G10 Epoxy Sheet
Description
A brand name for a composition material of glass fiber and resin lamination. “G” stands for glass fiber “10” mean that glass fiber is accounting for 10% of it. G10 material has the features of insulation, wear resistance and corrosion resistance well. Compared with ordinary glass fiber sheets, the epoxy laminations provides increased tensile strength, elastic modulus, impact resistance, chemical stability, fatigue resistance, temperature resistance and electrical insulation.
G10 and FR4 glass cloth reinforced epoxy natural is typically a yellowish to light green color. The most versatile all-around laminate grades are continuous glass woven fabric impregnated with an epoxy resin binder. Epoxy resins are among the most versatile and widely used plastics in the electronics field, primarily because water absorption is virtually nil, rendering it an outstanding insulator. Beyond its electrical insulating properties, epoxy resins exhibit great dimensional stability (shrinkage is usually less than 1 percent) and superior adhesive properties. G10/FR4 has extremely high mechanical strength, good dielectric loss properties, and good electric strength properties, both wet and dry.
Options:
- G10: 10% glass fiber; properties listed below
- G10 FR4: fire retardant grade of G10
