LaRC-SI (Langley Research Center - Soluble Imide) is an
amorphous thermoplastic. It was developed by Dr. Robert G. Bryant, a chemical engineer at NASA Langley Research Center. The LaRC-SI can be used as a dielectricfor thin film sensors, as an adhesiveto place diamonds on surfaces to increase thermal conductivity, and as an intermediate layer to allow the placement of metal on aluminium nitride.
As an amorphous thermoplastic, the LaRC-SI can be reformed at elevated temperature and pressures. It can be applied in the form of a spray, spin, dip coating, paint, or spread with a doctor's blade. The LaRC-SI has excellent adhesive and dielectric properties. It can also be recycled.
Potential applications for this material are
resinfor mechanical parts such as gears, bearings and valves, advanced composites like carbon fiber, high strength adhesives, thin film circuits, and as a dielectric film for placing electrical components on conductive materials.
