Plastex is Hamilton's phenolic wheel — a dense composite rated to 5,000 lb per wheel, engineered for the oil-exposure, low-rolling-resistance, high-cycle applications where polyurethane degrades and soft wheels wear out. It's a staple of Hamilton's heavy industrial caster platforms.
Plastex carries heavy load with low rolling resistance — meaning less push force per pound moved. It resists the oils and cutting fluids that break down polyurethane over time, which makes it a machine-shop and manufacturing-floor standard. And it's dimensionally stable: it won't cold-flow or flat-spot under sustained static load the way softer materials can.
Like all phenolic, Plastex is hard — it transmits floor shock to the load and runs noisier than polyurethane or rubber. It's brittle under sharp impact. Spec it where its strengths matter (oil exposure, low rolling resistance, high cycle count, heavy steady load) and choose a cushioned material where ride quality and impact tolerance matter more.
Plastex is Hamilton's branded phenolic composite — a dense, hard, oil-resistant wheel material rated to 5,000 lb per wheel.
Plastex resists oils and solvents and rolls with lower resistance under heavy load. Polyurethane protects the floor and rides quieter. Different jobs.
No — it's dimensionally stable under sustained static load, a key advantage over softer wheels.
Our US-based caster engineers will match the right build to your load, floor, and application.
