Standard and custom-made technical textile structures ensure your duct product fully performs at expected rating strengths under specific underground conditions.
PVC extrusion coated fabric for mine & tunnel ventilation duct is kind of odorless and in-noxious light composite being made of high strength & low shrinkage Polyester mesh. It is hard to be pulled apart and torn off. Though modified characters of PVC, our fabrics has advantages of light weight, environmental protection, anti-aging, heatproof, cold-resistant, puncture-resistance, anti-flaming, anti-static electricity to make the ventilation ducting more than 2 times life time than the other materials. It is widely used for ventilation duct of mining, tunnel and underground projects etc.
Except these standard fabric types, we can also accept customization according to customer requirements. In addition, we also have partner factories that can provide customized PVC laminated fabrics to fully cover your needs for ventilation ducts in different market.
