FR4 / G10 Epoxy Glass Laminate Sheet

Epoxy glass laminate (FR4 / G10) offers excellent electrical insulating properties and high mechanical strength, and absorbs very little moisture. Used for insulating parts in switchboards, transformers and electronic equipment.

Material and sizes

EP GC 201/202

FR4 / G10

A glass-fibre-reinforced epoxy laminate; G11 on request. It offers excellent electrical insulating properties and high mechanical strength. It absorbs little moisture, is dimensionally stable and largely retains its insulating properties in humid conditions. FR4 is flame-retardant, while G11 retains its strength better at elevated temperatures. Used for switchgear and transformer insulation parts, motor and generator insulation, test jigs and fixtures.

Frequently asked questions

What is the difference between FR4 and G10?

Both are glass-fibre-reinforced epoxy laminates. FR4 is the flame-retardant version; G10 is not flame-retardant. Their mechanical and electrical properties are similar.

Why can the invoiced weight differ from the calculated weight?

The calculator gives the theoretical weight. The actual weight varies with dimensional tolerances and cutting allowance; we invoice on the actual weight as weighed.

What information should I send for a quote?

We only need the size (thickness × width × length), quantity and delivery location. If you fill in the calculator above, these details are added to the WhatsApp message automatically.
