Description

1,3-Benzenedicarboxylic Acid Polymer With 1,4-Cyclohexanedimethanol And Dimethyl 1,4-Benzenedicarboxylate is a high-performance, amorphous thermoplastic polyester with excellent clarity, chemical resistance, and dimensional stability. This material is engineered to deliver superior processability and robust mechanical properties, making it a critical component for demanding applications. It is essential for manufacturers in the packaging, medical device, and consumer electronics industries seeking durable, transparent, and reliable polymer solutions.

Application

• Medical Device Components: Used for housings, connectors, and fluid handling parts requiring clarity, sterilizability (via gamma or EtO), and biocompatibility.
• High-Clarity Packaging: Ideal for blister packs, clamshells, and transparent containers where impact resistance and product visibility are paramount.
• Consumer Electronics: Serves as a material for durable, scratch-resistant covers, lenses, and display components.
• Automotive Glazing & Lighting: Applied in interior lenses, light guides, and other components demanding optical clarity and heat resistance.
• Specialty Films & Sheets: Utilized to produce films for graphical overlays, membrane switches, and protective barriers.
• 3D Printing (FDM/FFF): Engineered filament grades offer high strength and minimal warping for functional prototypes and end-use parts.

Quality Control

Our 1,3-Benzenedicarboxylic Acid Polymer With 1,4-Cyclohexanedimethanol And Dimethyl 1,4-Benzenedicarboxylate is manufactured under a strict quality management system. Each batch is tested against rigorous internal specifications to ensure consistent performance in key areas such as intrinsic viscosity, color, thermal properties, and mechanical strength. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light and moisture. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents and heat sources. Prior to processing, the material should be properly dried according to the recommended technical data sheet to prevent hydrolysis and ensure optimal product performance.
