FR4 flame retardant board is a plate-shaped insulating material made of glass fiber cloth impregnated with epoxy resin as an adhesive, dried and hot-pressed. It has high mechanical properties, water absorption, flame retardancy and heat resistance, and the dielectric properties are stable after immersion in water.

The mechanical properties, dimensional stability, impact resistance and moisture resistance of FR4 flame retardant board are higher than those of paper board. It has excellent electrical performance, high operating temperature, and its performance is less affected by the environment. In terms of processing technology, it has great advantages over other resin glass fiber cloth substrates. This type of product is mainly used for double-sided PCB, and the amount is very large.

Product Description:

1. Various colors: Compared with 3240 yellow, FR-4 is available in white, yellow, aqua, and black. And the surface is smooth and smooth without bubbles, and the appearance is beautiful.

2. Fire rating: UL94V2, fire rating H. Different from the general fire rating, UL94V2 has achieved the effect of fire retardant. After the material passes through the burning state, it can self-extinguish in a short time, escorting the safety of life and property.

3.Strong insulation: The natural insulation performance of FR-4 is still very good in dry and wet states, and it is a good choice for electrical insulating parts.

4.High-quality and practical: FR-4 still has good adaptability in the face of different environments. Whether it is minus 100 ℃ or high temperature 130 ℃, it can be applied.

5. Wide range of applications: Because of the high-quality performance of FR-4, it is widely used in electrical and electronic insulation parts, as well as aircraft, motor vehicles, transformer insulation boards, precision cruisers, etc.
