When comparing service life between polyurethane and rubber screen panels, polyurethane generally lasts significantly longer in most mining and aggregate applications—typically 3–5× longer than rubber in abrasive conditions. Premium polyurethane panels deliver 6× longer wear life than rubber in high-abrasion iron ore applications. Rubber's advantage is impact absorption—it excels with very coarse feed (>100 mm) and high-drop-height applications. In most modern mineral processing operations, premium polyurethane panels deliver the best combination of impact resistance, abrasion resistance, and extended service life.
