Halogen free FR4 Fiberglass Sheet is made of electronic-grade glass fiber impregnated with halogen-free epoxy resin by hot pressing. The color is yellow. It is mainly used for insulating structural components in electrical and motor equipment. Because it does not contain halogen (including fluorine, chlorine, bromine, iodine, and arsenic), it will not produce toxic gases when burned, which meets the requirements of green production.

Halogen-free FR-4 Advantages:

First, environmental protection. In recent years, environmental pollution has been serious, and haze climate has appeared in many areas. People pay more and more attention to environmental awareness. Halogen-free FR-4 epoxy sheet is non-toxic and environmentally friendly.

Second, high temperature resistance. Halogen-free FR-4 epoxy sheet has good heat resistance, up to 150 degrees.

Third, insulation. The breakdown voltage of  Halogen-free FR-4 epoxy sheet is as high as 40KV. Although my country’s electricity consumption is constantly increasing and the voltage is gradually increasing, there is still a gap to reach the breakdown voltage of  Halogen-free FR-4 sheet .

Fourth, water absorption. It can be well resistant to moisture and moisture, and has a long shelf life.

Halogen-free FR-4 Application:

This product is mainly used as structural parts for halogen-free motors and electrical equipment, including various switches, electrical appliances, FPC reinforcement plates, carbon film printed circuit boards, computer drilling pads, molds and melting equipment (PCB test flame); it is also suitable for humid environments and transformer oil.
