Description

Dodecanedioic Acid, Polymer With 6-Aminohexanoic Acid, Decanedioic Acid, 1,6-Hexanediamine And Hexanedioic Acid CAS NO 71215-68-4 is a high-performance polyamide copolymer engineered for demanding industrial applications. This specialty polymer offers a unique balance of thermal stability, chemical resistance, and mechanical properties derived from its multi-monomer composition. It is a critical material for manufacturers in the plastics, coatings, and advanced materials sectors seeking to enhance product durability and performance.

Application

• High-Performance Engineering Plastics: Used as a key component in the production of specialty nylons (e.g., PA 6,12, PA 6,10, PA 6,6) for automotive parts, electrical connectors, and industrial components requiring excellent dimensional stability and resistance to fuels and oils.
• Hot-Melt Adhesives: Serves as a base polymer providing strong bonding strength, flexibility, and heat resistance for applications in packaging, textiles, and footwear manufacturing.
• Powder Coatings: Imparts superior flow, leveling, and corrosion resistance to decorative and protective coatings for metal substrates in architectural and industrial finishes.
• Films and Fibers: Utilized in the extrusion of specialty films for flexible packaging and high-tenacity fibers for technical textiles and filtration media.
• Resin Modifier: Acts as an additive to improve the toughness, impact resistance, and thermal properties of other polymer systems, including epoxies and polyesters.
• 3D Printing Filaments: Formulated into advanced filaments for fused deposition modeling (FDM) that offer enhanced layer adhesion, low warpage, and chemical resistance for functional prototypes and end-use parts.

Quality Control

Our production of this polyamide copolymer adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including intrinsic viscosity, melting point, amine end-group concentration, and relative viscosity. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

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 container tightly sealed when not in use to prevent moisture absorption, which can affect processing characteristics and final product properties.
