G10 and FR4 Glass-Cloth Reinforced Epoxy TUBE -is natural color is typically a yellow to light green. 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
G10/FR4 tube has extremely high mechanical strength, good dielectric loss properties,
good electric strength properties, both wet and dry.
FR4 TUBE used as insulating part in machinery and electrical instruments, it also can be used as pressure ,usually used in the transformer
Size : according to customer design
Longth :500mm or 1000mm also can cut according to customer requirements
