5. FAQ
Q1. What are the characteristics of PU material?
A1. Polyurethane (PU) is a versatile polymer with a wide range of properties that make it suitable for various industrial and consumer applications. Below are its key characteristics:
(1). Mechanical Properties:
High Elasticity & Flexibility – PU can be formulated to be soft (like foam) or rigid (like plastic);
Excellent Abrasion Resistance – More durable than rubber in high-wear applications;
Good Tensile Strength – Resists tearing and deformation under stress;
Load-Bearing Capacity – Used in shock absorbers, wheels, and structural components.
(2) Chemical Resistance:
Resistant to Oils & Greases – Ideal for seals, gaskets, and hydraulic components;
Moderate Acid/Base Resistance – Handles weak acids/bases but degrades in strong chemicals;
Poor Solvent Resistance – Swells or dissolves in ketones, esters, and chlorinated solvents.
Q2. can you tell me the difference between dust seal PU materal and dust seal rubber material ?
A2. Here is a table to show you their differences of functional:
| Feature | PU Dust Seal | Rubber Dust Seal |
| Sealing Effectiveness | Better for dynamic, high-wear applications | Better for static/low-friction seals |
| Lifespan | Longer in abrasive environments | Shorter under heavy wear |
| Cost | Higher (due to performance benefits) | Lower (economical for general-purpose use) |
| Installation | May require precise fit (stiffer material) | Easier to install (more flexible) |
