GPO-3 board, also known as GPO-3 laminated sheet or UPGM-203, is a high-performance insulating material. GPO-3 board is made of alkali-free glass fiber felt plate immersed in unsaturated polyester resin paste, and then added the corresponding additives, and then hot pressed to form a hard plate like insulation material.

GPO-3 board Color and specifications: GPO-3 board is usually white, brown red or other colors, its specifications are varied, common thickness range between 0.8mm and 100mm, size including 914×1828mm, 1220×2440mm and other standard sizes, but also can be customized according to customer needs.

GPO-3 board Characteristic

1.Electrical performance: The GPO-3 board has the characteristics of good electrical performance under high humidity, arc resistance and leakage trace resistance, and its leakage resistance index can reach 600V.
2.Mechanical properties: At moderate temperatures, GPO-3 boards show good mechanical properties. The high-strength glass fiber reinforced polyester laminate material does not shatter and provides structural support.
3.Flame retardant performance: GPO-3 board is flame retardant, and the smoke and toxic smoke are very small when burning (especially Grade UTR grade materials do not contain halogens).
4.Machinability: These materials can be easily formed using standard metal handling equipment and can be pressed, drilled, machined, cut and frosted.

GPO-3 board Application

Electrical switches and circuit breakers:
In electrical switches and circuit breakers, GPO-3 boards are often used as safety baffles, safety shields, and spacer liners. Its good electrical insulation and flame retardant properties make it ideal for these critical components.
Motors and motors:
In the manufacture of motors, GPO-3 boards are used as armature components, movable plates, slot-wedge stators, stationary gaskets, thin gaskets, and carbon brush holders. These components need to withstand the mechanical and electrical stresses of the motor, and the strength and insulation properties of the GPO-3 board enable it to meet these requirements.
Power distribution system:
In power distribution systems, GPO-3 boards are often used as insulation materials for busbars. Its high insulation strength and flame retardant properties help ensure the safety and reliability of power distribution systems.
Communication equipment:
In the manufacture of communication equipment, GPO-3 boards are often used as components such as insulation gaskets, fixers and connectors. Its stable electrical performance and environmental resistance help ensure the reliability and stability of communication equipment.
In addition, it can also be used to manufacture transformers, capacitors and other electrical equipment insulation parts.

GPO-3 board Production process

Raw material preparation: Cut the alkali-free glass fiber felt board to the required size and shape, and prepare unsaturated polyester resin paste and additives.
Impregnation and laying-up: The cut glass fiber felt board is impregnated in an unsaturated polyester resin paste to ensure that the resin evenly penetrates into the felt board. Then the impregnated felt plate is stacked according to the predetermined number and direction to form the prototype of the plate.
Hot press forming: Put the laminated sheet into the hot press mold and apply the appropriate pressure and temperature for hot press forming. During hot pressing, the resin solidifies and binds tightly to the glass fibers to form a hard sheet.
Cooling and curing: After hot pressing, the board is removed from the mold and cooled. During the cooling process, the board is further solidified, ensuring stable performance.
Post-treatment: The necessary post-treatment of the plate, such as trimming the edge, removing burrs, etc., to meet the specific needs of customers.

GPO-3 board Authenticity discrimination

The true GPO-3 board has the following characteristics:
1. Through the United States Safety Laboratory certification (UL certification), there is an independent UL identification document number.
2. The density is between 1.81 and 1.83 (without fillers), which determines the reliable stability of the board.
3. When it burns, it will not produce smoke and toxic gases and will not burn stratified.
