Red polyurethane rubber roller

The polyurethane rubber roller has a bright appearance, excellent wear resistance, corrosion resistance, good elasticity and tensile strength, accurate dimensions, and will not change greatly under different temperature and humidity conditions. As a printing rubber roller, it can be used freely in the high-temperature and high-humidity environment of the southern printing workshop or the severe cold and dry climate in the north. Because of its excellent characteristics, it is widely used in metallurgical industry, printing industry, paper glazing, printing iron glazing, oil glazing of other equipment and industrial applications with special requirements.
The polyurethane rubber roller has sufficient surface viscosity to ensure that the rubber roller has good ink transfer and inking performance during the printing process, and its good ink affinity can ensure the printing effect is rich in layers and high definition. In addition, polyurethane rubber rollers have high mechanical strength, excellent abrasion resistance, and outstanding compression resistance. They are suitable for all kinds of printing machinery and are the best partner for medium and high-end printing presses. They are unmatched by ordinary rubber rollers.
Polyurethane rubber rollers have stable chemical properties. Due to the special formula added to the polyurethane material, the introduction and increase of the extremely strong gene with good affinity to water improves the surface tension and surface water absorption of the material, and is used as a dampening plate. The water, alcohol rubber roller, the effect is excellent. Almost suitable for all types of inks and printing methods. And it has special natural resistance to solvent components in various inks, fountain solutions and cleaning agents. Polyurethane rubber rollers are also suitable for UV ink rubber rollers and varnished rubber rollers, etc., especially for boiling water, diesel, gasoline, lubricating oil, kerosene, toluene, alcohol and saline solution have good solvent resistance. But it is not resistant to acetone, ethyl acetate and strong acids and alkalis.
　　Polyurethane rubber roller has excellent physical properties: its hardness index is wide, from HS15 to HS90, which can meet the hardness requirements of different types of printing presses. Even if the rubber roller is used for a long time, it will not become hard and aging, and it has good tear resistance, resilience and excellent wear resistance, so it has a long service life and is easy to store. Long-term storage does not affect the use effect; the appearance and color of the polyurethane rubber roller Bright, the colloid surface is fine and smooth, and the colloid material and the mandrel are firmly bonded. It can withstand high pressure, high speed, high temperature and high humidity production environment. Experiments show that the tensile strength, shear resistance and abrasion resistance of polyurethane rubber rollers are 3 times and 5 times that of natural rubber rubber rollers; compression permanent deformation and resilience are better; the service life of polyurethane rubber rollers is 1 times that of general rubber rollers. Times more.
