Description

Diallyl Phthalate is a high-purity, reactive diester monomer widely used in polymer synthesis and cross-linking applications. Its bifunctional structure, featuring two allyl groups, makes it a valuable precursor for creating thermosetting resins with excellent heat resistance and mechanical properties. This compound is essential for manufacturers in the plastics, coatings, and specialty adhesives industries seeking to enhance product durability and performance.

Application

• Primary monomer for the production of allyl resins and thermosetting plastics.
• Cross-linking agent and co-monomer in the synthesis of unsaturated polyester resins (UPR) for reinforced composites.
• Plasticizer and modifier for specialty polyvinyl chloride (PVC) and other polymer systems to improve flexibility and processability.
• Key intermediate in the manufacture of high-performance coatings, sealants, and adhesives requiring thermal stability.
• Used in the production of electrical laminates and insulating materials.
• Component in dental materials and other medical-grade polymer formulations.
• Research and development chemical for novel polymer architectures and controlled release applications.

Quality Control

Our Diallyl Phthalate is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques including GC, HPLC, and IR spectroscopy for comprehensive characterization. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Recommended storage temperature is 15-25°C. The product has limited shelf life under these conditions; use on a first-in, first-out (FIFO) basis.
