1.The appearance is bright in color, the colloid surface is fine and smooth, and the colloid material and the mandrel are firmly bonded. The size of the rubber roller is strictly controlled, and the size will not change greatly under different temperature and humidity conditions.
2.Polyurethane rubber rollers have a wide range of hardness indicators, from HS15 to HS90, which can meet the hardness requirements of different types of printers.
3.The colloid for polyurethane rubber rollers has sufficient surface viscosity to ensure that the rubber rollers have good ink transfer and inking properties during the printing process. Its good ink affinity can ensure high-quality printing.
4.Polyurethane rubber rollers have good chemical properties and are suitable for various types of inks and printing methods. It has special 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.
5.Polyurethane rubber rollers have excellent physical properties. The rubber rollers will not become hard and aging after long-term use, and they have good tear resistance, resilience and excellent wear resistance, so they have a long service life and are easy to store. Long-term storage will not affect use. Effect; able to withstand high pressure, high speed, high temperature, high humidity production environment. Experiments show that the tensile strength and abrasion resistance of polyurethane rubber rollers are 3 times and 5 times that of natural rubber rubber rollers; the compression permanent deformation and resilience are better; the service life of polyurethane rubber rollers is more than 1 times that of general rubber rollers.
6.Polyurethane rubber roller has excellent hydrophilicity, so it can be used as water and alcohol dampening system rubber roller with good effect.
7.The polyurethane rubber roller is easy to clean, easy to carry out the conversion of dark and light inks, which is convenient for printing and color changing.
As a professional manufacturer of polyurethane rubber rollers, Jinan Power Roller equipment Co.,Ltd is not only serious and rigorous in terms of production quality, but also superb and advanced in technology.
