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.
Continuous filament fibers and balanced weave provide strong mechanical reinforcement.
Uniform yarn distribution ensures consistent thickness and high laminate flatness.
E-glass composition offers low dielectric constant, high breakdown voltage, and stable insulation performance.
Suitable for applications requiring thermal stability and low thermal expansion.
Performs reliably in harsh or corrosive industrial environments.
Plain weave structure ensures easy lay-up and efficient wet-out with various resin systems.
