The main material is imported prepreg, the color is white, yellow, green, still has high mechanical strength at normal temperature 130 °C, good electrical performance in dry and wet state, flame retardant, used in electrical, electronic, etc. Industry Insulation Structure Parts Synthesis: Epoxy phenolphthalein resin is impregnated by an electrician-free alkali-free glass fiber cloth, which is baked and hot pressed. Performance: It has high mechanical and dielectric properties, good heat resistance and moisture resistance, and good machinability. The heat resistance grade is B grade. Uses: Suitable for PCB test tools, fixtures and motors, electrical appliances for insulation structural components, and can be used in humid environments and transformers. Fiberglass board nickname: glass fiber insulation board, glass fiber board (FR-4), glass fiber preparation board, made of glass fiber material and high heat resistance composite material, containing asbestos component harmful to human body. It has low mechanical and dielectric properties, good heat resistance and moisture resistance, and good processability. Used as plastic molds, injection molds, machinery manufacturing, molding machines, drilling machines, injection molding machines, motors, PCBs. ICT fixture, countertop polishing pad. Glass fiber board, also known as MDF, is a wood-based board made of wood fiber or other vegetable fiber, which produces urea-formaldehyde resin or other limited adhesive. Adhesives and/or additives can be produced during the production process. The fiberboard has the advantages of uniform material distribution, small staggered strength difference, easy cracking, and the like, and is widely used. It takes about 2.5 to 3 cubic meters of wood to produce 1 cubic meter of fiberboard, and can replace 3 cubic meters of sawn timber or 5 cubic meters of logs.
