Description

1,3-Benzenedicarboxylic Acid, Polymer With 1,4-Benzenedicarboxylic Acid And 1,6-Hexanediol is a high-performance copolyester resin, specifically a poly(hexamethylene isophthalate-co-terephthalate). This engineered polymer is valued for its excellent balance of mechanical properties, chemical resistance, and thermal stability. It is a critical raw material for manufacturers in the coatings, adhesives, and specialty plastics industries seeking durable and reliable polymeric components.

Application

• Powder Coatings: As a key resin binder for durable, weather-resistant, and high-gloss finishes on automotive parts, appliances, and architectural aluminum.
• Hot-Melt Adhesives: Providing strong bonding strength, flexibility, and resistance to creep in packaging, bookbinding, and product assembly applications.
• Engineering Plastics & Composites: Used as a modifier or primary polymer to enhance toughness, dimensional stability, and chemical resistance in compounded materials.
• Industrial & Protective Coatings: Formulating high-performance liquid coatings for metal protection, pipe linings, and industrial equipment requiring corrosion resistance.
• Inks and Toners: Serving as a fusable resin component in electrophotographic toners and specialty printing inks.
• Filaments for 3D Printing (FDM): As a base material for producing technical filaments that require specific thermal and mechanical properties.

Quality Control

Our production of 1,3-Benzenedicarboxylic Acid, Polymer With 1,4-Benzenedicarboxylic Acid And 1,6-Hexanediol adheres to a strict quality management system. Each batch is characterized for critical parameters including intrinsic viscosity, acid value, glass transition temperature (Tg), and melting point to ensure consistent performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee compliance with your formulation requirements.

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). Keep away from strong oxidizing agents, strong acids, and strong bases. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption which can affect processing properties.
