PU Lining is specially designed for fire fighting. However, it gradually serves in many other applications because it integrates many advantages. These include agriculture, forest, ship building, mine, and municipal industries.
It has excellent tear resistance, which is about 3 times that of natural rubber.
The high tensile polyester braid layer enables the hose to bear higher pressure, with a max working pressure of 2.5Mpa.
Excellent elasticity allows the fire hose to recover to its previous shape even after external crushing during usage.
Can work at 80℃ for a long time without property changes and remains flexible even at -40℃ without becoming brittle.
Strong aging resistance ensures a long service life, reducing change frequency and saving significant costs.
Resistant to acid, alkali, chemicals, and fuel oil. Wear resistance is 3-5 times higher than natural rubber.
Frequently Asked Questions
Q1: What are the main applications for PU lining hoses?
