Description
Alicyclic dianhydride CBDA is mainly used as monomer for polyimide film, resins and varnish, especially CPI, Alignment layer monomer, Flexible display, Transparent flexible circuit board, Electronic level CBDA, High transmittance > 89%, Low Yellow Index < 2.0 –> Colorless and High Transparency.
cyclobutane-1,2,3,4-tetracarboxylic dianhydride and diamine monomer are used for preparation a polyimide (PI), the type of polyimide has excellent electrical characteristics and optical type, with the material prepared the PI film, in addition to having a higher rate cast visible outside, and can withstand high temperatures thirty-four Baidu. Its performance is very good, is the preparation of a liquid crystal display with an ideal material for the film.
Reactant for:
Preparation of biologically and pharmacologically active molecules
Preparation of photosensitive polyimide material for high performance organic thin-film transistors
Selective crosslinking of polyimide for photonic devices
