What is Polyurethane? Industrial Applications & Advantages
1. Polyurethane Material Structure & Core Properties
Polyurethane (PU) is a high-performance elastomeric polymer formed by the chemical reaction of isocyanate and polyol components. Combining the flexibility of rubber with the durability of plastics, this material plays an indispensable role in heavy industry and manufacturing.
2. Rubber vs. Polyurethane: Why Polyurethane?
Traditional rubber components lose their form or tear over time under friction and heavy loads. Polyurethane delivers the following technical advantages:
- Superior Abrasion Resistance: 5 to 8 times longer service life than standard rubber.
- High Load-Bearing Capacity: No permanent deformation under compression and impact.
- Oil & Chemical Resistance: High resistance to mineral oils, greases, and industrial solvents.
3. Industrial Applications
