# PU Belts vs. Plastic Belts: Key Differences and Applications
Both PU (polyurethane) belts and plastic belts are widely used in conveyor systems, but they serve different purposes based on their material properties.
## PU Belts
– Made from polyurethane, offering flexibility, durability, and resistance to oils, grease, and abrasion.
– Ideal for food processing, packaging, and light to medium-duty conveying.
– Available in various thicknesses and surface textures (smooth, rough, or patterned).
– Quieter and more resistant to stretching compared to rubber belts.
## Plastic Belts
– Typically made from thermoplastics like PP (polypropylene), PE (polyethylene), or PVC.
– Lightweight, chemical-resistant, and easy to clean, making them suitable for food, pharmaceutical, and washdown applications.
– Modular plastic belts allow for easy replacement and customization.
– Less flexible than PU but more rigid for heavy loads.
### Choosing the Right Belt
– Use PU belts for applications requiring flexibility and wear resistance.
– Opt for plastic belts when hygiene, chemical resistance, and modularity are priorities.
Both types enhance efficiency in material handling, but the best choice depends on the specific industry requirements.
