PU, it can be said that recently the news is constantly, from the efficient performance in the external wall insulation is widely mentioned, to the 2013K exhibition will appear unique PU violin products, to the new BMW Iseta 250 is used as a booth to show PU seats and paint materials, PU development is visible to all.
In fact, PU has a very important application field, that is the pneumatic industry, PU pipe is the first choice of pneumatic pressure hose.
The reason for this is that PU pipe has a high transparency. If it is used as a pneumatic power pipe, the flow state of the corresponding medium in its internal is clearly visible. It is made of high resilience polyurethane raw material, so that the pneumatic tube has a smaller bending radius, more convenient installation, constant working pressure state use, longer life.
Because of its resistance to yellowing up to level 3, it is more difficult to turn yellow. The color is standard and bright, and will not fade for a long time. Moreover, the on-line pipe diameter control system can control the pipe diameter tolerance within ±0.12mm, greatly improving the grasp accuracy.
PU pipe has strong performance in elasticity, elongation, strength, and good damping performance, smooth inner wall, small liquid resistance, less hydraulic loss. At the same time, the resistance is good, non-toxic tasteless. Impact resistance, fatigue resistance, safety and reliability.
Compared with rubber materials, PU pipe can be said to be the best advantage.
PU pipe appearance is beautiful, hose bending radius is small, impact resistance, fatigue resistance, light and flexible, its weight is 30 to 70 percent of the rubber hose; Moreover, the oil resistance is good, 15-20 times of the oil resistance of natural rubber; And, wear resistance is good, is natural rubber wear resistance 30-50 times; Moreover, the aging resistance is good, 5 times of the aging resistance of natural rubber; In addition, the tensile strength of natural rubber is 3 times.
