BPDA

BPDA BPDA (3,3',4,4'-Biphenyltetracarboxylic dianhydride) is a raw material for the polyimide resin component of one of the super-engineering plastics.  Application S-BPDA can be used to synthesize high molecular weight aromatic polyamide fibers. It can also be used to generate hybrid nanocomposite films. It is used for many important information and electronic technology products such as mobile phones and copying machines.   Details: Chemical Name: 3,3',4,4'-biphenyltetracarboxylic dianhydride Other Name: S-BPDA,BPDA Dianhydride Classification: Anhydride Molecule: C16H6O6 Molecule Weight: 294.22 CAS NO.: 2420-87-3 HS CODE: 2917-3990 Quality Standard: Q/82HL01-2004  Product Specification ITEM INDEX Characteristics White or almost white powder, no bad smell Assay ≥99.8% Melting point(°C) 299.0~302.0 Single metal ion (mg/kg) <1PPM Package 25kg/fiber drum Application Making polymer material,Electronics industry, Chips
