Alias ​​of glass fiber board: glass fiber insulation board, glass fiber board (FR-4), glass fiber composite board, etc., which is composed of glass fiber material and high heat resistance composite material, without harmful asbestos ingredients. It has higher mechanical properties and dielectric properties, better heat resistance and moisture resistance, and has good workability. Used in plastic molds, injection molds, machinery manufacturing, molding machines, drilling machines, injection molding machines, motors, PCBs, ICT fixtures, tabletop grinding pads. Injection molds usually require high-temperature materials and low-temperature molds. The heat insulation method must be adopted under the same machine condition. Keep the injection molding temperature low while not overheating the injection molding machine. This requirement can be met by installing an insulation board between the injection mold and the injection machine. Shorten the production cycle, increase productivity, reduce energy consumption, improve the quality of finished products, continuous production process to ensure product quality is stable, prevent overheating of the machine, no electrical failures, no oil leakage in the hydraulic system.

Plywood with glass fiber adhered on the surface of the glass fiber board is manufactured under high temperature and high pressure, and its outer surface has high quality moisture resistance. This kind of board is suitable for manufacturing containers. The sizes supplied are: board width up to 3658 mm, board length 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 [1].
