Description

1,4-Benzenedicarboxylic Acid Polymer With [1,1'-Biphenyl]-4,4'-Diol, 4-Hydroxybenzoic Acid And 6-Hydroxy-2-Naphthalenecarboxylic Acid is a high-performance, fully aromatic thermotropic liquid crystalline polymer (LCP) known for its exceptional thermal stability, mechanical strength, and chemical resistance. This material matters for engineers and formulators seeking to enhance the performance and durability of demanding components under extreme conditions. It is primarily needed by the electronics, automotive, aerospace, and industrial sectors for advanced molding applications where precision, reliability, and resistance to heat and aggressive chemicals are critical.

Application

• High-Precision Electronic Components: Used in connectors, sockets, bobbins, and chip carriers for surface-mount technology (SMT) due to its excellent dimensional stability and low coefficient of thermal expansion.
• Under-the-Hood Automotive Parts: Ideal for sensors, ignition components, transmission system parts, and fuel system components that must withstand high temperatures and exposure to fuels and lubricants.
• Aerospace and Defense Hardware: Employed in housings, brackets, and structural components requiring a high strength-to-weight ratio and flame retardancy.
• Chemical Processing Equipment: Suitable for pump components, valve seats, and seals that demand outstanding resistance to strong acids, bases, and organic solvents.
• Miniature and Micro-Molded Parts: Excellent flow characteristics allow for the molding of intricate, thin-walled parts with high precision and minimal warpage.
• High-Frequency Circuit Boards: Used as a substrate material for its stable dielectric properties across a wide temperature and frequency range.

Quality Control

Our Liquid Crystal Polymer (LCP) is manufactured under stringent process controls to ensure batch-to-batch consistency and performance reliability. Quality is verified through a comprehensive suite of tests including intrinsic viscosity (IV), melt viscosity, thermal analysis (DSC, TGA), and mechanical property evaluation. While not a pharmaceutical ingredient, production adheres to ISO 9001 quality management principles. A detailed Certificate of Analysis (COA) providing lot-specific data on key parameters is available with every shipment.

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). Keep the original packaging sealed until use to prevent moisture absorption. This polymer is stable under these conditions but should be stored away from strong oxidizing agents.
