What is Polyurethane Roller

Polyurethane rollers are cylindrical rollers covered by a layer of elastomer material called polyurethane. Depending on the application, the inner roller core is prone to scratches, dents, corrosion, and other types of damage. The layer of polyurethane has intrinistic properties the inner roller core, such as abrasion resistance and impact strength. Polyurethane rollers are used in many manufacturing processes for performing operations such as:

Printing

Material Conveying

Squeezing

Pressing

Laminating

Feeding

Spreading

Coating

Grains Milling

Polyurethane is the most extensively used elastomer material for rollers. It is possible to make a variety of blends from different types and proportions of its compounding ingredients. Through blending, varying mechanical properties are obtained to suit a particular use. The most desirable properties of polyurethane are its toughness, high impingement resistance, shock absorption, and fatigue resistance.

Formulations of polyurethane can produce rollers that are hard and firm or soft and pliable. Polyurethane rollers are processed in hard to soft durometers depending on the requirements of an application. Polyurethane's durability and shock resistance make it one of the most popular types of roller compositions. In addition, polyurethane is an elastomer that can be thermoformed into any possible or conceivable shape.
