Description

1,4-Benzenedicarbonyl Dichloride, Polymer With 1,4-Benzenediamine is a high-performance polyamide polymer, specifically a poly(p-phenylene terephthalamide) (PPTA) type material. This polymer is valued for its exceptional thermal stability, chemical resistance, and outstanding mechanical strength-to-weight ratio. It is a critical material for manufacturers in the advanced materials, aerospace, and industrial filtration sectors seeking durable, high-performance components.

Application

• High-Strength Synthetic Fibers: Primary raw material for the production of para-aramid fibers (e.g., Kevlar®-type fibers) used in ballistic armor, cut-resistant gloves, and protective clothing.
• Advanced Composites: Reinforcement agent in high-performance composites for aerospace components, automotive racing parts, and sporting goods.
• Industrial Filtration: Manufacture of high-temperature and chemically resistant filter fabrics for hot gas filtration and demanding industrial processes.
• Optical and Electrical Materials: Used in the production of liquid crystal polymers (LCPs) for precision electronic components, connectors, and fiber optics.
• Asbestos Replacement: Key component in high-temperature gaskets, seals, and brake linings as a safer, high-performance alternative.
• Ropes and Cables: Production of lightweight, high-tensile strength cables for marine, lifting, and suspension bridge applications.

Quality Control

Our polymer is produced under strict quality management systems to ensure batch-to-batch consistency for critical applications. Quality is verified through parameters including inherent viscosity, thermal stability (TGA), and chemical composition. A comprehensive Certificate of Analysis (COA) detailing specific lot characteristics is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids, bases, and moisture. For long-term storage, consider an inert atmosphere to preserve polymer properties.
