PU tube is short of Polyurethane Tubing. PU tube is the preferred pneumatic air pressure tube in pneumatic industry.
According to the materials, PU tubes can be divided into polyester PU tube, polyether PU tube; according to using requirements and appellation, they can be divided into PU air hose, PU tube clip increased yarn, PU industrial hose, PU wire extension tube, PU spiral, PU telescopic tube, PU spring tube, PU yarn folder, PU Braided Tube, PU textured tube, PU single tube, PU pipe.
PU tubes can also be divided into hard tube, hose and transparent tube. The main feature of PU tubes is excellent soft properties, to get minimum bend radius; PU tubes can be quite suitable for small space; PU tubes have good toughness, good low temperature performance, good bending resistance performance, flexibility, and transparent; can be used as air-conditioning low temperature refrigerant tube, air hydraulic pipe, fluid pipe, and spring water-resistant tubes.
The PU tube is mainly processed by the polyurethane elastomeric, and is made by extrusion, injection molding and other processes for production. Production process is various with the raw materials, products, equipment.
