Polyurethane-coated rings and spacers
The exceptional combination of high tensile strength and high elongation at break allows the coating to absorb the cyclical shocks of contact with the metal strip without fatigue. Low compression set ensures that the ring maintains its operating diameter even after thousands of hours of continuous operation, a critical aspect for maintaining cutting quality and slippage.
The polyurethane coating of rings and spacers provides machining service centers with a series of advantages that increase process quality and efficiency:
– Abrasion resistance: Thanks to its superior resistance to rubber in contact with cut edges, it drastically reduces replacement frequency.
– Quiet operation: The high internal damping factor of the PU reduces line noise and vibrations transmitted to the structure.
– Zero contamination: PU leaves no residue on the surface: essential for steels intended for painting or galvanizing.
– Chemical resistance: Compatible with rolling oils, cooling emulsions, and solvents commonly found in sheet metal processing lines.
The polyurethane coating of the rings and spacers is cast directly onto the metal core, using a specific primer to ensure superior adhesion. The finish can vary according to requirements, but performance is the strong point of this technical solution.
