High Mechanical Strength
Woven from continuous E-glass filaments, 7628 cloth exhibits high tensile strength and resists tearing and puncture. This makes it an ideal reinforcement material, providing structural rigidity to laminates and composite parts.
Excellent Thermal Resistance
The fabric can withstand continuous operating temperatures up to 550°C (1022°F). This high-temperature tolerance is crucial for applications that undergo soldering processes or operate in hot environments, preventing degradation.
Superior Electrical Insulation
E-glass is a renowned electrical insulator. 7628 cloth has a high dielectric strength and low dielectric constant, making it the primary material for isolating conductive layers in PCBs and other electronic components to prevent short circuits.
Good Chemical Resistance
Fiberglass is resistant to most chemicals, oils, and solvents. This property ensures the material’s longevity and reliability when exposed to various chemicals during manufacturing or in its end-use environment.
