Epoxy Resin Systems for Electric Insulation of High Thermal Conductivity

High thermal conductivity epoxy resin suffers from poor processability and a significant reduction in crack resistance due to high filling. Xrun has adopted a special filling technology to overcome the problem of high thermal conductivity epoxy resin having high filling while experiencing a decline in processability and maintaining good crack resistance.
