INBORD E

Inboard E is a technical laminate from the Isovolta product line, made from epoxy resin reinforced with glass fabric (EP GC 203). It is designed for applications requiring high electrical insulation, mechanical strength, and thermal resistance. It is characterized by excellent dimensional stability, even during long-term operation under demanding conditions. The material is halogen-free and complies with numerous industrial and electrical standards.

Main properties:

• Outstanding electrical insulation at high voltages

• High mechanical strength and rigidity

• Thermal resistance up to 180 °C (Class H)

• Low moisture absorption

• Resistance to chemicals and oils

• Good machinability (cutting, drilling, milling)

• Halogen-free (environmentally friendly)

• Excellent strength-to-weight ratio

Typical applications:

• Insulating components in transformers and generators

• Structural parts in high- and medium-voltage systems

• Support and insulation plates in electric motors

• Electrical barriers and support structures in switchgear

• Industrial automation and power supply systems
