Description

1,3-Benzenedicarboxylic Acid, Polymer With 1,4-Benzenedicarboxylic Acid, 1,4-Cyclohexanedimethanol And 2-Methyl-1,3-Propanediol is a high-performance, amorphous thermoplastic copolyester engineered for superior durability and chemical resistance. This polymer is valued for its excellent balance of clarity, toughness, and thermal stability, making it a critical material for demanding applications. It is primarily sought by manufacturers in the packaging, consumer goods, and specialty film industries seeking to enhance product performance and longevity.

Application

• High-Clarity Packaging: Used in the production of rigid and flexible packaging for food, cosmetics, and pharmaceuticals where excellent barrier properties and visual appeal are required.
• Durable Consumer Goods: Serves as a key material for injection-molded components in appliances, tools, and personal care items due to its impact resistance and dimensional stability.
• Specialty Films and Sheets: Employed in extrusion processes to create films for graphic arts, protective layers, and industrial laminates.
• Medical Device Housings: Utilized for non-implantable medical device components that require repeated sterilization and chemical compatibility.
• Automotive Interiors: Applied in interior trim and functional parts where a combination of aesthetic finish, scratch resistance, and heat tolerance is necessary.
• Optical Components: Suitable for light guides, lenses, and display components owing to its inherent clarity and good light transmission properties.

Quality Control

Our copolyester products are manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Key parameters such as intrinsic viscosity (IV), color, thermal properties, and monomer content are rigorously tested. Certificates of Analysis (COA) documenting full specifications are available for every shipment, and we can support compliance with relevant food contact and regulatory standards upon request.

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 original packaging sealed until use to prevent moisture absorption, which can affect processing and final product properties.
