Brief Introduction of Polyurethane Layflat Hose
Features: Polyurethane (PU) has excellent comprehensive properties and many valuable properties from rubber to plastics. First, it has high strength, its tear strength is about 3 times of natural rubber; second, it has good wear resistance, about 3-5 times of natural rubber; third, it has good oil resistance, low affinity with non-mineral oil, and is hardly corroded in fuel oil; fourth, it has good weather resistance, and it can be used continuously in high-temperature environment from 80 to 90 degrees, and it does not embrittle at low temperature from - 50 to - 70 degrees.

The polyurethane fire-fighting water belt produced by imported equipment and imported raw materials not only has all the advantages of rubber water belt but also has excellent characteristics of high-pressure resistance, oil resistance, weather resistance, corrosion resistance and winding resistance. It is light in weight, flexible and convenient in use. The weight per unit length is lighter than rubber lining water belt by more than 40%. It is a new generation product to reduce the fire-fighting intensity and improve fire-fighting performance. Fire-fighting water belts are favoured by the vast number of users. Developed countries such as Japan, Europe and the United States have already become the mainstream fire water belts, and even been used as common water pipes for planting flowers, planting grass and flushing. In China, because of its high cost of raw materials and high hose pipe price, most of the equipment was imported, and it was not popularized until the late 1990s. At present, fire protection* mostly starts to equip with polyurethane fire water belts. Many industrial and mining enterprises, petrochemical oil depots, ship terminals and high-end buildings have begun to be used in large quantities.
