Polyurethane Roller Coverings
Hot-cast polyurethane elastomers engineered for roller surfaces subject to extreme mechanical abrasion, dynamic loads, and high surface speeds.
MATERIAL SELECTION CRITERIA
What to Verify Before Selection
Different PU chemistry systems (NDI, MDI, TDI with polyester or polyether polyols) exhibit vastly different resistance to water hydrolysis, hot liquids, and cyclic heating. Durometer and color alone do not define performance.
MATERIAL SELECTION CRITERIA
Material Specification Checklist
- Process fluid/medium, concentration, and chemical Safety Data Sheet (SDS).
- Continuous operating temperature, thermal peaks, and cooling system.
- Linear nip load, rotational speed, and operating duty cycle.
- Wash solvents, cleaning agents, and documentation requirements (e.g. /).
MATERIAL SELECTION CRITERIA
From Raw Material to Finished Roller
Covering performance is evaluated in conjunction with core geometry, substrate bonding, and precision ground finish. Final parameters and manufacturing feasibility are agreed upon for your specific application.
