Description

Hexamethylene Sebacate Polymer is a high-performance, linear aliphatic polyester synthesized from hexamethylene glycol and sebacic acid. This material is valued for its excellent flexibility, hydrolytic stability, and biocompatibility, making it a critical component in advanced material formulations. It is primarily sought by manufacturers in the medical device, specialty coatings, and biodegradable plastics industries for creating durable and predictable polymer matrices.

Application

• Biomedical Implants & Devices: As a key monomer or prepolymer for synthesizing biodegradable sutures, drug delivery matrices, and soft tissue scaffolds.
• High-Performance Elastomers & TPUs: Used to impart flexibility, low-temperature performance, and hydrolysis resistance in thermoplastic polyurethane (TPU) formulations for cables, hoses, and films.
• Specialty Adhesives & Sealants: Serves as a building block for polyurethane-based adhesives requiring good moisture resistance and mechanical strength.
• Biodegradable & Bio-based Plastics: A fundamental component in the production of aliphatic polyesters (e.g., PBS-type copolymers) for compostable packaging and agricultural films.
• Engineered Coatings: Incorporated into coating resins to enhance flexibility, adhesion, and chemical resistance on various substrates.
• Polymer Modification: Acts as a plasticizer or compatibilizer to improve the toughness and processability of other polymer blends.

Quality Control

Our Hexamethylene Sebacate Polymer is manufactured under a strict quality management system. Each batch is characterized for critical parameters including molecular weight distribution, acid value, hydroxyl value, and thermal properties to ensure consistency and performance. Certificates of Analysis (COA) with detailed specifications are provided for every shipment, supporting applications in regulated industries.

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) and should be kept under dry conditions to prevent hydrolysis and molecular weight degradation. Keep away from strong oxidizing agents.
