G10 Fiberglass Density Standard

The density of G10 fiberglass (G10 epoxy laminate) follows well-established industry standards, mainly based on NEMA and IEC specifications.

G10 epoxy fiberglass sheets in different colors

1.Standard Density Range of G10 Fiberglass

Typical density range:1.70 – 1.90 g/cm³ (≈ 1700 – 1900 kg/m³)
This is the most widely accepted density range for G10 fiberglass in the global market.

2. Typical Density Under Different Standards

NEMA G-10 (American Standard)

Typical density:1.75 – 1.85 g/cm³
Manufactured from woven fiberglass cloth impregnated with epoxy resin and hot-pressed
This density range indicates:Proper fiberglass-to-resin ratio,Excellent balance between mechanical strength and electrical insulation performance
Most G10 materials used for electrical and industrial applications exported to North America fall within this range.

IEC 60893 (European Standard, EP GC 201 / 202)

Typical density:1.70 – 1.90 g/cm³
Density variation depends on:Fiberglass content,Resin system,Pressing pressure and manufacturing process

3. What Does Density Difference Mean? (Very Important)

Higher density is not always better. High-quality G10 typically falls within 1.78 – 1.85 g/cm³.

4. Density Comparison with Similar Materials

5. Professional Wording for Procurement & Technical Documents

Example expressions:Density: 1.80 ± 0.05 g/cm³ (according to NEMA G-10) or Typical Density: 1.75 – 1.85 g/cm³
