Polyurethane Prepolymer for PU Rollers is specially formulated for the production of high-performance polyurethane rollers. Based on polyester polyols and TDI, this prepolymer offers excellent abrasion resistance, resilience, and load bearing capacity, making it ideal for a wide range of industrial applications.
Comparative Overview: Polyurethane Vs Rubber Rollers
|
Attribute |
Polyurethane Rollers |
Rubber Rollers |
|
Elasticity |
Superior in certain formulations, adaptable to varying hardness. |
Inherently elastic, suitable for many applications. |
|
Abrasion Resistance |
Highly resistant, especially under heavy loads and high friction. |
Less resistant compared to polyurethane. |
|
Wet Environment Suitability |
Resistant to degradation, even when submerged or exposed to moisture. |
Vulnerable to rotting or degrading in damp conditions. |
|
Chemical Composition |
Offers room for custom formulations, adapting to specific needs. |
Might be altered with specific fillers, but sensitive to certain chemicals. |
|
Propensity to Leave Marks |
Non-marking property ensures minimal product contamination. |
Has a propensity to leave marks, especially on delicate items. |
|
Manufacturing & Industrial Use |
Versatile and widely used in various manufacturing processes. |
Long-standing history in numerous industries. |
|
Environmental Impact |
Depending on the formulation, some types might be more eco-friendly. |
Generally, has a larger environmental footprint, especially if not recycled. |
|
Cost |
Often a higher initial investment than rubber. |
Typically less expensive initially but may incur costs in the long run due to durability issues. |
