Electrical equipment generates a lot of heat during operation. If the insulation material cannot withstand high temperature, it is easy to cause the insulation performance to deteriorate or even fail, causing safety accidents such as short circuit or fire. FR5 epoxy sheet has excellent heat resistance and can maintain stable physical and chemical properties in high temperature environment. Its glass transition temperature is high and can be used for a long time at 155℃ or even higher without obvious softening, deformation or performance degradation.
For example, in high-temperature working scenarios such as industrial heating equipment and power transformers, FR5 epoxy sheet as an insulating component can effectively ensure the stable operation of equipment under high temperature conditions. Compared with ordinary insulation materials, FR5 epoxy sheet can still maintain excellent insulation resistance and dielectric strength in high temperature environment, avoiding performance degradation caused by temperature increase, thereby improving the safety and reliability of equipment.
Electrical equipment may be affected by various external forces such as vibration, impact, and stretching during operation. If the mechanical strength of the insulating material is insufficient, it is easy to break or damage, resulting in insulation failure. FR5 epoxy sheet has extremely high mechanical strength, including tensile strength, bending strength, and impact strength, and can withstand large external forces without being easily damaged.
In equipment such as motors and electrical switches, FR5 epoxy sheet is often used as an insulating support structure, which can effectively resist the vibration and impact force during the operation of the equipment and ensure the integrity and insulation performance of the structure. In addition, its excellent mechanical properties make it easy to process into insulating parts of various shapes and sizes to meet the installation requirements of different electrical equipment.
The core function of electrical insulation materials is to isolate current and prevent leakage and short circuit. FR5 epoxy sheet has extremely high insulation resistance and dielectric strength, which can effectively prevent current leakage and breakdown. Its dielectric constant is stable, the dielectric loss is low, and it can still maintain good insulation performance under the action of the electric field.
In high-frequency circuits and precision electronic equipment, FR5 epoxy sheet as an insulating substrate can ensure the stability and safety of signal transmission. Its low dielectric loss characteristics help reduce signal attenuation and interference and improve circuit performance. At the same time, its excellent insulation performance can effectively prevent electric shock accidents and ensure the safety of operators.
Electrical equipment may operate in harsh environments such as humidity and corrosive gases. If the insulating material is not resistant to chemical corrosion, it is easy to be damaged and affect the insulation performance. FR5 epoxy sheet has extremely strong chemical corrosion resistance and can resist corrosion from a variety of chemical substances such as acids, alkalis, and salts.
In harsh environments such as chemical and marine, FR5 epoxy sheet as an insulating material can effectively prevent chemical corrosion and extend the service life of equipment. For example, in electrical equipment in coastal lighthouses or chemical plants, it can withstand the long-term test of humid air, salt spray and corrosive gases, maintain stable insulation performance, and ensure the normal operation of equipment.
FR5 epoxy sheet shows extremely high stability in long-term use, has excellent flame retardancy and high electrical strength, and is suitable for demanding electrical systems. Its stable electrical performance and durability ensure the long-term reliable operation of equipment, reduce maintenance costs and failure rates.
In fields with high reliability requirements such as aerospace and rail transportation, FR5 epoxy sheet is widely used, and its long-term stability provides a solid guarantee for the safe operation of key equipment.
