The global shift toward high-efficiency power systems and precision engineering requires materials that can withstand extreme dielectric stress and mechanical loads. Industrial manufacturers across the aerospace, energy, and electronics sectors increasingly rely on high-pressure laminates to maintain system integrity while reducing weight. In these demanding environments, material selection directly impacts long-term reliability and safety.
WS Hampshire is a premier fabricator and distributor of non-metallic materials, specializing in high-performance thermoset laminates for industrial and power distribution applications. We provide custom-machined solutions that meet the rigorous mechanical and dielectric requirements of modern engineering.

The Properties and Advantages of Ryertex G10
Ryertex G10 is a widely specified rigid electrical insulation material for several functional reasons. This glass-epoxy laminate provides a reliable balance of dielectric strength, mechanical toughness, and dimensional stability. It serves as a cost-effective solution for structural parts that do not require flame-retardant properties.
A primary technical distinction exists between G10 and FR4. While FR4 utilizes brominated epoxy chemistry to achieve a UL 94 V-0 flame rating, G10 is typically a non-brominated material. This difference is critical for systems sensitive to chemical contamination or outgassing.
Common Applications for Ryertex G10
Engineers often select Ryertex G10 when a part must maintain tight tolerances and structural integrity under constant load. It is a preferred choice for the following components:
- Support blocks and spacers. These parts benefit from the material’s high compressive strength.
- Terminal boards and insulating plates. G10 delivers dependable dielectric insulation in moderate environments.
- Cryogenic and vacuum systems. Because it lacks brominated flame retardants, G10 reduces the risk of outgassing in sensitive or tightly enclosed environments.
G10 vs. FR4: Selecting the Right Material
The decision between G10 and FR4 depends on the specific operating environment rather than a “default” choice. While FR4 is necessary when safety regulations mandate flame retardancy, its brominated chemistry can pose risks. Under conditions of extreme heat or electrical arcing, the bromine in FR4 can generate hydrogen bromide smoke. This byproduct is potentially corrosive to copper, stainless steel, and other metallic system components.
If your application involves high-temperature cycles or requires a higher performance margin, materials such as Ryertex G11 or Ryertex FR5 may be more suitable. NASA’s guidance on outgassing emphasizes that designers should verify material suitability through testing rather than relying on the grade name alone.
