Description

1,4-Benzenedicarboxylic Acid, Polymer With 1,6-Hexanediamine And Hexanedioic Acid is a high-performance polyamide copolymer, commonly known as a nylon 6T/66 copolymer, synthesized from terephthalic acid, hexamethylenediamine, and adipic acid. This engineered polymer is valued for its exceptional thermal stability, mechanical strength, and chemical resistance, making it a superior material for demanding engineering applications. It is primarily sought by manufacturers in the automotive, electronics, and industrial components sectors for producing heat-resistant and durable parts.

Application

• Automotive Components: Used in under-the-hood parts, connectors, and housings requiring high heat deflection temperatures and dimensional stability.
• Electrical & Electronic (E&E): Ideal for surface-mount technology (SMT) connectors, bobbins, and circuit breakers due to its excellent dielectric properties and solder resistance.
• Industrial Machinery: Manufactured into gears, bearings, and wear strips that operate under high stress and temperature conditions.
• Consumer Appliances: Employed in components for irons, power tools, and other devices where heat resistance and strength are critical.
• Filaments and Fibers: Serves as a base resin for high-tenacity industrial fibers and advanced 3D printing filaments.
• Aerospace and Defense: Utilized in specialized components that must withstand extreme environments while maintaining lightweight properties.

Quality Control

Our production of Nylon 6T/66 copolymer adheres to stringent quality management systems, ensuring batch-to-batch consistency for critical engineering applications. Key parameters such as intrinsic viscosity, melting point, and thermal stability are rigorously tested. A Certificate of Analysis (COA) detailing specific lot specifications is provided with every shipment to guarantee compliance with your technical requirements.

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 absorption, which can affect processing and final properties.
