Owning many quality system certifications and patents, we can offer complete variety for texture roller coverings, and our rubber-coated roller tape product is diversified. By applying different materials and patterns on the surface, different surface characteristics can be realized, which can meet the requirements of different users on the soft, hard, and friction coefficient of the belt surface.
No deformation, No elongation
No stripping, Anti-Static
Wear-resistant, High-temperature resistance
Durable, Strong friction
For roller covering tape, accoring its different application in different industries, which will be made into different surface structures & made of various materials, such as polyethylene terephthalate(PET), Nitrile rubber (NBR), polyurethane(PU), silicone rubber(SR), and they will have totally different performances

Roller covering is used to increase the friction coefficient. It is usually used for fabric traction in different processes of textile industry, such as in various air-jet, water jet, rapier, shuttle looms, cloth inspection machines, cloth guide roller of finishing equipment after printing and dyeing, paper making equipment, etc.
Cause Analysis:
1. The raw rubber vinyl formula is unreasonable;
2. Too much dispersant;
3. The cold refining time is not enough, and the wettability of white carbon black and raw rubber is poor;
4. The cold refining temperature is high
Measures:
1. Add appropriate amount of polyvinyl silicone oil to increase the amount of vinyl (the most effective);
2. The dosage of dispersant should be appropriate;
3. After the white carbon black is eaten, it is refrigerated until it is extended for 45 minutes;
4. Ensure the cold refining temperature.
Cause Analysis:
1. No vinyl or too little vinyl;
2. Less or no vulcanizing agent or failure;
3. Low vulcanization temperature;
4. Short vulcanization time
Measures:
1. Add polyvinyl silicone oil or high vinyl raw rubber (the most effective);
2. Buy high-quality vulcanizing agent;
3. Appropriate vulcanization temperature;
4. Control the vulcanization time according to the thickness of the product
