Characteristics and application of good price and quality Polyurethane Rollers from China manufacturer

Good price and quality Polyurethane Rollers from China manufacturer are simply a kind of rubber roller made of chemical materials. It is very popular because of its many advantages. So, what are the specific characteristics and uses of polyurethane roll products?

1. Good price and quality Polyurethane Rollers from China manufacturer has excellent hydrophilicity, so it can be used as rubber roller of water and alcohol fountain system.  

2. Good price and quality Polyurethane Rollers from China manufacturer has high strength and tear resistance, so it is shear resistant and wear-resistant.  

3. The hardness index of good price and quality Polyurethane Rollers from China manufacturer is broad, from hsa15 to hsd80, which can meet the requirements of different types of printing presses for the hardness of cots.  

4. The good price and quality Polyurethane Rollers from China manufacturer has sufficient surface viscosity, which can ensure that the rubber roller has good ink transfer and inking performance in the printing process, and its good inkfriendly performance can ensure high-quality printing.  

5. The appearance of good price and quality Polyurethane Rollers from China manufacturer 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 various environments, humidity and temperature environments, high temperature, high humidity or severe cold and dry climatic conditions.  

6.Good price and quality Polyurethane Rollers from China manufacturer has good chemical properties and is suitable for various types of inks and printing methods. It has special resistance to solvent components in various inks, fountain solutions and cleaning agents. In particular, it has good solvent resistance to boiling water, diesel, gasoline, lubricating oil, kerosene, toluene, alcohol and brine solutions. But it is not resistant to acetone, ethyl acetate and strong acid and alkali. But it is not resistant to acetone, ethyl acetate and strong acid and alkali.

7. Good price and quality Polyurethane Rollers from China manufacturer has excellent physical properties. The rubber roller will not harden and age after long-term use, and has good tear resistance, rebound performance and excellent wear resistance. Therefore, it has long service life and is 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 polyurethane cots are 3 and 5 times higher than those of natural rubber cots; Good compression set and resilience; The service life of polyurethane cots is more than 3 times that of ordinary cots.
