The greatest qualities of both rubber and plastic are combined in polyurethane, which is frequently referred to as PU, PUR, or TPU. It has high elongation values (stretchability) comparable to rubber and superior to PVC abrasion resistance. Due of its inherent flexibility, polyurethane does not require additives to maintain its flexural qualities.
Polyurethane stands out from other thermoplastics due to its exceptional weathering capabilities and good chemical resistance. Comparatively speaking, PVC or rubber are less resistant to pressure and vacuum applications than polyurethane.
There are some significant distinctions between the two primary urethane formulations, ester and ether. Urethane with an ester composition is attacked by water, which significantly reduces its physical qualities. Particularly in humid conditions, ether urethanes display significantly greater hydrolytic stability. Additionally, ether-based materials are more fungus-resistant than ester-based ones.
In general, PVC is stickier than polyurethane. It might stick to itself, which can lead to tangles, especially with tubing. To lessen tackiness, additives can be incorporated into the polyurethane resin during manufacturing. PVC by itself naturally has a slipperier surface than 100% polyurethane, while material combinations like PVC/polyurethane mixes can significantly alter the surface properties.
Pneumatic control systems, cable jacketing, air lines, powder and granular material transfer, fluid lines, sleeving, low pressure hydraulics, and robots are a few typical applications for polyurethane tubing.
