The 3240 Epoxy Sheet, also known as 3240 epoxy phenolic glass cloth laminated sheet, is a widely used insulation material recognized by its typical yellow appearance. Its price varies significantly depending on the grade, manufacturing standard, and sheet thickness.

Market Price Overview
Based on market standards, 3240 Epoxy Sheets are generally available in National Standard Grade (GB), Grade A, and Grade B. Each grade differs in performance, appearance, and cost. Below is a detailed comparison.
National Standard (GB) 3240 Epoxy Sheet
This grade has strict material and performance requirements; therefore, it is used less frequently and priced higher.
0.5 mm thickness: about 6–7 USD/kg
1.0–1.5 mm thickness: about 6–7 USD/kg
2 mm thickness: about 5–6 USD/kg
3.0–55 mm thickness: about 5–6 USD/kg
Grade A 3240 Epoxy Sheet
Grade A is the most commonly used material in the industry and offers a good balance between price and performance.
0.5 mm thickness: about 4 USD/kg
1.0–1.5 mm thickness: about 4 USD/kg
2 mm thickness: 3–4 USD/kg
3.0–55 mm thickness: about 3–4 USD/kg
Grade B 3240 Epoxy Sheet
Grade B is more affordable but may vary in appearance and performance. Because of the lower price, buyers should verify the material to avoid misidentification.
0.5 mm thickness: about 3 USD/kg
1.0–1.5 mm thickness: about 2–3 USD/kg
2 mm thickness: 2–3 USD/kg
3.0–55 mm thickness: 1–2 USD/kg
Application Recommendations
When selecting 3240 Epoxy Sheets, buyers should consider both project requirements and budget.
GB National Standard sheets are ideal for applications with strict mechanical and electrical insulation requirements.
Grade A sheets are suitable for most industrial uses, including mechanical parts, insulation components, and general processing.
Grade B sheets are recommended for cost-sensitive applications where basic insulation is sufficient.
Understanding the specifications, grade differences, and performance features can help buyers make smarter purchasing decisions.
