Alumina Filler for Electrical Parts

About the product

FA

As filling material for epoxy resin cast articles used as electrical parts, we provide alumina filler materials corresponding to each formulation (pot life). We are working to offer stable quality under a controlled environment and meet customers’ demands.

Characteristics

  1. 1. Filling this product into epoxy resin can add chemical corrosion resistance, heat raddiation performance, electrical insulation performance, mechanical strength, dimensional stability, etc.
  2. 2. Excellent in filling density and workability.
  3. 3. Minimizes iron and foreign materials.
  4. 4. With grades of different reactivity (pot life) provided, selection is available depending on the resin (hardening agent) type.

Application example

  1. 1. Various kinds of epoxy resin cast articles
  2. 2. Resin insulator for SF6 gas circuit breaker
  3. 3. Sealant for electronic parts
  4. 4. Epoxy coating
