Rubber rollers: hydrogenated nitrile rubber rollers, polyurethane rubber rollers, carbon fiber rollers, composite material rubber rollers, EPDM rubber rollers, silicone rubber rollers, fluororubber rollers, butyl rubber rollers, natural rubber rollers, chloroprene rubber rollers, wool rollers, oil extrusion rollers, anodized aluminum rollers, functional rollers, etc;
Various types of rollers are widely used in industries such as lithium batteries, aluminum processing, metallurgy, papermaking, packaging, leather, printing and dyeing, textiles, films, plastics, and construction machinery. It can meet customers' requirements for wear resistance, high temperature resistance, oil resistance, solvent resistance, high pressure resistance, high speed, acid and alkali resistance, and can be customized according to drawings and samples.

1. Excellent wear resistance

The wear resistance of polyurethane is about 3-5 times that of natural rubber, making it suitable for high friction environments (such as printing and papermaking machinery) and significantly extending its service life.

2. High elasticity and tear resistance

Wide range of elastic modulus (Shore A50-A96), customizable softness and hardness, strong absorption of impact force, and avoidance of equipment vibration damage.

3. Oil resistance and chemical stability

Has good resistance to mineral oil, solvents (such as gasoline, lubricants), and weak acids and bases, suitable for chemical and ink environments.

4. Wide temperature adaptability

The working temperature range is usually -30 ℃ to+80 ℃, and some modified formulations can reach up to 120 ℃, which is better than most rubber materials.

5. Flexible customized design

Different hardness, color, conductivity and other requirements can be met by adjusting raw materials (such as TDI/MDI/PPD system) and processes (casting/hot pressing).

Main application areas

Steel and Metal Processing/Printing Industry/Paper and Packaging/Textile Printing and Dyeing/Steel and Metal Processing/Plastic Film and Electronics Industry/Other Industrial Fields

For example, the aluminum foil rolling mill, slitting machine, rewinding machine, and flattening roller on the rewinding machine during the aluminum foil processing; Support rollers and working rollers for cold rolling and hot rolling processes, transmission rollers for pickling lines, coating rollers for galvanizing/color coating lines, straightening rollers for straightening machines, and guide rollers for slitting machines;

Ink transfer rollers and ink equalization rollers for offset printing machines, embossing rollers and back pressure rollers for gravure printing machines, coating rollers and transfer rollers for composite machines, tension control rollers and correction rollers for slitting machines, etc

Polyurethane rubber rollers are gradually replacing traditional metal and rubber rollers and becoming the preferred component for high-precision industrial equipment through continuous improvement in material science, such as nanofiller reinforcement. When selecting, it is necessary to consult professional manufacturers for material optimization based on specific working conditions.
