Polyurethane hoses (also called PU hoses, PUR hoses, TPU hoes) are particularly abrasion-resistant and at the same time very flexible, light, durable and with long service life. They represent the best mechanical and physical properties of both PVC and rubber hoses. Compared to conventional PVC hoses, they are characterized by increased abrasion resistance and better temperature resistance. Polyurethane hoses have a good resistance to chemicals and weathering such as UV rays and ozone, while discolouration (the so-called yellowing) does not affect in any way their mechanical properties.
Another essential advantage of polyurethane hoses is that they do not harden over time as they do not require plasticisers to maintain flexibility, unlike PVC hoses that require adding of flexibility enhancer (such as plasticisers).
