Glass fiber board alias: glass fiber insulation board, glass fiber board (FR-4), glass fiber composite board, composed of glass fiber material and high heat resistance composite material, without asbestos harmful to the human body. It has high mechanical properties 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, PCB.ICT fixtures, and table polishing pads. Injection mold molding usually requires: high temperature material and low temperature mold. The heat insulation method must be adopted under the same machine condition. Keep the injection mold at a low temperature while not making the injection molding machine temperature too high. 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, and improve the quality of finished products. The continuous production process ensures stable product quality, prevents overheating of the machine, no electrical failure, and no oil leakage in the hydraulic system.
Main technical features and application of white FR4 light board: stable electrical insulation performance, good flatness, smooth surface, no pits, and thickness tolerance exceeding the standard. It is suitable for products with high-performance electronic insulation requirements, such as FPC reinforcement boards, through tin furnaces High temperature resistant plates, carbon diaphragms, precision cruisers, PCB test frames, electrical (electrical) equipment insulation partitions, insulation backing plates, transformer insulation parts, motor insulation parts, deflection coil terminal boards, electronic switch insulation boards, etc.
is also the so-called fiberglass board, which is generally used for soft-packing the base layer, and then covered with fabric, leather, etc., to make beautiful wall and ceiling decorations. The application is very wide. It has the characteristics of sound absorption, sound insulation, heat insulation, environmental protection, and flame retardant.
