What are the main performance characteristics of high-quality PU rubber roller products with moderate price?

PU rubber roller products are mainly used as various printing machines such as printing machines and one of the important accessories that play a key role in the quality of their printing products. For high-quality printing machines, quality PU rubber roller with guaranteed quality should be configured for use, so as to ensure that the quality of the produced printing products is good enough. So, what are the main performance characteristics of PU rubber roller with moderate price?

1、 Good adaptability. The overall appearance of PU rubber roller is bright and its colloidal surface is fine and smooth. Due to the strict control of the size of PU rubber roller, the size of the rubber stick will not change greatly under different temperature and humidity environments. At the same time, it can adapt to the environmental conditions of high temperature and humidity in the South and cold and dry in the north.

2、 Good hardness and viscosity. The hardness index of PU rubber roller is relatively broad, which can meet the requirements of different printing machine models for the overall hardness of the rubber stick. At the same time, because the surface material of PU rubber roller has sufficient viscosity, it can ensure that the rubber stick has good ink transfer and inking performance and achieve high-quality printing effect in the printing process.

3、 Good chemical properties. PU rubber roller products have good chemical properties. They can play a special role in resistance to various inks, fountain solutions and solvent components in cleaning solutions. They also have excellent solvent resistance to boiling water, kerosene and gasoline solutions, and can be well matched to various types of inks and printing methods.

4、 Excellent physical performance. PU rubber roller have excellent physical properties, so that they will not age and harden after long-term use, and also have excellent wear resistance, tear resistance and good resilience, so that PU rubber roller products are easier to preserve and do not affect their use effect.

The above content is the main performance characteristics of PU rubber roller products with moderate price. In addition to the performance characteristics mentioned in the above four points, quality PU rubber roller also have excellent hydrophilic properties, so they can be used as glue sticks of water or alcohol fountain system. At the same time, due to the easy cleaning characteristics of PU rubber roller, they can convert dark and light ink during printing operation.
