Epoxy Glass Cloth Laminated Sheets G11(ISO/EPGC3;IEC/EPGC203) / FR5(ISO/EPGC4;IEC/EPGC204) |
¡¡
¡¡
|
¡¡
¡¡
|
Properties and Applications: This two kinds of thermosetting industrial Laminate are electrical alkali-free glass woven fabric base impregnated an epoxy resin binder, G11 is similar to G10 and FR5 to FR4, with the addition of a higher operating temperature and some improved mechanical strength at elevated temperature. It is widely used as all kinds of insulation components. |
