The salient features and application characteristics of polyurethane roller

DESCRIPTION


The salient features and application characteristics of polyurethane roller:

 

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. It can adapt to various environments and humidity and temperature environments, high temperature and high humidity or severe cold and dry climate conditions.

 

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

 

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

 

4. Polyurethane roller 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. Especially it has good solvent resistance to boiling water, diesel oil, gasoline, lubricating oil, kerosene, toluene, alcohol and salt solution. But it is not resistant to acetone, ethyl acetate and strong acid and alkali. But it is not resistant to acetone, ethyl acetate and strong acid and alkali.

 

5. Polyurethane roller have excellent physical properties. Long-term use of roller 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. Experiments show that the tensile strength and wear resistance of polyurethane roller are 3 times and 5 times that of natural roller; the compression set and resilience are better; the service life of polyurethane roller is more than 3 times that of ordinary roller.

 

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

 

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