Epoxy resin boards, also known as insulating boards, epoxy boards, or 3240 epoxy boards, are characterized by their strong adhesion and shrinkage resistance. They are suitable for high-insulation structural components used in mechanical, electrical, and electronic applications, offering high mechanical and dielectric properties, as well as good heat and moisture resistance.

Customers often inquire about the grading of epoxy resin insulated rubber boards. Jineng's Sales Manager, with his professional technical knowledge as an epoxy board manufacturer, provides a detailed explanation to the customers. Generally, the grades mentioned by customers, such as B, F, H, etc., actually refer to the heat resistance temperature grades of the insulating material.

Epoxy boards are an insulating material, and their insulating properties are closely related to temperature; the higher the temperature, the poorer the insulating performance of the epoxy board. To ensure insulating strength, each insulating material has an appropriate working temperature range. This requires that we control an appropriate temperature when using insulating plates, which is also a good way to maintain the plates. Because at high temperatures, not only does the insulating performance of the plate deteriorate, but the plate also ages rapidly. The relationship between the temperature and insulating temperature grade of epoxy resin insulating plates: insulating materials are classified into grades Y, A, E, B, F, H, and C according to their heat resistance. For example, the working temperature range for grade A insulating materials is 105°C. Generally, the insulating materials used in distribution transformers and motors, such as epoxy resin insulating rubber plates, mostly belong to grade A. Insulating temperature grades: Grade A - 105°C, Grade E - 120°C, Grade B - 130°C, Grade F - 155°C, Grade H - 180°C. Winding temperature rise limit (K): 60, 75, 80, 100, 125. Performance reference temperature (°C): 80, 95, 100, 120, 145.
