Product Description
Product Description
FR4 Sheet is a composite material laminated by epoxy resin and glass fiber cloth. It is widely used in electronics, electrical, communications and other fields due to its excellent electrical properties, mechanical strength and heat resistance. The "FR" in FR4 stands for "Flame Retardant", indicating that it has good flame retardant properties.
Performance Characteristics
Electrical insulation: high insulation resistance, low dielectric constant, suitable for high-frequency circuits.
Mechanical strength: high bending strength and impact resistance.
Heat resistance: can remain stable at higher temperatures, usually 130°C to 140°C.
Flame retardancy: meets UL94 V-0 flame retardant standards and has good fire resistance.
Chemical resistance: good resistance to most chemicals.
Dimensional stability: can remain dimensional stable under changes in temperature and humidity.
Advantages
High performance: excellent electrical and mechanical properties, suitable for demanding applications.
Flame retardancy: meets strict flame retardant standards and is highly safe.
Versatility: suitable for a variety of electronic and electrical applications.
Processability: easy to cut, drill and surface treat.
