However, a new fire hose becomes more and more popular recent years. That is the PU lined fire hose.

Why the PU lined fire hose is popular?
Because it has great properties. First is the high strength. The tearing strength is 3 times of the natural rubber. Second is the abrasion resistance, which is 5 times of the natural rubber. Third is the oil resistance, that’s to say oil will never corrode the hose. Last is the temperature resistance. The great property of PU makes the hose can bear 90℃, while it can remain flexible even in -70℃.
Besides the great property of rubber, it resists high pressure, weather and torsion. What’s more, it’s 40% lighter than the rubber lined fire hose. Therefore, it can reduce the fire fighter’s heavy burden and make the fire fighting more easier.
