PE6873 BTDA Powder (CAS No. 2421-28-5)

BTDA Powder Description

BTDA (3,3′,4,4′-Benzophenonetetracarboxylic Dianhydride) Powder is a high-purity organic dianhydride widely used as a key raw material in the synthesis of high-performance polyimides. Known for its excellent thermal stability, chemical resistance, and mechanical strength, BTDA enables the production of polymers that perform reliably in demanding environments. It is particularly suitable for applications in aerospace, electronics, and automotive industries where high-temperature resistance (up to 300°C), dimensional stability, and strong adhesion to various substrates are essential.

BTDA Powder Applications

·       High-Performance Polyimides: Used as a key dianhydride monomer in the synthesis of thermally stable polyimide resins and films.

·       Electronics & Semiconductors: Ideal for insulating materials, flexible printed circuit boards (FPCBs), and photoresist formulations.

·       Aerospace & Automotive: Employed in composites and coatings that require excellent heat resistance and mechanical strength.

·       Adhesives & Sealants: Provides strong bonding performance to substrates like metals, glass, and ceramics.

·       Membrane Materials: Utilized in gas separation and filtration membranes due to its stable molecular structure.
