Polyurethane Rollers Vs Rubber Rollers

Polyurethane Rollers Vs Rubber Rollers

Differences

Abrasion resistance: When the application requires increased load capacity and high friction, polyurethane surpasses natural rubber by far.

Durometer: Polyurethane has a wider range (10 Shore “OO” to 70 Shore “D”) while rubber is limited to 30 Shore A to 90 Shore A.

Marring of products: Rubber leaves marks when it comes in contact with other surfaces. Polyurethane, on the other hand, is non-marking – whether it has pigment added to it or not.

Wet environments: If used in a wet environment, rubber can rot over time but polyurethane is durable even when submerged or exposed to wet environments for an extended period of time.

Chemical composition: Fillers can be added to the rubber is to change its properties, but when it comes to urethane, the formulations are almost unlimited. This means engineers have more options based on the properties their application requires.
