Black/Yellow/Green FR4 Epoxy Glass Laminated Sheet 

                                                       Black/Yellow/Green Insulating FR4 Epoxy Material Plate Epoxy Glass Cloth FR4 sheet ,Grade FR4 sheet exhibits extremely high mechanical strength(flexural,impact,and bonding) at room temperature and has good dielectric loss and electric strength properties under both dry and humid conditions.  Grade FR5 sheet exhibits good chemical resistance and its heat resistance is better than FR-4,material is intended for use as electrical and electronic insulation whrer low moisture absorption and high physical strength is needed,it is not recommended for wear applications. Epoxies are thermosetting polymer resins where the resin molecule contains one or more epoxide groups. The chemistry can&n…
