PU Flat Conveyor Belts

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

1. 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.

2. Basic Technical Specifications

All specifications for the PU Flat Conveyor Belt can be fully customized to match each production line’s operating requirements.

3. 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.

4. 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.

5. 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.
