Description

Zinc Phthalate is an organometallic salt derived from phthalic acid, serving as a versatile intermediate and functional additive in various industrial processes. Its primary value lies in its role as a heat stabilizer and catalyst precursor, offering enhanced performance and stability in polymer formulations. This product is essential for manufacturers in the plastics, coatings, and specialty chemical industries seeking reliable and consistent raw materials for their production needs.

Application

• Primary heat stabilizer and co-stabilizer in polyvinyl chloride (PVC) and other halogenated polymer systems.
• Catalyst and catalyst precursor in organic synthesis and esterification reactions.
• Functional additive in the production of specialty coatings and paints to improve film properties.
• Intermediate in the synthesis of other metal phthalate complexes and coordination compounds.
• Component in flame-retardant formulations for plastics and textiles.
• Additive in lubricant and grease formulations to enhance performance under high temperatures.

Quality Control

Our Zinc Phthalate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, identification, and impurity profile analysis, to meet exacting industry standards. A detailed Certificate of Analysis (COA) documenting purity, physical characteristics, and test results is provided with every shipment to guarantee product integrity and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product performance and flow characteristics. Keep away from incompatible materials such as strong acids and strong oxidizing agents.
