Description

1,3-Benzenedicarboxylic Acid, Polymer With 1,4-Benzenedicarboxylic Acid, 1,6-Hexanediamine And Hexanedioic Acid is a high-performance, semi-aromatic polyamide copolymer, commonly known as PA 6T/6I or Polyamide 6T/6I. This engineered material is valued for its exceptional thermal stability, chemical resistance, and excellent mechanical properties, making it a superior alternative to standard aliphatic nylons. It is primarily sought by manufacturers in the automotive, electronics, and industrial sectors for demanding applications that require durability under high-temperature and harsh chemical environments.

Application

• Automotive Components: Used for under-the-hood parts, connectors, and housings requiring high heat resistance and strength.
• Electrical & Electronics (E&E): Ideal for surface-mount technology (SMT) connectors, bobbins, and circuit breakers due to its excellent dimensional stability and solder reflow resistance.
• Industrial Machinery: Manufactured into gears, bearings, and pump components that must withstand wear, friction, and exposure to oils and coolants.
• Consumer Appliances: Employed in parts for irons, coffee makers, and other devices where high-temperature performance is critical.
• Sporting Goods: Used in high-stress components for equipment that benefits from a high strength-to-weight ratio and toughness.
• Films & Fibers: Processed into specialized films and fibers for filtration and industrial textiles requiring thermal and chemical stability.

Quality Control

Our production of Polyamide 6T/6I follows stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as intrinsic viscosity, melting point, and thermal stability are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing purity, mechanical properties, and residual monomer content is provided with each shipment to support your quality assurance processes.

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 polymer is hygroscopic (moisture-sensitive); keep the original packaging sealed until use to prevent moisture absorption, which can affect processing and final properties.
