Description

Dodecanedioic Acid, Polymer With 1,12-Dodecanediamine is a high-performance polyamide, specifically a nylon 6,12 polymer, known for its excellent balance of mechanical properties and chemical resistance. This material is critical for applications demanding durability, thermal stability, and low moisture absorption compared to other nylon types. It is primarily sought after by manufacturers in the engineering plastics, specialty coatings, and advanced fiber industries for producing components that require reliable performance under stress.

Application

• Engineering Plastics: Used in injection molding and extrusion for automotive components, electrical connectors, and industrial parts requiring high strength and dimensional stability.
• Monofilaments & Bristles: Ideal for producing tough, flexible monofilaments used in toothbrushes, paintbrushes, fishing lines, and surgical sutures.
• Hot-Melt Adhesives & Coatings: Serves as a key resin providing excellent adhesion, flexibility, and chemical resistance in powder coatings and adhesive formulations.
• Automotive Industry: Employed in under-the-hood applications, fuel lines, and various connectors due to its resistance to hydrocarbons and high-temperature performance.
• Packaging Films: Used to create high-barrier, multi-layer films for food and industrial packaging that require low gas permeability.
• 3D Printing Filaments: A premium material for fused deposition modeling (FDM) due to its layer adhesion, low warpage, and finished part strength.

Quality Control

Our Polyamide 6,12 is manufactured under a stringent quality management system. Each batch undergoes comprehensive testing for key parameters including intrinsic viscosity, melting point, moisture content, and residual monomer levels to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We can support compliance with relevant regulatory frameworks such as REACH, FDA (for indirect food contact), and RoHS 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 uptake, which can affect processing and final properties.
