FR-4 (electronic cloth dipped in epoxy phenolic resin)
FR-4 by special electronic cloth dipped in epoxy phenolic resin material, such as by high temperature high pressure hot pressing a plate laminated products. With high mechanical properties and dielectric performance, good insulation and heat resistance and resistance to wet sex, and have good mechanical processing. Heat resistant level F grade.
Application: used for motor, electrical equipment for insulation structure parts, also widely used in PCB test; And can be in damp environment conditions and transformer oil in use.
High and low voltage transformer accessories, aviation electronic electrical insulation parts, water conservancy and hydropower in insulation parts, switch, frequency converter in insulation parts in insulation parts and furnace in insulation parts, semiconductor insulation parts, electrified railways, ship building insulation parts in insulation parts, nuclear power in insulation parts, bus duct insulation partitions washers.
