The Characteristics of Polyurethane Roller

The Characteristics of Polyurethane Roller

1. High strength, high pressure resistance, wear resistance and strong corrosion resistance

Moderately priced polyurethane PU rollers are widely used in metallurgy, papermaking, coal, wood processing, chemical fiber, textile, printing and other industries. There are a large number of applications on it, and its manufacturers have a good reputation.

2. High tear resistance

It is very resistant to shearing, and has a high gloss, the roller is bright in color, the surface of the colloid is smooth and fine, and the colloid material and the mandrel are firmly bonded. The quality-guaranteed polyurethane PU roller can show excellent strength, toughness and durability in various application fields, and can be used in different climates and environmental conditions. The product has stable and outstanding performance.

3. Good chemical properties

It can adapt to various types of inks and printing methods, and has unique resistance to solvent components in various inks, fountain solutions, and cleaning agents, but it is not resistant to acetone, ethyl acetate, and strong acids and alkalis.

4. Strong viscosity

The colloid used in the polyurethane PU roller has a strong surface viscosity, which can ensure that the roller has good ink transfer and ink holding performance in printing, and its good ink affinity can ensure high-quality printing. It has a wide range of hardness indicators, from HSA15 to HSD80, which can meet the hardness requirements of different types of printing machines for rollers.

All in all, the characteristics of polyurethane PU rollers are very prominent, and the price is moderate, and the service life is long. In order to make it fully effective, it is recommended to place the polyurethane PU roller outside for a period of time before use, which is more conducive to maintaining its relative stability, and can also increase the toughness of the colloid, thereby improving the durability effect.
