6 Main Features Of High-grade Rubber Rollers

First, the polyurethane rubber roller colloid has sufficient surface viscosity. Therefore, the rubber roller has good ink transfer property and inking performance during the printing process, and good ink affinity can ensure high-quality printing.

Second, it has excellent physical properties. It will not make the rubber roller hard and aging for a long time, and it has good tear resistance, resilience and excellent wear resistance. Long service life, easy to store, long-term storage will not affect the use effect. Natural rubber rubber rollers and synthetic rubber rollers are difficult to withstand the pressure, high-speed rotary machine, high temperature, high humidity production environment can run as usual without affecting (polyurethane rubber roller's tensile strength, abrasion resistance is natural rubber rubber 3 times to 5 times of the roller. Compression permanent deformation, resilience and abrasion resistance are better than those of synthetic rubber rubber rollers such as nitrile rubber rollers.

3. The high-grade rubber roller looks bright in appearance, the surface of the colloid is smooth and smooth, and the glue is firmly bonded to the core. The size of the rubber roller does not change greatly at different temperatures, and it can adapt to high temperature and high humidity environments or cold and dry climate conditions.

Fourth, the printing rubber roller has a good affinity for water: due to the special formula added to the polyurethane material, the molecular internal structure is changed, and a factor that has a good affinity for water is introduced and increased to improve the material's resistance to water Surface tension and surface water absorption, so it is used as dampening water, alcohol series rubber roller, the effect is very good.

Fifth, the printing rubber roller has excellent chemical properties and is suitable for various types of inks and printing methods. It is very suitable for varnishing rubber rollers and UV-type ink rubber rollers. (Especially good solvent resistance to diesel, gasoline, dampening oil, kerosene, saline solution, etc.)

6. High-grade rubber rollers are easy to clean. It is very easy to switch between dark and light color inks in production. As the master roll of some printing presses, it can remove the miscellaneous characteristics such as paper hair, dust and anti-stick powder spray on the printing plate, and does not require frequent loading and unloading cleaning To facilitate production.
