Advantages of Polyurethane Rollers

Advantages of polyurethane rollers

       1.Polyurethane rollers are made by casting process, compared with rubber rollers, it takes less time and the manufacturing cost is reduced a lot.

　　2.The rubber rollers have high surface viscosity, which can ensure good ink transfer and inking performance during the operation of the rollers, so as to guarantee high quality printing effect.

　　3.The rubber roller will not have great changes under different temperature and humidity conditions. It can adapt to the high temperature and high humidity environment of the printing workshop in the south and the cold and dry climate conditions in the north.

　　4.Good chemical performance, can adapt to different kinds of ink and printing methods. It has good resistance to the solvent in the ink, lubricant and cleaning agent.

　　5.The hardness index of polyurethane roller is wide, from HSA15 to HSD80, which can meet the hardness requirements of different types of printing machines.

　　6.The physical properties of polyurethane rollers are very good, even if used for a long time, it is not easy to harden and age, and the wear resistance, tear resistance and resilience are very good, so it has a long service life.

       7.The hydrophilicity of polyurethane roller is very good, so it can be used as water and alcohol wetting system roller.
