Rigid & insulatingStructural + dielectric

What it is

Epoxy-glass laminate built for strength and insulation.

FRP (Fibreglass Reinforced Plastic) epoxy-glass sheet is a rigid laminate of woven glass cloth impregnated with epoxy resin, cured under heat and pressure. The result is a dense, dimensionally stable panel that combines real mechanical load-bearing strength with reliable electrical insulation.

It machines cleanly — cutting, drilling, tapping and countersinking are all supported — so the same sheet can serve as a structural member and a precision dielectric component in the same assembly.

Why engineers choose it

One material, two jobs: structure + insulation.

High mechanical strength and rigidity under load
Dependable electrical (dielectric) insulation
Good dimensional stability and low creep
Moisture resistance suited to enclosed equipment
Easy to machine — cut, drill, tap and countersink

Grades & Formats

Available grades, made to order

Standard panels plus custom-cut dimensions to your drawing. Tell us the grade, thickness, size and quantity and we’ll confirm material, tolerance and pricing.

FR4

General-purpose epoxy glass

The most widely used grade — balanced mechanical strength and electrical insulation for everyday panels, spacers and structural-dielectric parts.

G10

High-strength structural

Strong, rigid epoxy-glass laminate well suited to mechanically loaded structural insulation components and precision-machined parts.

G11

Higher-temperature grade

Selected where a higher-temperature epoxy-glass grade is required than standard FR4 offers. Tell us your service conditions and we’ll confirm the right grade.

Standard panels & custom-cut to drawing

We supply full panels and custom-cut blanks, with fabrication support including cutting to size, drilling, countersinking and tapping. Thickness, panel size and tolerance are configured to your requirement — share your drawing and we’ll quote it.

Detailed dielectric and thermal specifications vary by grade and thickness. Share your spec requirements and we’ll send the matching datasheet for confirmation.

Typical Applications

Where FRP epoxy-glass is used

Wherever a part needs to carry a load, hold a shape, and insulate at the same time.

Electrical insulation panels

Slot wedges & phase barriers

Mechanical spacers & supports

Arc barriers & creepage parts

Switchgear & power-equipment parts

Structural formers & flanges
