FR4 Epoxy Resin Fiberglass Cloth Laminated Sheet

Serial number
SG-S3800

Product description

laminate insulating glass epoxy sheet— natural color is typically a yellowish Or 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.

Insulation sheet created from electrical glass cloth that has been impregnated with epoxy resin under pressure and heat. With high mechanical strength and electrical properties,thermal-resistance and moisture resistance.

Application

It is used for the insulating spare parts of electrical appliances and transformers.
