Epoxy
Epoxy molding materials exhibit very low viscosity when filling a mold and therefore offer the designer flexibility in encapsulating sensitive electronic components and in forming high-density pin connectors. Sumitomo Bakelite North America's Epoxy materials retain a high percentage of their properties.
Key Properties:
Thermal
  • Glass transition temperatures of 155°C - 175°C
  • Resistance to thermal shock
  • Low outgassing in high vacuum
Electrical
  • High insulation resistance even after long exposure to high temperature and humidity
  • Low dielectric loss
  • High arc resistance, even under adverse conditions
Chemical
  • Highly resistant to many solvents, degreasing compounds and plating baths
Corrosion Resistance
  • Unaffected by sea water
  • Noncorrosive to metal inserts
  • Compatible with magnet wire (used with coil bobbins) as epoxy does not outgas elements that can attack the insulation
