Among all types of epoxy board, FR-4 is the most widely used one. Its raw material is epoxy resin, glass fiber and flame retardant. It complies with safety standard UL94V-0. Even if the temperature is too high, it will burn and leave. After the fire source will also go out on its own. FR-4 epoxy board can be subdivided into halogen and non-halogen, halogen is green, halogen-free is yellow, this article Xiaobian tell everyone about the green FR-4 epoxy board.
Green epoxy board performance is good, it is resistant to high temperature 120 degrees Celsius, a short time can work at 130 degrees Celsius temperature, low water absorption, almost zero. For chemical substances such as acids, alkalis, salts, alcohols, etc., it also has a certain resistance to corrosion, and can be used in dry, hot, humid, and cold environments. It also has its drawbacks. Although the added halogen elements such as fluorine, chlorine, bromine, iodine, and thorium can be flame-retarded, combustion can release toxic substances. However, when it is used, there is no need to worry too much. As long as the temperature is stable within the range of use, it will not burn. Its price is much cheaper than the halogen-free epoxy board and is suitable for use in developing countries.
FR-4 is a relatively early epoxy board model, G-10 is based on its development, compared with FR-4, G10 lack of self-extinguishing characteristics. Aqua Green FR-4 epoxy board can be used as insulation components of transformer skeletons, switches, printed circuit boards, and other electrical appliances. It is widely used.
Ztelec’s green FR-4 epoxy board is pressed by the most advanced machine, uniform thickness, small tolerances, smooth surface, size can be customized according to customer requirements. Other types of epoxy board we also have, the same excellent quality.
