Description
99.7% Alumina Filler TM-FA | High-Voltage Electrical Insulation | 1.20 g/cm³ Density
Product Overview
TM-FA is a specialized high-purity alumina (Al₂O₃ ≥99.7%) powder engineered as a functional filler for epoxy casting systems in high-voltage electrical equipment. It is designed to enhance the mechanical and insulating properties of insulation components used in SF6 gas-insulated switchgear (GIS) and other high-voltage applications.
Key Properties & Benefits
  • Superior Electrical Insulation: Ensures high dielectric strength and reliable performance in demanding high-voltage environments
  • Enhanced Mechanical Strength: Contributes to the structural integrity and durability of cast epoxy insulation parts
  • Optimized Rheology: Carefully controlled particle size distribution and morphology ensure ideal viscosity (400-700 cP) for seamless processing and high packing volume during casting
  • High Purity & Reliability: Ultra-low impurity content guarantees consistent performance and long-term stability
