Description

1,3-Benzenedicarboxylic Acid Polymer With 1,4-Benzenedenecarboxylic Acid, 1,6-Hexanediamine And 4,4'-Methylenebis[Cyclohexanamine] is a high-performance, semi-aromatic polyamide copolymer, commonly known as a transparent nylon or polyphthalamide (PPA) variant. This engineered polymer is valued for its exceptional balance of thermal stability, chemical resistance, and mechanical strength, making it a superior alternative to traditional nylons in demanding environments. It is primarily sought by manufacturers in the automotive, electrical & electronics, and industrial components sectors for advanced technical applications.

Application

• Automotive Under-the-Hood Components: Used in connectors, sensor housings, and charge air cooler end caps due to its high heat resistance and strength.
• Electrical Insulation and Connectors: Ideal for miniaturized electronic components, circuit breakers, and LED housings requiring good dielectric properties and dimensional stability.
• Industrial Fluid Handling: Manufactured into pump parts, valve seats, and compressor components that resist corrosion from fuels, oils, and coolants.
• Consumer Appliances: Employed in high-temperature components for kitchen appliances and power tools where clarity and durability are needed.
• Optical and Transparent Parts: Serves as a material for lenses, sight glasses, and protective covers where optical clarity combined with toughness is required.
• Specialty Films and Fibers: Used to produce high-barrier packaging films and high-tenacity fibers for technical textiles.

Quality Control

Our production of this high-performance copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical engineering applications. Quality is verified through a comprehensive suite of tests including intrinsic viscosity, melting point, and thermal analysis (DSC, TGA). Certificates of Analysis (COA) documenting key specifications are provided with every shipment. We support compliance with relevant industry and safety standards such as ISO 9001 and REACH.

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.
