Fiberglass Board
Product Description Of Fiberglass Board
Product Introduction
Fiberglass board (also known as glass fiber board or FR-4 board) is a functional composite material made from glass fibers and high-temperature-resistant resins (e.g., epoxy resin). Free from harmful substances like asbestos, it meets modern industrial standards for environmental safety.
Material Composition and Physical Properties
Reinforced by glass fibers and bonded through high-temperature and high-pressure processes, the fiberglass board boasts a dense, uniform structure. It exhibits exceptional mechanical strength, high compressive resistance, and dimensional stability, maintaining performance even in extreme temperatures (-30°C to +150°C) or humid environments. Its dielectric properties are equally outstanding, with surface and volume resistance meeting industrial insulation standards, making it ideal for high-precision electrical applications.
Production Process and Technical Features
Through processes like resin impregnation, extrusion, and oven curing, the fibers and resin integrate to form a lightweight yet robust board. With a low thermal conductivity (0.03–0.05 W/m·K), it provides superior thermal insulation, while its noise reduction capability increases with thickness and density. The smooth surface allows direct precision machining (e.g., drilling, cutting) without secondary processing.
Specifications and Classification
Standard thickness ranges from 2 mm to 12 mm, with widths up to 3,658 mm and lengths extending to 12 meters, catering to diverse customization needs. Variants include standard, flame-retardant (FR-4), and ultra-thin types, suitable for electronics, construction, transportation, and more.
