The 3M Millennium Roller is composed of high-strength artificial woven fibers that exhibit self-healing properties at specific temperatures, humidity, and pressures. Its porous non-woven structure boasts water and oil absorption characteristics, making it more effective at drying residual water and oil on the roll surface compared to traditional rubber rollers. Additionally, due to its porosity, fine debris and contaminants on the roll surface are less likely to adhere to the outer layer, instead penetrating into the non-woven structure, thus preventing scratches and contamination of the roll.

Furthermore, the 3M Millennium Roller boasts characteristics that traditional rubber and steel rollers lack, such as a high coefficient of friction. This feature provides ample friction, effectively preventing slippage of the roller and avoiding secondary scratches on the material surface. This characteristic, when applied to the tension roller of the 3M Millennium Roller, offers even greater tensioning power.
