\u003cstrong\u003ecaster wheel material\u003c\/strong\u003e depends on three factors: floor type, load weight, and operating environment. \u003cstrong\u003ePolyurethane\u003c\/strong\u003e handles 90% of indoor industrial applications (50-3,000 lb per caster) with quiet, floor-safe rolling. \u003cstrong\u003eMold-on rubber\u003c\/strong\u003e is the standard for shock absorption and floor protection on glossy concrete. \u003cstrong\u003ePhenolic\u003c\/strong\u003e takes heat up to 475°F and high static loads. \u003cstrong\u003eCast iron and forged steel\u003c\/strong\u003e handle the heaviest loads (up to 22,800 lb) on rough surfaces but mark soft floors. \u003cstrong\u003eThermoplastic rubber (TPR)\u003c\/strong\u003e is the quietest non-marking option under 300 lb. \u003cstrong\u003ePolyolefin\u003c\/strong\u003e is the cheapest food-grade, chemical-resistant choice.
