1：The appearance is bright and glossy, with a dense and smooth colloidal surface. The bonding between the colloidal material and mandrel is firm. The roller dimensions are strictly controlled, with minimal variation under different temperature and humidity conditions.

2：Polyurethane roller features excellent physical properties; it does not harden or age over long-term use, and boasts good tear resistance, resilience, and wear resistance.ExcellentWithstanding high-pressure, high-speed, high-temperature, and high-humidity production environments. Tests have shown that the tensile strength and wear resistance of polyurethane roller tires are superior to those of natural rubber roller tires.3X and 5X; good compression deformation and resilience; polyurethane roller has a lifespan over 1X that of a standard roller.
