What is FR-4/G10?

FR-4 and G10 are glass epoxy laminates that have become the gold standard in industrial and electronic applications. FR-4 incorporates flame-retardant properties, making it ideal for environments where safety is critical, while G10 is a versatile alternative for applications that do not require flame resistance.

Both materials are thermosetting composites, offering excellent dimensional stability and resistance to moisture, heat, and chemicals. This makes them indispensable for creating components that must perform under high stress, whether mechanical, thermal, or electrical.
