Application Characteristics of Polyurethane Coated Rollers

Application Characteristics of Polyurethane Coated Rollers:

1. The appearance is bright in color, the surface of the colloid is dense and smooth, and the colloid material and the mandrel are firmly bonded. The size of the drum will be strictly controlled and will not change greatly due to temperature and humidity conditions.

2. The hardness index of polyurethane coated rollers ranges from HSA15 to HSD80, which can meet the hardness requirements of different types of printers.

3. Polyurethane rubber-coated roller has sufficient surface viscosity, and its good ink affinity can ensure high-quality printing, and can ensure good ink transfer and ink adhesion performance in rubber roller printing.

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

5. Polyurethane rubber-covered rollers have excellent physical properties, good wear resistance, and are easy to store for a long life. They are wear-resistant in high-pressure, high-speed, and high-humidity production environment tests that do not affect the use effect for a long time. The rubber rollers used for a long time will neither harden nor age. In addition, they have good tear resistance and resilience.

6. Polyurethane rubber-coated rollers have excellent hydrophilicity and can be used as water-based or alcohol-wetted rubber.

7. The high strength, high crack resistance, shear resistance and excellent wear resistance of polyurethane rubber-covered rollers.
