First, the weight is light, the thickness of the TPU lining is generally 0.3mm, 2/3 thinner than the rubber lining, and the density of the TPU itself is lower than that of the rubber, so the total weight of each water belt can be reduced by 1/3, greatly reducing the load strength;

Second, high pressure resistance, although the rubber water belt is treated by secondary vulcanization, it can not completely eliminate the small leakage point, the bursting pressure is 3.9Mpa, and the TPU water belt bursting pressure is 5.72Mpa;

Third, good weather resistance, continuous use in the 80 ° C to 90 ° C high temperature environment, not embrittled at low temperatures. In addition, it has good wear resistance and oil resistance, and has low affinity with non-mineral oils, and is hardly eroded in fuel oil. Therefore, in Japan, Europe and the United States and other developed countries have long been the mainstream fire hose, and even used by the public as a common water pipe for planting flowers and plants.

TPU hose struction

Inner layer: Thermoplastic polyurethane (TPU)
Reinforcement: Woven Polyester jacket
