PU vs PVC Conveyor Belt


PU vs PVC Conveyor Belt

Comprehensive comparison of Polyurethane (PU) and Polyvinyl Chloride (PVC) conveyor belts: characteristics, advantages, disadvantages, and suitable applications.

PU Conveyor Belt (Polyurethane)

PU conveyor belts are made from polyurethane material, offering excellent wear resistance, oil resistance, and mechanical properties.

Key Features:

  • Excellent abrasion and tear resistance
  • Good oil and chemical resistance
  • High tensile strength and mechanical properties
  • Good anti-microbial properties
  • Complies with food-grade standards (selected models)
  • Operating temperature range: -30°C to 80°C

Advantages:

  • Long service life, low maintenance cost
  • Suitable for heavy-duty and high-speed applications
  • Easy to clean, meets hygiene standards
  • Good anti-static properties

Disadvantages:

  • Higher cost compared to PVC conveyor belts
  • Sensitive to certain chemicals
  • Performance may decrease in high-temperature environments

PVC Conveyor Belt (Polyvinyl Chloride)

PVC conveyor belts are made from polyvinyl chloride material, offering a cost-effective conveyor belt solution.

Key Features:

  • Good abrasion resistance and flexibility
  • Excellent waterproof and moisture-resistant properties
  • Cost-effective
  • Available in various thicknesses and surface textures
  • Operating temperature range: -10°C to 70°C

Advantages:

  • Affordable price, good cost-performance ratio
  • Easy to process and install
  • Good acid and alkali resistance
  • Available in various colors for production line identification

Disadvantages:

  • Poor oil resistance
  • Becomes stiff in low-temperature environments
  • Relatively shorter service life
  • Average environmental performance
