The insulation grade standards for epoxy resin boards are usually determined based on their electrical insulation performance.
The current common insulation grade standards for epoxy resin boards are as follows:
1. E-grade: (120℃）Thermosetting epoxy resin boards, with poor insulation performance, suitable for low voltage and low
frequency occasions.
2. B-grade:（130℃） Thermosetting epoxy resin boards, with good insulation performance, can be used for
general electrical equipment. Common materials:G10 epoxy sheet，FR4 epoxy sheet
3. F-grade: （155℃）Thermosetting epoxy resin boards, with good insulation performance and strong high temperature resistance,
suitable for high temperature occasions.Common materials:G11 epoxy sheet
4. H-grade: （180℃）Thermosetting epoxy resin boards, with the best insulation performance and high temperature resistance,
suitable for ultra-high temperature occasions.Common materials:EPGC308 epoxy sheet
These standards may vary according to different countries or regions, so it is recommended to select the appropriate epoxy resin board insulation grade according to the specific
usage requirements and relevant standards
