Polyurethane rubber roller manufacturer; Hebei Silver Star

1. Appearance bright color, smooth fine colloid surface, colloidal material and the mandrel bonding firm. Cots strictly controlled size, size at different temperature and humidity conditions, there will be great changes. Able to adapt to the hot and humid southern pressroom environment and northern cold and dry weather conditions. 2. polyurethane rubber roller hardness index broadly, from HSA15 to HSD80, to meet different types of presses to rubber hardness requirements. 3. The polyurethane rubber roller with colloidal having sufficient surface viscosity can be guaranteed Cots good ink transfer and ink holdout in the printing process, the good performance of the pro-ink ensures high-quality printing. The polyurethane rubber roller good chemical resistance, suitable for all types of inks and printing methods. For various types of ink, fountain solution, washing solvent component has a special anti-resistance. Polyurethane rubber roller is also suitable for UV inks and coatings Cots Cots, especially for diesel fuel, gasoline, oil, kerosene, alcohol and saline solution have good solvent resistance. 5. The polyurethane rubber roller has excellent physical properties, long-term use of rubber roller will not harden, aging, and tear resistance, good resilience, excellent abrasion resistance, therefore long life, easy to save, not long-term storage affect the results; able to withstand high pressure, high speed, high humidity of the production environment. Experimental results show that the tensile strength of the polyurethane rubber roller, wear resistance is 3-fold and 5-fold natural rubber roller; compression set, good resilience; polyurethane rubber roller service life of more than three times the normal rubber roller.
