The Characteristics of Polyurethane Roller

The Characteristics of Polyurethane Roller

Polyurethane roller are suitable for supporting rollers for new materials such as glazing, oiling, metallurgy, and iron printing of equipment, and have a wide range of applications.

     1. The hardness index is wide, which can meet the hardness requirements of different types of mechanical rubber rollers.

     2. The surface of the colloid is fine and smooth, the appearance is bright, 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 with temperature and humidity.

     3. Good performance, suitable for different types of inks and printing methods.

     4. The surface viscosity of the colloid used for polyurethane roller can make the rubber rollers have good ink transfer and ink holding performance in the printing process, and its good ink affinity can make printing.

     5. The physical properties of polyurethane roller, long-term use of rubber rollers will not age, and the tear resistance, resilience performance is good, and wear resistance is good, so the use time is long, easy to store, long-term storage does not affect the use; can withstand high Pressure, high speed, high temperature, high humidity production environment.

      6. Easy to clean, easy to switch between dark and light inks, and convenient for printing and color changing.

      7. Polyurethane roller have excellent hydrophilicity, so they can be used as rubber rollers in water and alcohol dampening systems.
