What is the difference between epoxy board 3240 and G10 epoxy board?

In our insulation material industry, there are many types of epoxy boards, each of which has unique properties and meets the requirements of different industries, such as G10, G11, 3240, FR-4.7628.2116.1080, etc. Since they are all insulation materials, what is the difference? First of all, let’s focus on analyzing the difference between 3240 and FR-4.

First of all, you need to know that the 3 in 3240 epoxy board represents laminated products, which are also said to be pressed from multiple layers of cloth. 2 represents inorganic substrate board, 4 represents its maximum operating temperature of 155 degrees, and its heat resistance grade belongs to Class B, and 0 represents the code of the product type. Therefore, the full name of 3240 epoxy board is epoxy laminated glass cloth board. It is widely used in the manufacture of electrical and mechanical insulation parts, with average performance, and belongs to domestic epoxy board.

The G in G10 is the abbreviation of glass fiber in English, and the number 10 represents the content of glass fiber at 10%. G10 is synthesized by imported electronic grade glass fiber cloth and imported epoxy resin, with high process and superior performance. Flame retardant grade UL94-VO, can withstand high temperature of 180 degrees, can withstand high temperature of 288 degrees for a short time, good mechanical properties at high temperature, with certain strength, acid and alkali resistance, waterproof and good insulation performance.

As a common electrical insulation part manufacturing, the use of 3240 epoxy board can basically meet the common electrical insulators in life. G10 epoxy board meets certain requirements for insulation performance, electrical equipment with higher temperature resistance, etc. Obviously, the performance of G10 epoxy board exceeds that of 3240 epoxy board.

GOP-3 unsaturated polyester glass felt laminated board

The board is a hard plate-shaped insulating material made of alkali-free glass fiber felt impregnated with unsaturated polyester resin paste, and added with corresponding additives and hot pressed. The product has good electrical properties, good mechanical properties at medium temperatures, flame retardancy, and good arc resistance and resistance to leakage traces. Compared with other laminate materials, GPO-3 has excellent arc resistance (>180s) and resistance to leakage traces (CTI600V); the heat resistance grade reaches F grade (>160℃), and it can work stably in a continuously rising temperature environment and maintain good electrical and mechanical properties. It has the characteristics of high mechanization, automation, stable product quality, and low cost; it is widely used in motors
