Features of FR5 Epoxy Glass Fiber Laminates

Excellent Electrical Insulation Performance

FR5 epoxy glass fiber laminates have high insulation resistance and breakdown voltage, which can effectively isolate the risks of current leakage and breakdown, and build a reliable insulation protection for electronic devices. Its low dielectric constant and dielectric loss factor can reduce signal attenuation in high-frequency circuits and ensure the stable transmission of signals, making it an ideal choice for high-frequency electronic devices.

Good Mechanical Properties

This material has both high strength and high stiffness, and can withstand large external forces and pressures without being easily deformed. At the same time, it also has a certain degree of toughness and impact resistance. When encountering external impacts, it can protect the internal electronic components from damage and ensure the structural integrity of the equipment.

Outstanding Thermal Stability Performance

FR5 epoxy glass fiber laminates have a high thermal deformation temperature and can still maintain stable performance in a high-temperature environment. This characteristic enables it to be widely used in electronic devices with strict temperature requirements, meeting the usage needs under special working conditions.

Strong Chemical Corrosion Resistance

Whether facing acids, alkalis, or chemical substances such as salts, FR5 epoxy glass fiber laminates show extremely strong corrosion resistance. Even in a harsh chemical environment, it can maintain stable performance,which significantly extends the service life of the equipment.
