Polyurethane Roll

It is a kind of hard stick with enough surface viscosity for printing. It can ensure that the cots have good ink transfer and inking performance in the printing process. Its good ink affinity can ensure high quality printing.

Material: Polyurethane

Structural parameters
Polyurethane cots have a wide range of hardness indicators, ranging from HSA15 to HSD80, which can meet the requirements of different types of printers for cots hardness.

Applicable occasions
Mechanical and industrial printing. In offset printing technology, the key is to control the balance between water and ink, and ink balance depends on the key components of cots and ink rollers, whose quality can directly affect the quality of products. Gravure, embossing and flexo printing are all the more so.

Characteristic:

1. The appearance of the colloid is bright, the surface of the colloid is fine and smooth, and the colloid material and the core axle are firmly bonded. Strict Control of Cot Size.The size will not change greatly under different temperature and humidity conditions. It can adapt to the high temperature and humidity environment of the southern printing workshop and the cold and dry climate conditions of the north.

2. Polyurethane cots have a wide range of hardness indicators, ranging from HSA15 to HSD80, which can meet the requirements of different types of printers for cots hardness.

3. Polyurethane cots colloid has enough surface viscosity to ensure that cots have good ink transfer and inking performance in the printing process, and good ink affinity can ensure high quality printing.

4. Polyurethane cots have good chemical properties, especially for diesel oil, gasoline, lubricating oil, kerosene, alcohol and brine solution.

5. Polyurethane cots have excellent physical properties, long-term use of COTS will not harden, aging, and tear resistance, resilience, excellent wear resistance, so long service life, easy to preserve, long-term storage does not affect the use effect; can withstand high pressure, high speed, high humidity production environment. Experiments show that the tensile strength and wear resistance of polyurethane cots are 3 and 5 times of that of natural rubber cots, the compression permanent deformation and resilience are good, and the service life of polyurethane cots is more than 3 times of that of ordinary cots.

Specification parameters: 45mm * 55mm * 8mm * 15mm (unit: mm), can be customized production.
