Polyimide adhesives with high temperature resistance
New from Intertronics comes the Polytec PT range of state-of-the-art polyimide adhesives. These polyimide-based chemistries provide excellent thermal resistance, superior to other typical organic adhesives. They are characterised as modified polyimide single-component, solvent-containing adhesives and coatings which are applicable in the temperature range from 240-500degC.
These polyimides are available as electrically conductive, thermally conductive and electrically highly insulating adhesives and coatings, optimised for dispensing, jet-dispensing and stamping techniques. They are also available as screen printable polyimides for the passivation of semiconductor surfaces.
Applications are to be found in the areas of semiconductors, photovoltaics, sensors, fibre optics and general electronics, where their high temperature resistance, electrical conductivity, thermal conductivity and protection against moisture have been found to be highly beneficial. Polytec EC P-690 has been qualified for high-temperature die attach (1.4mm chips) for operating temperatures up to 300degC in an application where evaluation has proved it to have the highest die shear strength of all the polyimide adhesives tested.
The Intertronics range consists of four specific products to suit varying demands of performance and processing - characteristics on which the engineers at Intertronics can advise in relation to customer-specific situations.
