Polyurethane is an amazingly durable and abrasion resistant material.
Because of this feature, urethane blower hose can be very lightweight and flexible and yet stand up to abrasion that would wear out comparable PVC or polyethylene hoses almost immediately.
Urethane Blower hose is great for insulation blowing, lawn cleaning, leaf collection and abrasive material chutes.
Polyurethane also remains flexible at very low temperatures.
