Comparative Analysis of PVC and TPU Conveyor Belts
The Inbelts polyurethane conveyor belts offer an ideal solution for the safe and hygienic conveying of food and other industrial products. Over recent years, thermoplastic polyurethane (TPU) as a coating material for conveyor belts has made a strong impact on the conveyor and process belting market.
Difference Between TPU And PVC Conveyor Belts
The TPU belt has a higher Surface Hardness than PVC. But the PVC conveyor belts have large selection of patterns than TPU conveyor belts.
The Buring Smoke:
- TPU, Less Smoke, Color is White.
- PVC, Black Smoke.
The Raw Materials and Applications
For food industry, TPU conveyor belt is the first choice. TPU conveyor belt is made of thermoplastic polyurethane as the surface, being transparent, clean, non-toxic, and odorless, so it boasts almost all the characteristics Polyurethane (TPU) 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. TPU conveyor belts have been the first choice for many big names in the food industries, such as:
- candy
- pasta
- meat
- seafood
- baked goods
- Others
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. PVC belts can be used in many industries, and are widely used in:
- wood
- tobacco
- electronics
- logistics
- medicine
- packaging
- textile
- printing
- automobile and other industries.
