A b r organics limited [abrol] founded in 1991 is the manufacturer of different types of polyimide resins. Abron br 720 fr is an bismaleimide based resin composition which is useful for manufacturing of fr4 grade printed circuit boards which would meet the ul-94 test of flammability. Key features are as follows:
Abron br 720 fr can be used to prepare laminates for the electronics industry by the standard techniques used in the field.
The resin, abron br 720 fr, is dissolved in an solvent and then used to impregnate fabric [glass, silica, etc] and then dried at an elevated temperature to form a prepregs.
The prepregs so obtained may be laminated with copper foil under pressure and temperature.
These laminates can be used in fabrication of printed circuit boards having improved properties [low dielectric constant, improved toughness and excellent thermal resistance].
