Diallyl Phthalate (DAP) is a chemical compound of significant industrial importance, serving critical roles as both a crosslinking agent and a plasticizer. NINGBO INNO PHARMCHEM CO.,LTD. provides this versatile chemical, enabling its use in a wide spectrum of advanced material applications. Understanding the fundamental properties and diverse applications of DAP is key to appreciating its value in modern manufacturing.

Chemically, Diallyl phthalate is a colorless to light yellow liquid with the molecular formula C14H14O4. Its structure features two allyl ether groups, which are the source of its reactivity. At room temperature, DAP is relatively stable, but upon heating or in the presence of an initiator, it readily undergoes polymerization and crosslinking reactions. This controlled reactivity is fundamental to its utility in creating high-performance polymers.

The applications of Diallyl phthalate are extensive and varied. As a crosslinking agent, it is widely used in unsaturated polyester resins, where it enhances properties such as heat resistance, dimensional stability, and electrical insulation. Compared to styrene, another common crosslinker, DAP provides a more robust material, especially in demanding electrical applications. Its role as an anti-gelling agent for vinyl monomers, like styrene, is also critical for process stability in polymerization reactions.

Furthermore, DAP functions effectively as an internal plasticizer for polymers such as PVC. This integration into the polymer matrix results in permanent plasticization, improving heat resistance, light stability, and solvent resistance. This makes DAP an excellent choice for sealants, flooring, and automotive components. The inherent stability and resistance properties of DAP-modified polymers ensure their longevity and reliable performance in challenging environments. NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying high-quality Diallyl phthalate, ensuring that industries can harness its full potential for innovation and product enhancement.
