1.The appearance is glossy with a fine and smooth colloidal surface. The colloidal material and core shaft are firmly bonded. The roller dimensions are strictly controlled, with minimal changes in size under varying temperatures and humidity conditions. It is capable of adapting to the high temperature and humidity environment of southern printing workshops as well as the severe cold and dry climate of northern regions.
2.Polyurethane roller hardness specifications are broad, ranging fromHSA15Please provide the Chinese content to be translated.HSD80,Meets the hardness requirements for rubber rollers for various types of printing machines.
3.The colloidal adhesive used in polyurethane roller has sufficient surface viscosity, ensuring excellent ink transfer and adhesion during the printing process, and its good ink-accepting properties guarantee high-quality printing.
4.Polyurethane roller exhibits excellent chemical properties, particularly good solvent resistance to diesel, gasoline, lubricating oil, kerosene, alcohols, and saltwater solutions.
5.Polyurethane roller has excellent physical properties; it does not harden or age over long-term use, and boasts good tear resistance, resilience, and wear resistance. As a result, it has a long service life, is easy to store, and long-term storage does not affect its performance; it can withstand high-pressure, high-speed, and high-humidity production environments. Experiments show that the tensile strength and wear resistance of polyurethane roller are superior to those of natural rubber rollers.3Beihuo5The company's new product features a compression deformation and good resilience; the polyurethane roller has a lifespan that is twice that of a standard roller.3Please provide the Chinese content to be translated.
6.Polyurethane roller boasts excellent hydrophilic properties, making it suitable for use as water and alcohol sizing system rollers.
7.Polyurethane roller features high strength and excellent tear resistance, hence its durability against shearing and abrasion.
