Epoxy resin board/glass fiber board Composition: special electronic grade alkali-free glass fiber cloth impregnated with epoxy, epoxy resin by high-temperature hot-pressing and become the board laminated products Performance: insulation, heat insulation Heat resistance: 140 degrees Voltage resistance: 10KV Hardness: 118-120HR Electricity-induced rate: 4.4-4.6 Dimensions: 1020*1220mm, 1090*1245 Thickness: 0.1-80mm Colors: Yellow, aqua green, black Advantages: flat, uniform thickness tolerance, in line with ROSH, REACH, halogen-free requirements Usage: used in electric motors, electrical equipment for insulating structural components, and can be used in humid environmental conditions and transformer oil; PCB test racks, jigs and fixtures production, mold insulation boards, FPC reinforcing, tin furnace jigs and fixtures.
Black fiberglass board is made of fiberglass cloth impregnated with epoxy resin as adhesive, dried and hot-pressed into a board-shaped insulating material. It has high mechanical properties, water absorption, flame retardancy and heat resistance, and stable dielectric properties after immersion in water.
Suitable for high-performance electronic insulation requirements of products, such as FPC reinforcement board, PCB drilling pads, fiberglass meson, potentiometer carbon film printed fiberglass board, precision vernier gears (wafer milling), precision test panels, electrical (electrical) equipment, insulating spacers spacers, insulating pads, transformer insulating boards, motor insulation, grinding gears, electronic switches insulating boards, and so on.
Various colors: Compared with 3240 yellow, FR-4 has white, yellow, aqua green and black colors to choose from. And the surface is flat and smooth without bubbles, beautiful appearance.
Fire rating: UL94V0, a high level of fire protection. Unlike the general fireproof grade, UL94V0 has already achieved the effect of fireproof and flame retardant. It can self-extinguish in a short time after the material has gone through the burning state, which protects the safety of life and property.
Strong insulation: FR-4's natural insulation is extremely strong, in both dry and wet state, the electrical performance is still very good, is a good choice for electrical insulation parts.
High quality and practicality: FR-4 is still very adaptable when facing different environments. Whether it is -100℃ or 130℃, it can be applied.
Wide range of applications: Because of FR-4's high quality performance, coupled with strong plasticity, it is widely used in electrical and electronic insulating parts, as well as insulating panels for airplanes, moving vehicles, transformers, precision cruise wheels and so on.
