What is the rated temperature of GPO-3?

What is GPO-3 board?

GPO-3 board, also known as GPO-3 laminate 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.

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.

What is the rated temperature of GPO-3?

The GPO-3 board provides excellent protection and spatial stability during heating and has UL (Underwriters Laboratories) temperature ratings in the following temperature ranges:

Electronic application: 120~210℃

Mechanical application: 130~210℃

Why do I need to know the rated temperature of GPO-3?

1. Ensure stable material properties

GPO-3 is a kind of hard plate insulating material made of alkali-free glass fiber felt plate immersed in unsaturated polyester resin paste and added with corresponding additives. It has excellent electrical and mechanical properties, but the stable play of these properties needs to be within a certain temperature range. Knowing the temperature rating of GPO-3 ensures that the material will not change in performance due to too high or too low temperature during use, thus maintaining its stable electrical and mechanical properties.

2. Avoid material damage

GPO-3 insulating material requires strict temperature control during use. If the temperature exceeds its rated range, it may lead to thermal deformation, thermal aging or even thermal decomposition of the material, thus damaging the material. Understanding the rated temperature of GPO-3 can help users to control the temperature reasonably during the use of the material to avoid damage due to high temperature.

3. Ensure the safe operation of equipment

GPO-3 insulating material is usually used in electrical and mechanical equipment as an insulating layer or structural support. If the material is damaged due to high temperature, it may lead to short circuit, leakage and other safety hazards in the equipment. Knowing the rated temperature of GPO-3 ensures the safe operation of the material in equipment and avoids equipment failures or safety accidents caused by material damage.

4. Guide material selection and application

Understanding the rated temperature of GPO-3 helps to choose the right model and specification according to the temperature requirements of specific application scenarios when selecting materials. At the same time, in the process of material application, it is also possible to formulate a reasonable use and maintenance program based on the rated temperature to ensure that the material can operate stably for a long time.

Characteristic of GPO-3 board

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.
