The Characteristics of Polyurethane Rollers

The Characteristics of Polyurethane Rollers

1. The color of the roller is bright from the appearance, the surface of the colloid is fine and smooth, and the glue and the core are firmly bonded. The size of the roller will not change greatly at different temperatures, and it can adapt to high temperature and high humidity environment or severe cold and dry climate.

2. Polyurethane roller colloid has sufficient surface viscosity. Therefore, the rollers has good ink transfer and ink holding performance during the printing process, and good ink affinity can ensure high-quality printing.

3. It has excellent chemical properties and is suitable for various types of inks and printing methods. It is very suitable for UV ink rollerss and varnish rollerss. (Especially good solvent resistance to diesel, gasoline, dampening oil, kerosene, salt water solution, etc.)

4. It has excellent physical properties, long-term use will not make the rollers hard and aging, and it has good tear resistance, rebound performance, and excellent wear resistance. Long service life, easy storage, long-term storage does not affect the use effect. Under the unbearable pressure of natural rollerss and synthetic rollerss, high-speed rotary machines, high-temperature, high-humidity production environments, it can still operate as usual without affecting it (the tensile strength and wear resistance of Polyurethane rollers are lower than those of natural rubber rubber. 3 times to 5 times that of rollers. Compression permanent deformation, resilience and wear resistance are better than synthetic rollerss (such as nitrile rollerss, etc.).

5. Because the special formula is added to the polyurethane material, its molecular internal structure is changed, and a very strong gene with good affinity for water is introduced and increased, thus improving the surface tension resistance and surface water absorption of the material to water. Therefore, the water and alcohol series rollerss used as dampening plates have excellent effects.

6. The rollers is easy to clean. It is very easy to switch between dark and light inks in production. As the backing roller of some printing machines, it can stick to the miscellaneous characteristics such as paper wool, dust and anti-adhesive sheet powder spraying on the printing plate, and does not require frequent loading and unloading cleaning. , to facilitate production.
