What rubber rollers wheels can we make?
1. NBR rubber roller:NBR rubber roller can be used as printing roller, food industry rubber roller, dyeing roller in textile printing in dustry and the soft rubber roller for contacting solvent and so on.
Note: The NBR has poor ozone resistance and the operation should be avoided in a high concentration ozone environment during processing.
2. Neoprene roller:Suitable for the soft printing roller, gravure printing roller and so on.
3. Silicone roller:High temperature resistance which can reach 200-250 degrees, and good chemical resistance,but it has low tensile strength.Silicone roller can be used in fabric heat setting, plastic heat setting embossing, calendering, photocopying and so on.
4.Polyurethane rubber:It has outstanding tensile strength wear resistance and crack resistance and good resistance to a variety of solvents.
5. Mirror roller:We generally adopt 45 # steel, alloy steel seamless pipe, precision forgings as the material.The surface of the roller finish degree can reach RA0.01. Mirror processing can ensure the roller surface flatness, balance, non-roundness, coaxial degree meet the customers'requirements.

What is rubber roller ?
Structure of bearing and shaft head inside the rubber roller is very precise, and a slight difference will directly affect the use effect. If lubrication of bearing and shaft head is not very good, it's easy to cause wear and seriously affect the quality of rubber roller, which will affect product quality.
Rubber rollers are widely used in textile, printing and dyeing machinery (rolling roller, printing machine rubber roller, coating rubber roller, setting machine rubber roller etc.), paper making,Plastic printing, packaging, industrial, wood, glass, steel metallurgy, tobacco, transportation and other equipment

Features and applications of PU rubber rollers wheels
Here are some basic introductions to PU Rubber rollers wheels:
1. Strong wear resistance: Polyurethane rubber has excellent wear resistance, allowing the rubber roller to resist friction and wear and maintain stable performance during long-term use.
2. Chemical stability: Polyurethane materials have good corrosion resistance to a variety of chemicals and solvents, allowing rubber rollers to operate stably for a long time in chemical and other environments.
3. Good elasticity and bending: Polyurethane rubber has good elasticity, which helps slow down shock and vibration, while its bending allows the roller to adapt to a variety of working conditions.
4. Low water absorption: The low water absorption of polyurethane rubber means that the rubber roller can maintain good performance in a humid environment and is not susceptible to moisture.
5. Good oil resistance: Polyurethane rubber has strong resistance to oil, making it excellent in application scenarios involving grease or lubricating oil.
6. Low noise level: The polyurethane rubber roller has a flat surface and low friction, so the noise generated during operation is relatively low, which helps to improve the comfort of the working environment.
7. Lightweight and high strength: Polyurethane material is relatively light but has high strength, which allows the rubber roller not only to reduce the equipment load, but also to withstand greater working pressure.
8. Easy to process and customize: Polyurethane materials are easy to process and shape, and rubber rollers can be customized according to specific needs to adapt to different equipment and process requirements.
Generally speaking, polyurethane rubber rollers have become an important component widely used in printing, packaging, chemical industry and other fields through their multiple characteristics such as wear resistance, chemical corrosion resistance, and elasticity.
