Valley Roller's Premium Rock Series was developed specifically to meet the demands of paper industry rolls requiring 0-1 P&J hardness.
Based on innovative formulas, these roll coverings achieve more than just the required hardness. They provide superior performance in chemical resistance, hardness stability, hysteresis, heat stability, abrasion resistance, thermal expansion and friction requirements.
The stability of the Premium Rock Series roll coverings make them ideal for nip applications under a broad spectrum of operating conditions. Exposure to paper mill chemicals, nip loads and high speeds are no threat to the high-performance characteristics of these advanced, bone-hard coverings.
