OEM Food Grade PVC PU Conveyor Belt for Automation Production Line Material Handling
PVC (Polyvinyl Chloride) and PU (Polyurethane) conveyor belts are the two most widely used synthetic conveyor belt solutions in modern industrial material handling. They are engineered with distinct material properties, performance characteristics, and application scenarios, serving as core components for efficient, reliable, and hygienic material transport across diverse sectors. Below is a comprehensive breakdown of their definitions, structures, features, applications, and key differences.
Basic Definition & Material Composition
PVC Conveyor Belt
A PVC conveyor belt is a flexible material-handling belt manufactured from polyvinyl chloride (PVC), a thermoplastic polymer resin, typically reinforced with polyester fabric plies as the structural skeleton. The PVC top/bottom cover layers are bonded to the polyester carcass via calendaring or extrusion processes, forming a robust, cost-effective belt structure.

|
Flexibility & Rigidity
|
Moderately flexible, more rigid than PU; suitable for straight or gentle-curve conveyors.
|
|
Abrasion Resistance
|
Good for general use, but inferior to PU (≈1/5–1/10 of PU’s wear life).
|
|
Temperature Resistance
|
Standard range: -10°C to +60°C; heat-resistant grades up to +80°C.
|
|
Chemical Resistance
|
Resistant to weak acids, alkalis, salts, and moisture; poor resistance to oils, greases, and strong solvents.
|
|
Hygiene & Cleanability
|
Smooth surface, easy to clean; non-food-grade standard; food-safe PVC grades available for dry food applications.
|
|
Cost
|
Highly cost-effective (≈30–50% cheaper than PU); low raw material and processing costs.
|
|
Maintenance
|
Low maintenance; easy to repair and splice; long service life in non-abrasive, dry environments.
|
PU Conveyor Belt
A PU conveyor belt is fabricated from polyurethane (PU), a versatile thermoset/thermoplastic elastomer with urethane linkages in its molecular structure. It can be produced via casting, extrusion, or injection molding, with options for single-layer solid PU or multi-layer designs with fabric reinforcement. PU belts are renowned for their elasticity, abrasion resistance, and food-grade compliance.
| Property |
Details |
| Flexibility & Elasticity |
High flexibility and elasticity; excellent for small pulleys, tight curves, and knife-edge transfers. |
| Abrasion Resistance |
Exceptional (5–10× higher than PVC); ideal for high-friction, heavy-abrasion applications. |
| Temperature Resistance |
Wider range: -30°C to +80°C; special grades up to +120°C; retains elasticity at low temperatures. |
| Chemical Resistance |
Excellent resistance to oils, greases, fats, weak chemicals, and solvents; ideal for oily food or industrial environments. |
| Hygiene & Cleanability |
Non-toxic, food-grade compliant (FDA, EU 1935/2004); seamless, non-porous surface; easy to disinfect; no bacterial growth. |
| Cost |
Higher upfront cost than PVC; justified by longer service life and performance in demanding applications. |
| Maintenance |
Low fraying; edge-sealed designs available; resistant to cuts and tears; longer replacement intervals. |
