Which one is better, PVC conveyor belt or PU conveyor belt？

PVC and PU conveyor belts each have their own characteristics and applicable scenarios, and it is impossible to simply say which one is better. The following compares the two conveyor belts from different angles:

Acid and alkali resistance: PVC conveyor belts are relatively resistant to acids and alkalis, so they are often used in the production and transportation of chemical raw materials. PU conveyor belts are slightly inferior in acid and alkali resistance, but have advantages in other aspects.
Oil resistance: PU conveyor belts have strong oil resistance, so PU conveyor belts are widely used in environments with more edible oil and machine oil.
Hardness and impact resistance: PU conveyor belts have a higher hardness, generally at 92 Shore hardness, while PVC conveyor belts have a relatively low hardness, generally around 80-86 degrees. This makes PU conveyor belts better in terms of cut resistance and impact resistance.
Food grade requirements: For food transportation, PU conveyor belts are more popular. Its surface is transparent, clean, non-toxic and tasteless, and can be directly in contact with food. And if there is leakage due to the machine, it can also be recycled. The PU conveyor belt is thinner overall, and the conveyor belt has strong tension, which meets FDA food grade certification.
Price and cost-effectiveness: If the goods being transported are not food, PVC conveyor belts are more cost-effective. They are strong, light, have a long service life, and are relatively more economical.
Application range: PVC conveyor belts have a wide range of applications, especially in transportation lines with slopes, where the guide strips and skirt baffles can be processed. PU conveyor belts are mostly used in the food industry.
In summary, the choice of which conveyor belt is better depends mainly on the specific usage scenario and needs. If used for food transportation or in situations with high food grade requirements, PU conveyor belts may be more suitable; in other non-food transportation scenarios, PVC conveyor belts may be more cost-effective.
