Features and Benefits

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
