintains good elasticity of products even at -20°C, outperforming traditional plasticizers like DOP.
2. Strong thermal stability: Boasts a high thermal decomposition temperature (over 280°C), remaining stable during high-temperature processing (e.g., PVC extrusion/injection molding). Avoids product discoloration or performance degradation caused by plasticizer decomposition.
3. Low volatility: Features minimal vapor pressure at room temperature, reducing plasticizer loss during product storage and use. Helps maintain long-term performance stability (e.g., prevents PVC cables from hardening and becoming brittle).
4. Broad compatibility: Mixes well with most polymer materials (PVC, PVA, cellulose acetate) and can be blended with other plasticizers (DOTP, DBP) in any ratio. Adapts to diverse product performance requirements.
5. Simple application method: Easy to add during production (liquid form), requiring no complex processes. Convenient for large-scale industrial use and batch production.
DINP, a phthalate ester plasticizer, functions by integrating with polymer molecular chains to reduce intermolecular forces — a compatibility-driven plasticizing process that softens rigid resins like PVC.
*Density (20°C): 0.982 g/cm³
*pH Range: Neutral (6.5–7.5 in aqueous emulsion, stable in most processing systems)
*Concentration: Typically 30–60% (by weight) in flexible PVC products, adjusted per material rigidity needs
*Odor: Slight, characteristic ester-like scent (odorless in finished plasticized products)
*Appearance: Clear, impurity-free oily liquid
*Color (Platinum-Cobalt Scale): 20
*Ester Content: ≥99.5%
*Acid Value: 0.01 mgKOH/g
*Moisture Content: 0.015%
*Flash Point (Open Cup Method): 235°C
Used as a plasticizer in plastics, wires/cables, and automotive parts, with strict standards for purity, safety, and performance (e.g., REACH, FDA for food-contact materials).
DINP is a high-performance, versatile plasticizer. It effectively enhances the flexibility, toughness, and processability of polymer materials (especially PVC). As a core plasticizing additive, it can improve the mechanical properties and durability of products across multiple industries.
It works by integrating with polymer molecular chains to reduce intermolecular friction and rigidity — this softens rigid resins, while also maintaining stable performance under temperature fluctuations and long-term use. It exhibits excellent compatibility with most polymer materials, ensuring consistent product quality.
1. Plastic Industry: Used in flexible PVC products (cables, hoses, films, toys) to provide long-lasting flexibility and low-temperature resistance.
2. Wire & Cable Sector: Applied in PVC insulation/sheathing materials to boost electrical insulation and aging resistance.
3. Automotive Field: Utilized in interior parts (door panels, dashboard cushions) and hoses to enhance heat resistance and mechanical strength.
4. Coatings & Inks: Added to formulations to improve flexibility and adhesion, preventing cracking of dried coatings.
5. Medical Devices: Used in PVC medical products (infusion tubes, blood bags) that meet safety standards (e.g., FDA), ensuring biocompatibility and performance stability.
