Product Description

Fr4 Laminated Fiberglass Insulation is commonly known as FR-4 epoxy sheet, and its classification is very wide. The main models are:

G11: Flame retardant grade UL94V0, the electrical performance is still very good in dry and wet states, and it is a good choice for high-end electrical insulation parts.

G10: Flame retardant grade UL94V2, the electrical performance is still very good in dry and wet states, making it a good choice for high-end electrical insulation parts.
