Advantages of Polyurethane Rollers

Advantages of Polyurethane Rollers

1. The appearance is bright in color, the surface of the colloid 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.

2. Polyurethane rubber rollers have a wide range of hardness indicators, from HSA15 to HSD80, which can meet the hardness requirements of different types of printing machines for rubber rollers.

3. The colloid for polyurethane rubber rollers has sufficient surface viscosity to ensure that the rubber rollers have good ink transfer and ink holding performance during the printing process, and its good ink affinity can ensure high-quality printing.

4. Polyurethane rubber rollers have good chemical properties, especially good solvent resistance to diesel, gasoline, lubricating oil, kerosene, alcohol and saline solution.

5. Polyurethane rubber rollers have excellent physical properties. Long-term use of rubber rollers will not harden or age, and they have good tear resistance, rebound performance, and excellent wear resistance, so they have a long service life and are easy to store. Affect the use effect; able to withstand the production environment of high pressure, high speed and high humidity.

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

7. Polyurethane rubber roller has high strength and high tear resistance, so it is resistant to shearing and wear.
