Polyurethane Papermaking Roller - Coating Roller

Polyurethane Coating Roll - The聚氨酯造纸辊-涂布辊is a critical component in papermaking machinery for the coating process, consisting of a metal core coated with polyurethane elastomer. Its characteristics include:

       1. High Material Performance: Surface hardness up to Shore D75, with high elasticity (rebound rate ≥95%) and wear resistance (5-10 times that of rubber), suitable for high-speed, high-pressure conditions.

       2、Uniform Coating Ability: The rubber surface is fine and smooth, resistant to solvents (such as fountain solution, UV ink), ensuring even adhesion of paint or adhesive to the paper surface.

       3. Strong environmental resistance: Withstanding temperature ranges from -40℃ to 120℃ and acidic/alkaline environments, preventing roller swelling or deformation.

‌      4、Longevity Design: Composite bonding technology ensures adhesive strength ≥12MPa, combined with ultra-low Akron abrasion rate (≤0.05cm³/1.61km), offering a lifespan up to 2-3 times that of traditional rubber rollers. This roller is primarily used in paper sizing and soft calendering processes, enhancing the uniformity of the paper coating and the yield rate of finished products.
