Manufacturer Customized Polyurethane Roller for Metallurgical Steel Roller

1. Appearance is bright and glossy, with a dense and smooth colloid surface. The colloid material and shaft are securely bonded. The roller dimensions are strictly controlled, and there will be minimal variation in size under different temperature and humidity conditions. Capable of adapting to the high temperature and humidity environment in southern printing workshops and the severe cold and dry climate in northern regions.

2. Polyurethane roller hardness specifications are broad, ranging from HSA15 to HSD80, to meet the hardness requirements of different types of printing machines.

3. The colloidal material used in polyurethane roller has sufficient surface viscosity, ensuring excellent ink transfer and adhesion during the printing process, with its good ink-accepting properties guaranteeing high-quality printing.

4. Polyurethane roller exhibits excellent chemical properties, particularly good solvent resistance to diesel, gasoline, lubricants, kerosene, alcohols, and saltwater solutions.

5. Polyurethane roller features include physical properties that ensure long-term use without hardening or aging. It boasts excellent tear and resilience resistance, as well as good wear resistance, resulting in a longer service life, ease of storage, and no degradation in performance over time. It can withstand high-pressure, high-speed, and high-humidity production environments. Tests show that the tensile strength and wear resistance of polyurethane rollers are three and five times that of natural rubber rollers, respectively, with better resilience; their service life is over three times longer than that of standard rollers.
