GPO-3 Insulation Sheet is a rigid sheet insulating material manufactured by impregnating non-alkali glass fiber mat with unsaturated polyester resin paste together with corresponding additives, followed by hot pressing. It refers to unsaturated polyester glass fiber mat sheet material for mechanical and electrical purposes. It delivers excellent electrical properties under high humidity, favorable mechanical performance at medium temperatures, inherent flame retardancy, as well as outstanding arc resistance and tracking resistance.

FR4 Sheet, also known as epoxy fiberglass sheet or flame retardant insulation board, is fabricated by impregnating fiberglass woven cloth with flame-retardant epoxy resin and hot-pressed under high temperature and pressure. It is widely utilized in high-end precision equipment that demands high safety and reliability standards.

FR4 fiberglass sheet is an insulation plate formed by hot pressing after impregnating woven fiberglass cloth with epoxy resin. It boasts excellent insulation performance, high mechanical strength and great temperature resistance, along with antistatic and flame-retardant features. Thanks to its comprehensive properties, it maintains stable dielectric performance in both dry and humid environments, making it one of the indispensable materials for photovoltaic power generation equipment.

Epoxy Glass Sheet boasts outstanding comprehensive performance, featuring high temperature resistance, corrosion resistance, high mechanical strength, superior machinability, low water absorption, reliable insulation and excellent electrical properties. There are various types of Epoxy Glass Sheet available, including 3240, G11, FR-4, G10 and so on.
