PU coated fiberglass fabric is a high-performance composite material manufactured by laminating polyurethane resin onto a woven fiberglass substrate.

• Remains pliable and resistant to cracking even at low temperatures
• Offers superior resistance to abrasion, oil, and chemical corrosion
• Features strong UV resistance and waterproofing for long-term outdoor use

• Used for welding curtains, machine covers, and partition screens
• Ideal for flexible HVAC ducting and ventilation systems
• Widely applied in inflatable structures, storage tents, and truck covers

Frequently Asked Questions

• Q1: Is PU coated fiberglass fabric waterproof?
  A: Yes, it is 100% waterproof. The polyurethane coating creates a seamless barrier that prevents water penetration while maintaining high tensile strength.
• Q2: How does PU compare to PVC coated fiberglass?
  A: PU coated fabric remains more flexible in low temperatures (down to -30°C) compared to PVC, and it is generally more environmentally friendly as it does not contain phthalates or heavy metal stabilizers.
• Q3: Can this material be welded or sewn?
  A: Yes. PU coated fiberglass fabric supports high-frequency welding, hot air welding, and sewing for custom fabrication into bellows, curtains, or ducting components.
