Description

Tetrachlorophthalic Anhydride, Glycerin, Ethylene Glycol Polymer is a specialized polymeric ester derived from tetrachlorophthalic anhydride, glycerin, and ethylene glycol, designed to impart unique chemical resistance and thermal stability to formulations. This engineered polymer is critical for applications requiring durable, halogenated polymeric matrices that offer enhanced flame retardancy and low smoke generation. It serves as a key functional additive and resin component for advanced material scientists and formulators in the coatings, electronics encapsulation, and specialty plastics industries.

Application

• As a flame-retardant resin modifier and cross-linking agent in epoxy and polyester systems for electrical laminates and circuit boards.
• Utilized in the formulation of high-performance, halogenated coatings for industrial and marine environments requiring exceptional chemical and corrosion resistance.
• Serves as a reactive intermediate or additive in the synthesis of specialty plasticizers and stabilizers for PVC and other engineering polymers.
• Key component in encapsulation and potting compounds for electronic components, providing electrical insulation and thermal protection.
• Used in the development of adhesives and sealants with enhanced durability and resistance to harsh chemicals and elevated temperatures.
• Potential application as a functional additive in intumescent coatings and fire-protective materials to improve char formation and fire resistance.

Quality Control

Our Tetrachlorophthalic Anhydride, Glycerin, Ethylene Glycol Polymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assessment of key parameters such as acid value, hydroxyl value, halogen content, and viscosity. Certificates of Analysis (COA) documenting full specifications are available upon request 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 at room temperature (15-25°C). Keep away from strong bases, strong oxidizing agents, and sources of heat or ignition. The container must be kept tightly sealed due to potential moisture sensitivity.
