The properties of Richeng's new PU pipe are as follows:

○The transparent tube has high transparency, and the state of medium flow is clearly visible.
○Made of high resilience polyurethane raw materials; making the pneumatic tube have a smaller bending radius and easier to install.
○The yellowing resistance reaches above level 3, and it is not easy to turn yellow.
○The color tube adopts imported weather-resistant toner, and the manufactured color tube has a standard color, bright, and will not fade for a long time.
○Using online pipe diameter control system, the tolerance of pipe diameter is controlled within △±0.12mm.
○Made of 100% high-physical plastic polyurethane elastomer, used under constant working pressure, longer life.
○Passed SGS certification and ROHS certification.

PU, it can be said that the news is constant recently, from the high-efficiency performance in external wall insulation being widely mentioned, to the 2013K exhibition there will be unique PU violin products, and then the new BMW Icerta 250 is used as a booth to display PU seats. And coating materials, the development of PU is obvious to all.
In fact, PU has a very important application field, that is, the pneumatic industry. PU pipe is the first choice for pneumatic pressure hose.
The reason for this is that the PU tube has high transparency. If it is used as a pneumatic power tube, the state of the corresponding medium flowing inside it is clearly visible. It is made of high resilience polyurethane raw materials, which makes the pneumatic tube have a smaller bending radius, more convenient installation, constant working pressure, and longer life.
Because the yellowing resistance reaches above level 3, it is more difficult to turn yellow, the color is standard, bright, and it will not fade for a long time. Moreover, the online pipe diameter control system can control the tolerance of the pipe diameter within ±0.12mm, which greatly improves the accuracy of grasping.
PU pipe has strong performance in terms of elasticity, elongation and strength, and has good damping performance, smooth inner wall, low liquid resistance and low hydraulic loss. At the same time, it has good resistance, non-toxic and tasteless. Impact resistant, fatigue resistant, safe and reliable. Compared with rubber materials, PU pipes can be said to have full advantages.
The PU tube has a beautiful appearance, a small bending radius, impact resistance, fatigue resistance, lightness and flexibility, and its weight is 30 to 70% of that of a rubber hose; and it has good oil resistance, which is 15- that of natural rubber. 20 times; and, good abrasion resistance, 30-50 times the abrasion resistance of natural rubber; and good aging resistance, 5 times the aging resistance of natural rubber; in addition, the tear resistance is 3 times that of natural rubber Times.
Not only the PU pipe has excellent performance and outstanding quality, from automobile manufacturing to civil engineering, from transportation to electromechanical mining machinery, especially when we buy leather bags and belts, we often hear the name of PU. It is used in shoes, synthetic leather , Aviation, medical and many other fields also occupy important positions.
