Thanks to its excellent properties-such as high strength, high-temperature resistance, corrosion resistance, and superior electrical insulation-fiberglass cloth plays a pivotal role across various sectors, as detailed below:
Electronics and Electrical Sector
Insulation and Structural Support: Serving as a core substrate for copper-clad laminates and printed circuit boards (PCBs), it provides electrical insulation and mechanical support for circuits in devices such as smartphones, AI servers, and automotive electronics. It prevents chip failure caused by heat-induced warping and ensures stable high-speed signal transmission.
Electrical Insulation and Protection: Used in transformer coils, motor insulation layers, and cable wrapping to prevent electrical leakage and short circuits, thereby enhancing the operational safety of power equipment.
Construction and Engineering Sector
Structural Reinforcement and Crack Prevention: Applied to the surfaces of beams and columns in aging buildings to boost structural load-bearing capacity and seismic resistance; it can also be applied to wall surfaces or over exterior insulation layers to prevent wall cracking and the detachment of insulation materials.
Waterproofing, Anti-corrosion, and Moisture Protection: Acts as a reinforcement layer for roofing waterproofing membranes to enhance tensile strength; it is also used to wrap water supply, drainage, and underground piping to prevent moisture-induced rusting and corrosion, thereby extending the service life of the infrastructure.
