Description

Poly(1,4-Cyclohexanedimethylene Terephthalate-Co-Ethylene Terephthalate) is a high-performance thermoplastic copolyester known for its excellent clarity, toughness, and chemical resistance. This material is engineered to bridge the gap between standard PET and more expensive engineering plastics, offering superior dimensional stability and a high glass transition temperature. It is a critical raw material for manufacturers in the packaging, automotive, and electronics industries seeking durable, transparent components.

Application

• High-Clarity Packaging: Used for manufacturing bottles, jars, and containers for cosmetics, personal care, and specialty foods requiring excellent barrier properties and visual appeal.
• Automotive Components: Serves as a material for interior trim, lighting assemblies, and under-hood parts due to its heat resistance and impact strength.
• Electrical & Electronics: Ideal for connectors, bobbins, and housings where good dielectric properties and resistance to soldering heat are essential.
• Medical Device Housings: Utilized for transparent or opaque medical device components that require sterilization compatibility and chemical resistance.
• Consumer Goods: Found in appliances, tool housings, and sporting goods that benefit from its durability and aesthetic finish.
• Films and Sheets: Processed into oriented films for lamination or thermoformed sheets for displays and protective covers.

Quality Control

Our Poly(1,4-Cyclohexanedimethylene Terephthalate-Co-Ethylene Terephthalate) is produced under a strict quality management system. Each batch is tested to ensure consistent performance in key parameters such as intrinsic viscosity, color, and thermal properties. Certificates of Analysis (COA) documenting these 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, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the original packaging sealed until use to prevent moisture absorption, which can affect processing and final product properties.
