Our Electronic Grade Fiberglass Cloth is made from high-purity electric grade fiberglass and woven using air-jet plain weaving machines, ensuring excellent uniformity and dimensional stability. Each fabric is treated with surface chemical treatment to enhance adhesion, insulation, and durability, making it ideal for high-performance electronics and insulation applications.
1.Wide Temperature Range
Electronic Grade Fiberglass Cloth can operate reliably in extreme temperatures from -70℃ to 550℃, making it suitable for high-temperature industrial, electronics, and insulation applications.
2.Aging & Environmental Resistance
Electronic Grade Fiberglass Cloth resists ozone, oxygen, sunlight, and long-term aging, ensuring durability and stable performance even in harsh environmental and outdoor conditions.
3.Excellent Electrical Properties
Electronic Grade Fiberglass Cloth offers high insulating performance, with a dielectric constant of 3–3.2 and breakdown voltage of 20–50 KV/mm, ideal for electrical and electronic applications.
4.Flexibility & Surface Friction
Electronic Grade Fiberglass Cloth provides good mechanical flexibility and high surface friction, allowing easy handling, precise lamination, and reliable adhesion in composite and insulation applications.
5.Chemical Resistance
Electronic Grade Fiberglass Cloth resists corrosion from most chemicals, ensuring long-term performance and stability in chemical environments, coatings, and industrial insulation systems.
FRP Products
Electronic Grade Fiberglass Cloth reinforces FRP laminates and structural components.
Copper Clad Laminates (CCL)
Used in PCB substrates, Electronic Grade Fiberglass Cloth ensures high insulation.
Aluminum Foil Laminates
