High-Performance Industrial Plasticizer DBP with Excellent Solubility for PVC
Product Overview
Dibutyl Phthalate (DBP) - High-Performance Industrial Plasticizer
CAS: 84-74-2
Molecular Formula: C₁₆H₂₂O₄
Molecular Weight: 278.35
This premium plasticizer is primarily engineered for cellulose resins and polyvinyl chloride (PVC). It is exceptionally suited for nitrocellulose coatings, offering superior solubility, dispersibility, and adhesion properties. Its excellent pigment compatibility and ability to enhance the resilience of natural and synthetic rubbers make it an essential additive for high-quality chemical formulations.
Key Advantages
- Ultra-high plasticizing efficiency, less dosage to reach soft texture
- Excellent solubility, dispersibility and adhesion for nitrocellulose coatings
- Great compatibility with PVC, cellulose resin, pigment & synthetic rubber
- Improves product elasticity and resilience for rubber manufacturing
- Delivers smooth, stable, soft paint film with uniform coloring effect
- Low initial viscosity, stable performance for plastisol paste production
- Cost-effective universal primary plasticizer for multiple industries
- High purity ≥99.5%, light color, stable industrial quality
Performance & Applications
Primarily used as main plasticizer for cellulose resins and polyvinyl chloride, especially suitable for nitrocellulose coatings with excellent solubility, dispersibility, and adhesion.
Produces paint films with good softness and stability (general dosage: 10% to 60% depending on transparency and coloring requirements).
Excellent compatibility with pigments for coloring films, synthetic leather, and plastic products.
Effective plasticizer and softener for natural and synthetic rubber, improving product resilience.
Important Note: This product has relatively high volatility and oil extraction, resulting in relatively poor durability. Please select appropriately for your application.
Application Guide
Widely used in PVC water pipes, trachea, snake skin pipes, plastic shoes, water hoses, glue, printing conveyor belts, paints, coatings, organic glass, colored films, and various industrial applications.
