PU plastic-reinforced pipes have the following characteristics: 1. **Good wear resistance**: Made of polyurethane material, both the surface and the interior possess wear resistance. Its wear resistance is 2-3 times higher than that of most rubber materials and 3-4 times higher than that of soft PVC. It can effectively resist the wear caused by various chemical substances and mechanical stresses, which can extend its service life. 2. **Wide temperature resistance range**: It can withstand temperatures ranging from approximately -30°C to 90°C, and can withstand a high temperature of about 120°C in the short term. It can maintain good elasticity and physical properties in extremely cold or hot environments, and will not become brittle or soft due to temperature changes. 3. **Corrosion resistance**: It can resist the corrosion of various chemical substances, including acids, alkalis, oils, and solvents, etc., and has good chemical stability. 4. **High pressure resistance**: With a unique structural design, such as the built-in high-strength plastic reinforcement, it has good pressure resistance performance and can withstand relatively high pressure. When bearing high-pressure fluids or materials, it can maintain its shape unchanged, ensuring a stable and smooth conveying process. 5. **Good flexibility**: It is lightweight, soft, and has good elasticity, with a small bending radius. It can be bent arbitrarily, and can easily achieve large-scale bending and twisting. After returning to its original shape, there will be no creases or damage, which is convenient for installation and use in complex environments. 6. **Anti-static property**: Some PU plastic-reinforced pipes have good anti-static performance. The pipe wall is equipped with copper wires, etc., to eliminate static electricity, which can prevent the accumulation and discharge of static electricity, and is suitable for suction places with static electricity. 7. **Environmental protection and hygiene**: It is non-toxic and odorless, contains no plasticizers, conforms to the concept of environmental protection, and is recyclable. When used for food suction and transportation, it will not contaminate the conveyed medium. 8. **Appearance characteristics**: Generally, it has a spiral structure made of transparent polyurethane material. The pipe wall is transparent, allowing the state of the internal fluid to be clearly seen, which is convenient for monitoring and control. The inner surface is completely smooth, and the outer surface has a spiral pattern, which is not only beneficial for enhancing the mechanical properties but also can play an anti-slip role. 9. **Good mechanical properties**: Reinforced with shock-resistant rigid spiral plastic reinforcement, it has ultra-high strength and an extremely long service life, strong axial compression strength, can withstand negative pressure, and can maintain its original shape in a vacuum state without gas and liquid leakage. It also has good resistance to ultraviolet rays and ozone, and strong anti-aging ability.
