TDF manufactures coated fabrics such as clear and opaque PU (Polyurethane), TPU, or Thermo PU which contain the properties of being waterproof, lightweight, and tensile.
Waterproof characteristics are represented by water pressure resistance coefficient; PU coating fabrics used in tents commonly have a water pressure resistance coefficient of 600mmH2O – 3000mmH2O with 600mmH2O being suitable for regular rain and 3000mmH2O being suitable for downpours.
