RFQ: What is BPDA?
BPDA, full name is 3,3',4,4'-Biphenyl Tetracarboxylic Dianhydride. It is a key monomer for synthesizing high-performance polymers.
RFQ: What are the core features and value of BPDA?
BPDA is a top-tier monomer for manufacturing ultra-high-performance polyimides. Its highly rigid and symmetrical biphenyl structure provides the polymer with exceptional heat resistance, dimensional stability, and mechanical strength.
BPDA is a top-tier monomer for manufacturing ultra-high-performance polyimides, primarily used in the synthesis of polyimide materials with the most demanding performance requirements.
- TOPLUS® BPDA is as a key raw material, used in polymerization reactions with various diamine monomers to synthesize polyimide (PI) materials, particularly for preparing polyimide films, engineering plastics, advanced composite materials, and liquid crystal alignment agents with ultra-high heat resistance, excellent mechanical properties, and dimensional stability. Polyimides made from BPDA (such as the well-known Upilex®-S film) are widely used in high-tech fields such as flexible printed circuit boards (FPCs), microelectronic packaging, aerospace components, high-temperature insulating films, and liquid crystal displays (LCDs) due to their superior performance.
