Let's first understand the characteristics of 3240 epoxy board

It is made of electric glass cloth and epoxy resin by drying and hot pressing. There are no bubbles, pits and wrinkles on the panel. It has excellent mechanical properties, excellent mechanical properties, arc resistance, specifications and other characteristics. For example, at the temperature of the medium, it can give full play to its mechanical properties; under a high temperature environment, it can give full play to its electrical properties. Therefore, due to these characteristics of epoxy boards, epoxy boards are very suitable for high-insulation structural parts in the electrical and electronic fields. But its processing material is halogen-containing. The halogen element here means fluorine, chlorine, bromine, iodine and ah. They can play a flame-retardant effect, but they are toxic. If burned, they will release harmful gases such as dioxins and benzofurans. They also have a strong smell of smoke, which is easy to cause cancer and is extremely harmful. Therefore, the use of halogen-free epoxy boards is now advocated. Therefore, its materials are not environmentally friendly and have certain hazards to the environment and the human body, especially when it burns, it will produce a lot of smoke. Does not meet the environmental protection requirements set by the state. But the price is relatively cheap.

What are the characteristics of FR4 epoxy board?

FR4 is usually water green. It is a plate-like laminated product made of special electronic cloth, epoxy resin and other materials through high temperature and high pressure hot pressing. Compared with 3240, it has the advantages of high temperature resistance (Class B), insulation, dielectric, flame retardant (in accordance with 94V-0 standard), moisture resistance, good toughness, smooth surface, no pits and thickness tolerances. Suitable for high-performance electronic insulation products. Even today's high-speed trains and high-speed trains use this kind of insulating material. It can be simply understood that FR4 is an upgraded version of 3240.

What are the characteristics of G11 epoxy board?

G11 epoxy board is the best one among the three models. At present, the thermal stress in epoxy resin board is relatively high, as high as 288°C. Its heat resistance value is as high as 160-180 degrees, especially the low water absorption rate (water absorption rate is almost 0, after 24 hours, the water absorption rate is only: 0.09%), it is the best choice for high-voltage switchgear and high-end electrical and electronic products. But the price is naturally higher than the first two models.

It has high mechanical and dielectric properties, good heat resistance and moisture resistance, and good processing properties. Used in plastic abrasives, injection molding abrasives, machinery manufacturing, molding machines, drilling machines, injection molding machines, motors, printed circuit board fixtures, and table polishing pads.
