Essential Properties and Advantages in Dynamic Applications
Polyurethane stands out for being highly resilient and extremely resistant to wear.
| Featured Property | Technical Detail and Field Benefit |
| Wide Range of Hardness | Hardness can be precisely adjusted for the application, offering everything from superior damping (low Shore A) to high load capacity and stiffness (high Shore D). |
| Superior Abrasion Resistance | Considered the industry standard against sliding and frictional wear, outperforming rubber and many plastics. It ensures maximum service life with constant contact. |
| High Load Capacity | Supports very high dynamic and static loads, ideal for components under pressure, such as wheels and rollers, minimizing permanent set (deformation after load relief). |
| Chemical Resistance to Oils | Excellent resistance to oils, greases, and solvents, making it ideal for components operating inside machinery and gearboxes. |
| Elasticity and Resilience | It has a high springback and shock absorption capacity, acting as an efficient vibration and noise absorber. |
Typical High Performance Applications
The versatility of PU allows it to be used in parts that require the best combination of strength and flexibility:
- Movement: High speed or load wheels, rollers and coatings.
- Sealing and Damping: Gaskets, scrapers, sealing rings and industrial dampers.
- Protection: Internal lining of ducts and buckets to protect against wear and impact from abrasive materials.
Fex Advantage: Choose PU to solve complex wear problems where rubber is too soft and hard plastic is too brittle.
