Product Overview
Fibre glass epoxy sheets are high-performance composite laminates manufactured using woven fiberglass fabric impregnated with epoxy resin under controlled heat and pressure. These sheets are engineered for applications where electrical insulation, mechanical strength, and dimensional stability are critical. Due to their excellent dielectric properties, fibre glass sheets are widely used in switchgear assemblies, transformer insulation systems, panel boards, and high-voltage components. The epoxy matrix provides superior bonding strength while the fiberglass reinforcement ensures rigidity and impact resistance. Compared to traditional insulation materials, fibre glass epoxy sheets offer significantly higher tensile strength, better resistance to moisture absorption, and improved thermal endurance. This makes them suitable for continuous industrial operation environments where reliability is non-negotiable.
