Epoxy resin fiberglass board production process

Epoxy resin fiberglass board

Fiberglass board alias:
Fiberglass board, also known as glass fiber insulation board, glass fiber board (FR-4), glass fiber composite board, etc., is made of glass fiber material and high heat resistance composite material, and does not contain harmful asbestos components. It has high mechanical and dielectric properties, good heat resistance and moisture resistance, and good processability. Used in plastic molds, injection molds, machinery manufacturing, molding machines, drilling machines, injection molding machines, motors, PCBs, ICT fixtures, countertop polishing pads.

Injection molding usually requires:
High temperature materials and low temperature molds. Insulation methods must be used in the same machine. Keeping the injection mold at a low temperature does not make the temperature of the injection molding machine too high. This requirement can be met by installing an insulating insulation panel between the injection molding and the injection molding machine. Shorten production cycle, increase productivity, reduce energy consumption, improve finished product quality, continuous production process ensures product quality is stable, prevents machine overheating, no electrical failure, no leakage of hydraulic system.

Plywood with a glass rod dimension adhered to the surface of the fiberglass board is manufactured under high temperature and high pressure, and its outer surface has high quality moisture resistance. This type of board is suitable for use in the manufacture of containers. Available in sizes up to 3,658 mm, the board can be any size up to 12 meters. The glass fiber content is 25-40% by weight. The standard colors are gray and sub-white. The board can be cleaned with steam.

Epoxy fiberglass board features
Main technical features and applications of white FR4 light board: stable electrical insulation performance, good flatness, smooth surface, no pits, thickness tolerance exceeding standard, suitable for high performance electronic insulation requirements, such as FPC reinforcing board, tin furnace High temperature resistant board, carbon film, precision star wheel, PCB test stand, electrical (electrical) equipment insulation partition, insulation pad, transformer insulation, motor insulation, deflection coil terminal board, electronic switch insulation board, etc.

Glass fiber board production process
Among the epoxy fiberglass boards, FR-4 glass fiberboard has always maintained its absolute superiority and dominant position, occupying most of the middle and high-end market. The main reason is that FR-4 integrates various industrial properties. And it has high flame retardancy and is therefore favored by the market.
