Description

Adipicacid-1,3Benzenedimethanaminecopolymer CAS NO 25805-74-7 is a high-performance polyamide resin synthesized from adipic acid and m-xylylenediamine (1,3-benzenedimethanamine). This specialized copolymer is engineered to deliver exceptional barrier properties, chemical resistance, and mechanical strength, making it a critical material for demanding industrial applications. It is primarily sought by manufacturers in the packaging, automotive, and electronics industries for creating advanced, durable components and films.

Application

• High-Barrier Packaging Films: Used as a core layer in multi-layer films for food and pharmaceutical packaging to provide superior oxygen and aroma barrier properties.
• Automotive Fuel Systems: Employed in the manufacture of fuel lines, connectors, and barrier layers in plastic fuel tanks due to its excellent resistance to hydrocarbons and alcohols.
• Electrical & Electronic Components: Serves as an insulation material and protective coating for wires, connectors, and circuit boards, offering good dielectric properties and heat resistance.
• Industrial Hoses and Tubes: Formulated into flexible and rigid tubing for chemical transfer, hydraulic systems, and pneumatic applications.
• Metal Coatings: Used in powder coatings and primers to provide a tough, corrosion-resistant finish for metal substrates.
• Engineering Plastics: Incorporated as a modifier or base resin in compounded materials to enhance dimensional stability, wear resistance, and thermal performance.

Quality Control

Our Adipicacid-1,3Benzenedimethanaminecopolymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters including intrinsic viscosity, melting point, moisture content, and color to ensure consistency and performance. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

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 to prevent moisture absorption which can affect processing and final properties.
