Description

1,3-Benzenedicarboxylic Acid, Polymer With 1,4-Butanediol, Dimethyl 1,4-Benzenedicarboxylate And Hexanedioic Acid is a high-performance copolyester resin, specifically a poly(butylene adipate-co-terephthalate) or PBAT variant, engineered for its exceptional balance of properties. This polymer is crucial for formulators seeking to enhance the flexibility, toughness, and biodegradability of their end products. It is primarily needed by manufacturers in the packaging, agricultural film, and specialty plastics industries who require sustainable material solutions without compromising on performance.

Application

• Biodegradable and Compostable Packaging Films: Used as a key component in the production of flexible films for shopping bags, food packaging, and agricultural mulch films that meet international compostability standards (e.g., EN 13432, ASTM D6400).
• Polymer Modification and Blending: Acts as a bio-based plasticizer and toughening agent when blended with other biopolymers like PLA (Polylactic Acid) to improve impact resistance and elongation at break.
• Specialty Molding and Extrusion Compounds: Formulated into compounds for injection molding or extrusion to manufacture disposable cutlery, rigid containers, and other molded articles requiring biodegradability.
• Adhesive and Coating Formulations: Serves as a resin base in environmentally friendly adhesive and coating systems, providing good film-forming characteristics and substrate adhesion.
• Fiber and Nonwoven Fabric Production: Utilized in the melt-spinning process to produce biodegradable fibers for hygiene products, geotextiles, and filtration media.
• 3D Printing Filaments: Incorporated into specialty filaments for fused deposition modeling (FDM) to create prototypes and end-use parts with defined biodegradation profiles.

Quality Control

Our 1,3-Benzenedicarboxylic Acid, Polymer With 1,4-Butanediol, Dimethyl 1,4-Benzenedicathoxylate And Hexanedioic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters including intrinsic viscosity, melt flow index, thermal properties (DSC), and compositional analysis to ensure consistency and performance. Certificates of Analysis (COA) detailing lot-specific results are available upon request, and production can be aligned with relevant industry standards for biodegradable plastics.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat sources and open flames. For long-term storage, consider using a nitrogen blanket to minimize oxidative degradation. Keep the original packaging sealed until use to prevent moisture absorption.
