At NINGBO INNO PHARMCHEM CO.,LTD., we are dedicated to advancing industries through high-performance chemical solutions. One of the most versatile products in our portfolio is Diallyl Phthalate (DAP), a multifunctional monomer identified by its CAS number 131-17-9. This compound is a clear, colorless to slightly yellow oily liquid, recognized for its mild odor and low volatility. Its unique chemical structure, featuring two unsaturated alkenyl groups, makes it an invaluable component in a wide range of polymerization processes.

A key characteristic of DAP monomer is its remarkable stability at room temperature, which allows for safe storage without the need for polymerization inhibitors. However, when subjected to high temperatures or initiators, it readily polymerizes to form a linear polymer, a property that is harnessed across numerous applications. DAP is soluble in most common organic solvents such as ethanol, acetone, and toluene, but it is insoluble in water. Its high boiling point (165-167 °C at 5 mmHg) and low melting point (-70 °C) further define its physical profile for industrial handling and use.

The applications for Diallyl Phthalate are extensive and diverse, highlighting its importance in modern manufacturing. These include:
1. Unsaturated Polyester Resin Crosslinking Agent: DAP is widely used as a crosslinking agent for unsaturated polyester resins. Its inclusion significantly enhances the final product's electrical properties, heat resistance, and dimensional stability, making it ideal for high-performance electrical components and laminates.

2. PVC Internal Plasticizer: Within PVC resin formulations, DAP acts as an internal plasticizer. Unlike external plasticizers, it becomes a permanent part of the polymer matrix, resulting in superior heat resistance, light resistance, solvent resistance, and electrical properties in the finished PVC products.

3. Acrylic Resin Modifier: When incorporated into acrylic resins, DAP improves several key characteristics. It boosts adhesion, water resistance, gloss, and overall flow, making it a valuable additive for producing high-quality coatings, adhesives, and sealants.

4. Synthetic Rubber Auxiliary: DAP also functions as an effective auxiliary crosslinking agent in the production of synthetic rubber, contributing to the durability and performance of the final rubber products.

5. Prepolymer Production: DAP can be polymerized to form a prepolymer. This Diallyl Phthalate prepolymer is a stable, solid material used in thermosetting molding plastics, which are valued for their excellent electrical insulation and stability under harsh conditions. It is also a critical ingredient in UV-curable inks and coatings.

6. Anti-Gelling Agent: Thanks to its inherent stability, DAP is an effective anti-gelling agent for other vinyl monomers like styrene and vinyl esters, preventing premature polymerization during storage and transport.

The versatility and high performance of Diallyl Phthalate (DAP) make it an indispensable chemical for innovators across various sectors.
