The difference between epoxy insulation board G10 and FR4

The difference between epoxy insulation board G10 and FR4

Both G10 and FR4 are composite materials made of glass fiber cloth and epoxy resin. Due to different production processes, the corresponding uses are also different. Many people confuse the G10 insulation board with the FR4 insulation board, which is wrong. Let's take you to understand the difference between the epoxy insulation board G10 and FR4.

G10 insulation board, where "G" means the abbreviation of Glass Fiber (Chinese meaning: glass fiber). "10" usually refers to the percentage of glass fiber in the G10 sheet, which is initially 10%.

As a new type of composite material, G10 insulating board has a wide range of uses. The tool components processed by G10 insulating board have the characteristics of insulation, acid and alkali corrosion resistance, wear resistance, etc., and the processed products will not be affected by water vapor. Penetration of liquids such as oil. The density of the G10 insulating board is low, and the processed product is light and light. At the same time, the hardness of the G10 insulating board is very high. Many times, G10 materials are used in aviation. In addition, in our daily life, we are likely to come into contact with G10 materials at any time, such as more and more The handles on more knives are made of G10 material.

G10 insulation panels are available in green, black, yellow, and special custom colors such as red and blue.

FR4 is the general term for this type of board. Different places call it differently. Some are called FR4 epoxy board, some are called FR4 insulation board, and some places FR4 means glass fiber cloth reinforcement board. No matter how you call it, FR4 refers to a new type of composite material that is combined and pressed by glass fiber cloth and resin.

FR4 insulation board has stable electrical insulation performance, flat and smooth board surface, uniform board size, standard industry specification parameters, and uniform thickness tolerance standards. It is suitable for products required by the modern high-performance electronic insulation industry, and is also suitable for large-scale batch production. Production, FR4 insulation board has high mechanical properties and dielectric properties, good heat resistance and moisture resistance and good machinability, uniform size parameters make it widely used. Whether it is high-speed rail motor insulation parts or precision electronics industry planetary wheels, FR4 insulation boards can do it.

The colors of FR4 epoxy boards are green, yellow, black, and white, and there are also some customized colors, such as red, blue and pink.

In recent years, the application market of FR4 epoxy board is getting bigger and bigger. Many manufacturers are developing new FR4 insulating boards. Improvements in production technology can make FR4 insulating boards anti-static on one or both sides. , which makes the application market of FR4 epoxy board more extensive.

Whether it is G10 insulation board or FR4 insulation board, they are all new composite materials. They have natural advantages over traditional materials in terms of environmental protection and economic cost. They have replaced traditional materials in more and more fields. The world's increasingly technological future plays an important role.
