ETERNATHANE® 

Durable Low Hardness Polyurethane Solutions for Mining Applications

Mining environments place extreme demands on materials. Constant exposure to abrasive media such as slurry, sand, and gravel accelerates wear, increases maintenance requirements, and leads to unplanned downtime. In these conditions, conventional materials often struggle to combine durability, flexibility, and long-term performance.

Low hardness polyurethane elastomers based on ETERNATHANE® polycarbonate-based urethane prepolymers have been developed to address these challenges. These advanced systems are designed specifically for demanding industrial applications where both abrasion resistance and dynamic performance are essential.

Unlike traditional polyether- or polyester-based polyurethanes, ETERNATHANE® polycarbonate-based solutions offer a unique balance of properties. Even at low hardness levels, they deliver high abrasion resistance and excellent rebound, enabling effective absorption of repeated impacts without compromising material integrity. This makes them particularly suitable for mining components exposed to continuous mechanical stress.

Another key advantage is their outstanding resistance to hydrolytic and thermal stress. Mining operations often involve moisture, elevated temperatures, and harsh operating conditions. ETERNATHANE® low hardness PU systems retain a high level of mechanical performance even after prolonged exposure to water and heat, ensuring reliable operation and extended service life.

These characteristics make ETERNATHANE®-based low hardness polyurethane elastomers ideal for applications such as mining screen panels, chute liners, and wear-resistant flexible pads. By reducing wear-related failures and maintenance frequency, they help improve operational efficiency and lower overall costs.
