Smooth PU conveyor belts — also known in many industries as PU Flat Conveyor Belts are widely used across applications requiring strict hygiene standards, durability, and high operational efficiency. With an ultra-smooth polyurethane (PU) surface and a flat, non-embossed structure, the PU Flat Conveyor Belt ensures gentle, clean product transportation while meeting stringent requirements in food processing, pharmaceuticals, electronics, textiles, and other precision-driven sectors.
Key Features of PU Flat Conveyor Belts
Structure
A PU Flat Conveyor Belt is typically constructed from multiple layers, with each layer optimized for tensile strength, load capacity, flexibility, and longevity:
-
Top Surface Layer (PU Coating): Pure polyurethane with a smooth, non-stick, hygienic finish that is antibacterial and easy to clean.
-
Tension Layer (Fabric Ply): Typically, a polyester material that enhances tensile strength and minimizes elongation.
-
Bottom Layer: Protects the fabric and increases abrasion resistance during roller and pulley contact.

Basic Technical Specifications
| Feature | Specification |
|---|---|
| Belt Thickness | 0.8mm – 3.0mm |
| Fabric Layers | 1 – 3 Polyester Plies |
| Belt Width | 200mm – 2000mm (customizable) |
| Belt Length | 1m – 30m |
| Surface Hardness | 85 – 95 Shore A |
| Operating Speed | Up to 60 m/min |
| Working Temperature | -20°C to 80°C (short-term up to 100°C) |
| Anti-Static Feature | Optional (for electronics sector) |
| Common Colors | White, Blue, Green, Black |
All specifications for the PU Flat Conveyor Belt can be fully customized to match each production line’s operating requirements.

Load Capacity & Operating Speed
Smooth PU conveyor belts and PU Flat Conveyor Belts support load capacities from 50 kg/m to 200 kg/m, suitable for light to medium-duty applications. Operating speed ranges between 5 m/min and 60 m/min, compatible with continuous and automated systems.

Heat Resistance & Chemical Resistance
The PU Flat Conveyor Belt operates reliably within -20°C to 80°C, with certain enhanced versions capable of tolerating up to 100°C short-term. They offer strong resistance to oils, mild acids, solvents, and cleaning chemicals, maintaining long-term performance in demanding production conditions.
Mechanical Strength & Abrasion Resistance
Thanks to high-quality PU and reinforced fabric layers, smooth PU belts provide:
- Excellent tensile strength
- High tear resistance
- Strong abrasion durability
Typical lifespan ranges from 3 to 5 years, depending on application and maintenance.
