PU conveyor belt is made of polyurethane as the surface, being transparent, clean, non-toxic, and odorless, so it boasts almost all the characteristics Polyurethane (PU) has. It is more elastic than rubber and more durable than metal, as well as being oil resistant, tear resistant, scratch resistance, and higher wear resistant. With so many superior characteristics, PU conveyor belts have been the first choice for many big names in the food industries, such as candy, pasta, meat, seafood, baked goods, etc., 

Pros

There are many benefits to choosing a PU conveyor belt for your business. Here are some significant ones:

  • High hardness and wear resistance. The Shore hardness of the PU conveyor belt can reach up to 92, which ensures it can convey some tough stuff, like metal parts.
  • Superior water and oil resistance, in contact with edible oil or mechanical oil, will not have a great impact on its service life, which explains why PU conveyor belt is widely used in the food industry.
  • They maintain stability and the conveyor belt rarely jumps with the vibration of the roller machine during use.
  • Food-grade safety, PU conveyor belt qualified by FDA has a wide range of applications in the food and pharmaceutical industries.
  • Better performance to adapt to the range of temperature of the working environment.

Cons

Although there are not many disadvantages to share, there are indeed a few problems with PU conveyor belts:

  • Fragile, they have a probability of getting broken when fail to distribute pressure evenly.
  • With poor mechanical strength, PU conveyor belts share a poor ability to resist deformation, tension, and torsion. So they are usually used to convey light products.
  • The acid and alkali resistance of PU conveyor belts is relatively weak, compared with PVC ones
  • Higher budget. PU conveyor belts comparatively cost more than PVC belts.

Industries Prefer PU Conveyor Belt

Many industries have to put the safety of products in front of any other factors when it comes to building a production line, such as food, cosmetic and skincare products, medicine, tobacco, chemical, and other industries.

  • Tobacco Industry
  • Medicine Industry

PVC conveyor belt is made of pure natural polyvinyl chloride with high-strength and high-quality cotton, nylon, and polyester canvas as the core, wildly used to convey small and medium-sized pieces, powders, and granular materials. It is optimum for material transportation under short and medium distance conditions, with operating temperatures from -10° to +80°, and can be used in many industries. PVC conveyor belts are easily available at a lower price when considering them for your production line or business.

Pros

  • PVC conveyor belts have been cost-competitive
  • Easy to clean and maintain.
  • Superior lateral stability to avoid the deviation of production lines.
  • Certain ability to resist weak acid and alkali extends their working life.
  • Various color options to meet the needs of different application conditions

Cons

  • With poor oil resistance, PVC conveyor belts can be corrupted when in contact with water and oil constantly.
  • They are fragile at low temperatures and easy to break
  • PVC conveyor belts share a shorter service life than PU ones.

Industries Prefer PVC Industries 

PVC belts are wildly used to convey small and medium-sized pieces, powders, and granular materials. It is optimum for industries like the logistics industry, printing industry, wood industry, entertainment industry, stone industry, etc.

  • Transportation of Stones and Sands
  • Logistics Sorting
  • Package Transportation

Though PVC belts share a lower level of safety, they are still possible to be employed in food industries. There are uncountable food and beverage packages transported with PVC conveyor belts. 

By completely knowing the characteristics of PU and PVC conveyor belts, we can find a guide to make better decisions. Starting from the industry you root in, if there is no requirement for food-grade safety in production, you can put any other factors in the first place.
