It boasts excellent tear resistance, outperforming ordinary rubber and plastic tubes in this regard, making it suitable for use in a wide range of challenging environments. The tube also exhibits excellent elasticity, ensuring a longer service life.

PU tubing, also known as TPU tubing, is a type of transparent pneumatic hose made by modifying a polyurethane-based formula and then extruding it at high temperatures, followed by vulcanization. Polyurethane is synthesized through the polymerization of organic diisocyanates or polyisocyanates with diols or polyols. Primarily used in automated pneumatic systems, this tubing efficiently transports compressed air to control cylinder movements, enabling the entire system to function smoothly. It stands out for its flexible tube structure and excellent oil resistance—particularly beneficial when used with air compressors, where oils may inadvertently enter the tubing or contaminate its surface. Testing has shown that PU tubing exhibits superior oil resistance compared to nitrile rubber hoses, making it an ideal choice for such applications.

The wear resistance coefficient reaches 0.2 g/dm², enabling the efficient conveyance of various granular materials such as plastic pellets, flour, and different types of dust. Additionally, the PU tubing exhibits excellent anti-adhesion properties, effectively preventing pipeline blockages and helping to reduce production costs. The smooth inner surface minimizes friction during gas and liquid flow, leading to significant energy savings.

It boasts excellent tear resistance, surpassing that of ordinary rubber and plastic tubes, making it suitable for use in a wide range of challenging environments. The tube also exhibits outstanding elasticity, ensuring a longer service life.
