Description

Isophthalic Acid Bis(2-Phenoxypropionylhydrazide) is a high-performance specialty chemical additive. This compound is valued for its role as a highly effective metal deactivator and antioxidant in polymer stabilization systems. It is primarily utilized by manufacturers in the plastics, synthetic fiber, and lubricant industries to enhance product longevity and performance under demanding conditions.

Application

• Polymer Stabilization: Acts as a metal deactivator and co-stabilizer in polyolefins (e.g., polyethylene, polypropylene) to prevent catalytic degradation from residual metal catalysts.
• Synthetic Fibers: Incorporated into nylon and polyester production to improve thermal stability during high-temperature processing and extrusion.
• Lubricant & Fuel Additive: Used in industrial lubricants and greases to chelate metal ions, preventing oxidation and sludge formation.
• Adhesives & Sealants: Enhances the long-term stability and performance of hot-melt and reactive adhesive formulations.
• Wire & Cable Insulation: Provides critical stabilization in polyethylene and cross-linked polyethylene (XLPE) compounds used for insulation, protecting against copper-catalyzed degradation.
• Engineering Plastics: Used as a stabilizer in high-performance engineering resins to maintain mechanical properties and color stability.

Quality Control

Our Isophthalic Acid Bis(2-Phenoxypropionylhydrazide) is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, performance, and compliance with customer specifications. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is easily oxidized (store under inert atmosphere) and is light-sensitive (store away from light). Keep away from strong oxidizing agents. For long-term storage, consider packaging under an inert gas such as nitrogen.
