Few materials handle the underground environment as well as urethane. Between the grit, the moisture, the constant vibration and the sudden impacts, components made from the wrong material fail early and often. Urethane is built for exactly these conditions.

The properties that matter

Urethane sits in a useful middle ground — tough enough to take a hit, elastic enough to spring back, and far more abrasion-resistant than most rigid plastics or metals in sliding-wear applications.

• Abrasion resistance: it wears slowly against grit and slurry that would chew through alternatives
• Impact absorption: it deflects and rebounds rather than cracking under a knock
• Tear and load strength: it holds up under repeated mechanical stress
• Chemical and moisture tolerance: it stays stable in wet, contaminated conditions

We tune the formulation to the job. A guard that lives to take impact is built differently from a wear liner or a bush, and getting that hardness and resilience balance right is where in-house manufacturing pays off.

The practical upshot is longer service life and fewer change-outs — which means less downtime and lower cost per operating hour.
