Description

1,3-Benzenedicarboxylic Acid, Polymer With 1,4-Benzenedicarboxylic Acid And 1,6-Hexanediamine CAS NO 25750-23-6 is a high-performance polyamide copolymer, commonly known as a type of nylon 6T/6I, synthesized from isophthalic acid, terephthalic acid, and hexamethylenediamine. This engineered polymer is valued for its exceptional thermal stability, chemical resistance, and robust mechanical properties, making it a critical material for demanding industrial applications. It is primarily sought after by manufacturers in the automotive, electronics, and industrial fiber sectors for components that must perform reliably under high stress and temperature.

Application

• High-Temperature Automotive Components: Used in under-the-hood parts, connectors, and housings requiring long-term thermal and chemical resistance.
• Electrical and Electronic Insulation: Ideal for circuit board components, connectors, and insulating films due to its excellent dielectric properties and dimensional stability.
• Industrial and Technical Fibers: Serves as a base polymer for producing high-strength, heat-resistant fibers used in filtration, protective apparel, and advanced composites.
• Engineering Plastics and Resins: A key raw material for injection-molded or extruded parts in machinery and equipment that demand high mechanical strength and low moisture absorption.
• Specialty Films and Coatings: Utilized in applications requiring a barrier with good thermal and chemical resistance.

Quality Control

Our production of this polyamide copolymer adheres to stringent quality management systems. Each batch undergoes comprehensive analysis to ensure consistency in key parameters such as intrinsic viscosity, melting point, and thermal stability. Certificates of Analysis (COA) detailing purity, molecular weight distribution, and residual monomer content are available upon request to support your quality assurance and regulatory compliance needs.

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 and final properties.
