Description

Poly(1,4-Cyclohexylenedimethylene) Terephthalate is a high-performance thermoplastic polyester, also known as PCT, derived from terephthalic acid and 1,4-cyclohexanedimethanol. This material is engineered to deliver exceptional thermal stability, chemical resistance, and mechanical properties, making it a superior choice for demanding engineering applications. It is primarily sought after by manufacturers in the electronics, automotive, and specialty packaging industries who require materials that can withstand high-temperature environments and aggressive chemicals.

Application

• High-Temperature Electrical Connectors and Sockets: Used for surface-mount technology (SMT) components due to its excellent heat resistance and dimensional stability during soldering processes.
• Automotive Under-the-Hood Components: Ideal for sensor housings, ignition systems, and other parts exposed to elevated temperatures and automotive fluids.
• Specialty Films and Packaging: Employed in applications requiring high clarity, barrier properties, and resistance to sterilization methods.
• Industrial and Consumer Appliance Parts: Used in components for irons, coffee makers, and power tools where heat resistance and strength are critical.
• Optical Lenses and Light Guides: Suitable for applications benefiting from its good optical properties and thermal performance.
• Fibers for Technical Textiles: Used in the production of fibers requiring high strength and thermal stability.

Quality Control

Our Poly(1,4-Cyclohexylenedimethylene) Terephthalate is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency in key parameters such as intrinsic viscosity, thermal properties (DSC/TGA), and color. Certificates of Analysis (COA) detailing lot-specific results are provided to guarantee compliance with your technical specifications.

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. For long-term storage, a nitrogen blanket is recommended to prevent thermal-oxidative degradation.
