Description

1,3-Benzenedicarboxylic Acid Polymer With 1,4-Benzenedicarboxylic Acid, 1,4-Butanediol, 2,2-[1,2-Ethanediylbis(Oxy)]Bis[Ethanol] And 2,2′-Oxybis[Ethanol] is a high-performance, specialized copolyester designed for advanced material applications. This engineered polymer offers a unique balance of thermal stability, mechanical strength, and chemical resistance, making it a critical component for demanding industrial formulations. It is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producers of specialty plastics and composite materials seeking to enhance product performance.

Application

• High-Performance Coatings and Resins: Used as a key building block in powder coatings, coil coatings, and industrial finish formulations requiring excellent weatherability and durability.
• Specialty Adhesives and Sealants: Imparts flexibility, adhesion, and chemical resistance to hot-melt and reactive adhesive systems for automotive, construction, and packaging.
• Engineering Thermoplastics and Elastomers: Serves as a modifier or primary component in thermoplastic polyurethanes (TPU), copolyesters, and other polymers to tailor flexibility, melt viscosity, and end-use properties.
• Composite Materials: Utilized in the matrix or as a compatibilizer for fiber-reinforced plastics (FRP) to improve interfacial adhesion and mechanical performance.
• Textile and Fiber Finishing: Acts as a polymeric additive for fiber coatings and non-woven binders to provide water resistance and durability.
• Ink and Toner Formulations: Employed as a resin component to enhance pigment dispersion, gloss, and substrate adhesion in specialty printing applications.

Quality Control

Our production of this specialty copolyester adheres to a stringent quality management system to ensure batch-to-batch consistency and performance reliability. All materials are manufactured and tested against precise internal specifications, which typically include parameters for acid value, hydroxyl value, viscosity, color, and thermal properties. A Certificate of Analysis (COA) detailing these results is 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, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product properties.
