Description and Uses

Biphenyl-4,4′-dicarboxylic acid (BPDC) belongs to the class of monomers known as aromatic dicarboxylic acids. It is used to prepare BPDC-based polymers, which exhibit excellent thermal stability, making them suitable for applications where high-temperature resistance is required. These polymers also demonstrate high electrical insulation properties due to their low dielectric constant and high breakdown strength. They find applications in the electrical and electronics industry for insulation, encapsulation, and fabrication of high-performance electronic devices.
