Epoxy Glass Sheet is manufactured using electronic-grade alkali-free fiberglass fabric impregnated with epoxy resin and other modified materials, followed by high-temperature and high-pressure lamination. Epoxy Glass Sheets feature excellent electrical insulation, flame retardancy, high temperature resistance, and strong mechanical performance.
FR-4, which we commonly refer to in the PCB industry, is not actually a specific material name. It is a flame-retardant grade designation.
Phenolic Cotton Cloth Laminate is manufactured by impregnating cotton fabric with phenolic resin, followed by curing under heat and pressure. It is classified as a Thermal Class E insulating material and provides excellent mechanical properties, oil resistance, and reliable dielectric performance.
Epoxy Sheets are widely used in electrical and electronic applications due to their excellent combination of heat resistance, corrosion resistance, wear resistance, light weight, and electrical insulation properties.
Bakelite sheet, also known as Phenolic Paper Laminated Sheet, is manufactured using high-quality bleached wood pulp paper and cotton linter paper as reinforcing materials. These substrates are impregnated with phenolic resin produced from high-purity synthetic petrochemical raw materials and then processed through heat and pressure lamination.
Electrical resistance is the reciprocal of conductance, and resistivity refers to the resistance per unit volume of a material. The lower the conductivity of a material, the higher its resistance. For Electrical Insulation Materials, higher resistivity is always preferred. A higher resistivity indicates better insulation performance and lower leakage current under electrical stress.
If you're struggling to choose among various electrical insulation materials, this guide compares five commonly used laminated insulation sheets: 3240 epoxy sheet, FR4 Fiberglass Sheet, Bakelite Sheet, Phenolic Cotton Cloth Laminate, and Phenolic paper laminate, helping you quickly identify the most suitable material for your application.
Is your microwave oven suddenly failing to work? Are high-temperature industrial machines experiencing frequent breakdowns? In many cases, the problem may be traced back to a critical component—the mica board.
In today’s electronic era, electronic products are deeply integrated into our daily lives and are evolving at a rapid pace. It is difficult to imagine modern life without them. Epoxy glass sheets are a key insulating material widely used in electronic products. There are many types, including FR-4 Epoxy Glass Sheet, 3240 Epoxy Sheet, G11 Epoxy Glass Sheet, and G10 Epoxy Glass Sheet, each designed to meet different application requirements. Among them, G11 Epoxy Glass Sheet is considered one of the higher-performance materials, and it is important to understand its characteristics before use.
