Molding Compounds for Electrical and Electronics Applications

Hexion’s thermosetting molding compounds are utilized in a variety of electronic applications when there must be a combination of:

  • Good electrical insulating properties and high heat resistance
  • Rigidity
  • Surface hardness
  • High elastic modulus and
  • Good solvent resistance.

Even if the recommended operating temperature range is temporarily exceeded, dimensional stability will be maintained with Hexion's molding compounds.

Specific applications for our molding compounds include:

  • LS and FI switches
  • Performance and motor safety switches
  • Energy regulators, relays, thermostats
  • Electromagnetic coils and coil forms
  • Electric and gas meters
  • Lamp sockets
