1：The appearance is bright and glossy, with a dense and smooth colloid surface. The colloid material and core shaft are bonded firmly. The roller dimensions are strictly controlled, and there will be minimal variation in size under different temperature and humidity conditions.

2：Polyurethane roller features excellent physical properties; it won't harden or age with long-term use, and has good tear resistance, resilience, and wear resistance.SuperiorWithstanding high-pressure, high-speed, high-temperature, and high-humidity production environments. Tests show that the tensile strength and wear resistance of polyurethane roller tires are three and five times that of natural rubber roller tires, respectively; they also exhibit better compressive deformation and resilience. The service life of polyurethane roller tires is more than double that of regular roller tires.
