Uses and characteristics of polyurethane rubber roller

1. The appearance of bright color, fine and smooth surface colloid, colloidal material and the mandrel bonding firm. Cots strictly controlled size, size at different temperatures and humidity conditions, there will be great changes. Able to adapt to the South pressroom hot and humid environment and northern cold and dry weather conditions.

2. polyurethane rubber roller hardness index broadly, from HSA15 to HSD80, to meet different types of presses to rubber hardness requirements.

3. polyurethane rubber roller with colloidal surface with sufficient viscosity can be guaranteed Cots good ink transfer and ink performance in the printing process, the ink receptive good performance can be guaranteed high-quality printing.

4. Good polyurethane rubber roller chemical properties, suitable for all types of inks and printing methods. For various types of ink, fountain solution, washing solvent component has a special anti-resistance. Polyurethane rubber roller is also suitable for UV inks and coatings Cots Cots, especially for diesel fuel, gasoline, oil, kerosene, alcohol and saline solution have good solvent resistance.

5. The polyurethane rubber roller has excellent physical properties, long-term use rubber roller will not harden, aging, and tear resistance, good resilience, excellent wear resistance, therefore long life, easy to save, not long-term storage affect the results; can withstand high pressure, high speed, high humidity production environment. Experimental results show that the tensile strength of polyurethane rubber roller, wear resistance is 3 and 5 times natural rubber roller; compression set, good resilience; polyurethane rubber roller is more than three times the normal service life of rubber roller.

6. The polyurethane rubber roller has excellent hydrophilic, it can be used as water, alcohol dampening systems use rubber roller.

7. The polyurethane rubber roller with high strength, high tear resistance, resistance to shear, wear.
