Description

1,3-Benzenedicarboxylic Acid, Polymer With 1,4-Benzenedicarboxylic Acid, 1,2-Ethanediol And .Alpha.-Hydro-.Omega.-Hydroxypoly(Oxy-1,2-Ethanediyl) is a specialized copolyester, commonly known as a modified polyethylene terephthalate (PET) or PETG-type resin, valued for its enhanced processing characteristics and material properties. This polymer is engineered to offer superior clarity, impact resistance, and chemical stability compared to standard polyesters, making it a critical material for demanding applications. It is primarily sought by manufacturers in the packaging, specialty films, and industrial plastics sectors who require high-performance, durable, and visually appealing polymer solutions.

Application

• High-Clarity Packaging: Used in the production of bottles, containers, and clamshells for food, cosmetics, and pharmaceuticals where product visibility and chemical resistance are paramount.
• Specialty Films and Sheets: Serves as a base resin for thermoformed sheets and extruded films requiring excellent toughness, low haze, and good barrier properties.
• Medical Device Components: Utilized in manufacturing parts that require sterilization compatibility, clarity, and durability, such as fluid reservoirs and device housings.
• 3D Printing Filaments: Acts as a premium material for fused deposition modeling (FDM) due to its strength, minimal warpage, and ease of printing.
• Industrial Parts and Components: Applied in injection molding for technical parts that demand a combination of mechanical strength, dimensional stability, and resistance to oils and chemicals.
• Consumer Goods: Found in durable goods like toys, display cases, and office supplies that benefit from its shatter resistance and aesthetic finish.

Quality Control

Our copolyester resin is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Key parameters such as intrinsic viscosity, color, and thermal properties are rigorously tested. A Certificate of Analysis (COA) detailing specific lot results is provided with every shipment. Our production adheres to relevant ISO standards, and we can support compliance requirements for food contact and medical applications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from strong oxidizing agents and excessive heat sources to prevent degradation of polymer properties. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to maintain product integrity.
