Where Can Find Customized Insulating Material Epoxy Resin?

Advantages of Epoxy Resins for Power Applications

Excellent insulating performance

Power-grade epoxy resins have exceptional dielectric strength, volume resistivity, and arc resistance, providing reliable insulation protection for power equipment. Their insulation performance is particularly outstanding under harsh electromagnetic environments with high voltages and high frequencies.

Excellent mechanical strength

By adding various inorganic and organic fillers, the mechanical strength of power epoxy resins, such as compressive strength, tensile strength, and impact strength, can be significantly improved. This enables them to withstand the various mechanical stresses generated during the operation of power equipment.

Excellent thermal aging resistance

Power epoxy resins have good thermal stability and high-temperature resistance, allowing them to operate at relatively high temperatures for an extended period without thermal aging and performance degradation. This is crucial for the reliable operation of power equipment.

Low coefficient of thermal expansion

Power epoxy resins' low coefficient of thermal expansion can effectively reduce the thermal stress caused by temperature changes, reducing the risk of cracking in insulating components.

Excellent electromagnetic shielding performance

Power epoxy resins can effectively absorb and block electromagnetic radiation, improving the electromagnetic compatibility of power equipment.

Good moldability and processability

Power epoxy resins can be processed using casting, injection molding, vacuum impregnation, and other techniques to manufacture complex insulating components.

We would be very pleased to provide detailed information and suggestions regarding customizing epoxy resin as an insulating material.

As an excellent insulating material, customized epoxy resin has a wide range of applications in the electrical and electronic industries, mainly used for manufacturing insulating parts such as motor windings, transformers, power modules, and circuit boards. Here are some key considerations and design points:

Dielectric performance: The dielectric strength, dielectric loss, and other parameters of the epoxy resin need to meet the specific requirements of the insulation application. The dielectric performance can be optimized by adjusting the resin formulation and curing process.

High-temperature resistance: Insulating materials need to operate stably at relatively high temperatures for an extended period, so the thermal stability and thermal aging resistance of the epoxy resin are very important. High-temperature-resistant epoxy monomers and curing agents can be selected.

Mechanical strength: Insulating parts are subjected to certain mechanical stresses during use, so the epoxy resin needs to have sufficient compressive, tensile, and impact strength. Various inorganic or organic fillers can be added for reinforcement.

Insulation resistance and surface resistance: Ensure that excellent insulation performance can be maintained even in humid environments, to prevent current leakage and electrical failures.

Molding process: Consider the fluidity and curing speed of the epoxy resin, and select appropriate casting, injection molding, or vacuum impregnation processes.

Environmental friendliness: Use non-toxic and harmless raw materials to reduce environmental impact.
