(1) Polyurethane rubber rollers have good chemical properties and are suitable for various types of inks and printing methods. It has special resistance to solvent components in various inks, fountain solutions and cleaning agents.

(2) The colloid used for polyurethane rubber rollers has sufficient surface viscosity to ensure that the rubber roller has good ink transfer and ink repellency during the printing process, and its good ink affinity can ensure high-quality printing.

(3) The appearance is bright in color, the colloid surface is fine and smooth, and the colloid material and the mandrel are firmly bonded. The size of the rubber roller is strictly controlled, and the size will not change greatly under different temperature and humidity conditions.
