7628 Fiberglass Cloth is an electronic-grade E-glass woven fabric designed for high-performance laminate, electrical insulation, and composite reinforcement applications.
Manufactured with fine-denier continuous filament glass fibers and woven in a uniform plain weave pattern, this fabric offers excellent strength, dimensional stability, and superior dielectric performance.
With smooth surface quality, consistent thickness, and excellent resin wet-out, 7628 is widely used in PCB laminates (FR-4), composite panels, structural parts, and industrial insulation.
Excellent electric insulation
Fire-resistance
High temperature resistance
Weather resistance
Highstrength
High modulus.
