What are the characteristics and uses of PU rubber roller products

PU rubber roller products are familiar to many friends. This emerging plastic tool has become a leader in the plastic market. What are the characteristics and uses of PU rubber roller products?

1. The appearance of PU rubber roller products is bright, the colloidal surface is fine and smooth, and the colloidal material is firmly bonded to the mandrel. The size of COTS is strictly controlled, and the size will not change greatly under different temperature and humidity conditions. It can adapt to the high temperature and humidity environment of the printing workshop in the South and the cold and dry climate conditions in the north.

2. PU rubber roller products have a wide range of hardness indicators, from hsa15 to hsd80, which can meet the hardness requirements of different types of printing presses.

3. PU rubber roller products have excellent physical properties. They will not harden and age after long-term use, and have good tear resistance, resilience and wear resistance. Therefore, they have long service life and are easy to store. Long term storage will not affect the use effect; Able to withstand high pressure, high speed and high humidity production environment. The results show that the tensile strength and wear resistance of PU rubber roller products are 3 and 5 times higher than those of natural rubber cots; Good compression deformation and resilience; The service life of PU rubber roller is more than 3 times that of ordinary cots

4. PU rubber roller products have excellent hydrophilicity, so they can be used as cots in water and alcohol fountain system.

5. PU rubber roller products have high strength and tear resistance, so they are shear resistant and wear-resistant.

6. The colloid used for PU rubber roller products has sufficient surface viscosity, which can ensure that the cots have good ink transfer and inking performance in the printing process, and its good ink affinity can ensure high-quality printing.

PU rubber roller products  have good chemical properties and are mainly used in the following two aspects:

First PU rubber roller products can be used in textile industry to improve textile efficiency. PU rubber roller products can be used in the textile field. Its surface is very smooth, which can effectively solve a major problem in the textile industry. When spinning, it is easy to wind between lines. If PU rubber roller products are used, the lines can not only be wound on the cots orderly, but also be taken out quickly when the lines need to be used. Therefore, many textile industries need this kind of cots.

Second PU rubber roller products also play a very important role in the printing industry and can adapt to various printing presses and different printing methods. PU rubber roller products not only have smooth surface, but also have a certain degree of viscosity. This can meet the needs of the printing industry. Because printing needs the help of a variety of printing machines, PU rubber roller products can well meet the hardness requirements of each printing machine, and the surface viscosity can make the ink printing clearer.
