3240 epoxy fiberglass laminate sheet  is a commonly used thermosetting laminated insulation material, made from alkali-free electrical glass fiber fabric impregnated with epoxy resin and cured under high temperature and pressure. It is widely applied in electrical insulation and mechanical structural fields, and is considered a medium-to-high performance insulating material.

3240 epoxy sheet Key Features

Excellent electrical insulation performance: Maintains stable dielectric properties under both dry and moderately humid conditions

High mechanical strength: Good compressive and flexural strength, suitable for structural support components

Good heat resistance: Thermal class B (130°C)

Moisture resistance and dimensional stability: Minimal performance degradation in humid environments

Application of 3240 epoxy sheet

Insulation structural parts for motors and generators (such as slot wedges and spacers)

Insulating support components for transformers

Internal insulation parts in high- and low-voltage switchgear

Insulating plates and terminal boards in electrical equipment

Structural insulation components in industrial machinery
