Yellow epoxy board usually refers to the 3240 epoxy board, which is a widely used insulating material. The following is the relevant introduction: **Properties**: - Excellent Electrical Insulation Performance: Made of glass fiber cloth and epoxy resin, it has good dielectric properties. It can effectively block the flow of current, prevent leakage and short circuits, and maintain stable insulation performance in high-voltage environments. - High Mechanical Strength: It has high tensile, bending and impact strength. It can withstand a certain amount of pressure and external force, and is not easy to deform or be damaged. It can be used to manufacture insulating structural components that bear mechanical stress. - Good Chemical Resistance: Epoxy resin has strong chemical corrosion resistance and can resist the erosion of most acids, alkalis, solvents and salts. It can maintain stable physical and electrical properties in harsh chemical environments. - Good Heat Resistance: The temperature resistance grade is Class F (155°C). It can still maintain good mechanical and electrical properties at high temperatures and can be used in a certain high-temperature environment. **Appearance**: The surface should be smooth, free of bubbles, wrinkles and cracks. Other defects such as scratches, dents and uneven color should be minimized, and a small number of color spots are allowed. **Specifications**: The thickness generally ranges from 0.5mm to 100mm. Conventional specifications include 1000mm×2000mm, 1220mm×2440mm, etc.
