ATH is commonly used in silicone rubber to reinforce the compound and improve the arc tracking and erosion resistance. PORTAFLAME SG10 S8 grade has been carefully designed for use in High Voltage Insulator formulations to further improve:
- Processing (low viscosity and hence lower mixing energy and time)
- Vulcanization (low moisture content, active groups)
- Mechanical and electrical properties due to its easy incorporation and excellent dispersion capabilities
