Rubber roller coverings are evaluated for hardness, resilience, abrasion, surface finish, media contact and consistency. Both SBR and NBR can be relevant depending on what the roller touches and how it operates.
Map the operating conditions
Provide the roller function, contact material, speed, load, temperature and cleaning media. These details help separate general-purpose requirements from oil-resistant service.
Surface and Wear
Clarify abrasion, grip, release, marking and required surface finish.
Media and Temperature
Identify oils, solvents, water, cleaning agents and the continuous operating temperature.
Production Control
Share target hardness, dimensions, bonding method, current compound and acceptance tests.
Information to Provide
- Roller function, diameter and covering thickness
- Contact surface and cleaning method
- Target hardness and abrasion requirement
- Temperature, speed and load
- Current grade and trial quantity
Evaluation Note
A raw-polymer comparison cannot predict complete roller performance. Compound design, cure, bonding and finishing all affect the result and require buyer validation.
