The nature and use of various types of epoxy board products in insulating materials

Epoxy boards contain flame retardant materials, so it is also an mica tape for cable, a lot of this type of material, can be distinguished according to different basis, but the same is their performance, high temperature, corrosion resistance, high Toughness, high strength, high mechanical processing and so on.
Epoxy board can be divided into water green, water blue, black, yellow, white; or by chemical composition can be divided into halogen epoxy plate and halogen-free epoxy board; can also be divided into flame retardant epoxy Board and non-flame retardant epoxy board two categories.
To G11 epoxy board, it is a hard mica cable tape, its heat resistance and water resistance are very good, glass transition temperature of 175 degrees Celsius, can be used in humid environments. Therefore, such a plate is mainly used to manufacture high-voltage switch.
There is also a water green G10 epoxy board, which is made by dipping the alkali-free glass fiber cloth with epoxy resin. Since the alkali-free glass fiber cloth is a material containing no halogen element, it does not cause environmental Pollution, switchgear, transformers, explosion-proof electrical appliances are made of this insulating material.
Compared to the price of 3240 epoxy board cheaper, such acetate cloth tapes are generally used in low-grade, mid-range electrical products. In addition, there is a special electronic parts and epoxy phenolic resin and other materials made of hot FR-4 epoxy board, mainly used to manufacture insulation pads, transformer insulation board, grinding gears and so on.
