What Electrical Epoxy Resin Actually Is Electrical epoxy resin is a two-component thermosetting polymer system formulated specifically to insulate, protect, and mechanically stabilize electrical and electronic components. Once a resin base is combined with a hardener, the mixture cures into a rigid...
Epoxy Insulating Glue Is the Preferred Choice for Electronics Protection For protecting sensitive electronic assemblies from electrical shorts, moisture, and mechanical stress, epoxy insulating glue offers the most reliable and versatile solution. Its combination of high dielectric strength, stron...
Executive Summary: The Direct Answer The best high thermal conductivity epoxy resin is selected by matching thermal conductivity (≥2.0 W/m·K) with viscosity (<50,000 cP) and glass transition temperature (Tg ≥ 120°C) for your specific application, while verifying the filler type (boron nitride vs...

To date, Xrun has supplied over 180 thousand tons of epoxy materials for electrical insulation, supporting ultra/extra-high voltage GIS, GIL, dry-type transformers, and cable accessories.
Epoxy resin additives and auxiliary materials play a critical role in enhancing the performance, reliability, and processability of epoxy systems in industrial applications. Their functions can be categorized as follows:
| Type of Additive / Auxiliary Material | Main Function | Performance Impact | Application Example |
| Accelerators | Reduce curing time | Faster production cycles, improved efficiency | GIS insulation casting |
| Thixotropic Agents | Control resin viscosity and prevent sagging | Better mold filling, consistent insulation thickness | Dry-type transformer epoxy molding |
| Coupling Agents | Enhance adhesion between epoxy resin and fillers | Improved mechanical strength, long-term reliability | Cable accessories, insulating bushings |
| Fillers & Extenders | Adjust thermal conductivity and reduce shrinkage | Improved heat dissipation and dimensional stability | GIL & GIS insulation |
| Flame Retardants | Improve fire resistance | Safety compliance, reduced flammability | Electrical insulation for switchgear |
