| Property | Details |
|---|---|
| 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 |
| 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 |
| Feature | PVC Belt | PU Belt |
|---|---|---|
| Primary Material | Polyvinyl Chloride | Polyurethane |
| Key Characteristics | Good durability, cost-effective, water-resistant, wide range of colors/patterns | Excellent abrasion & cut resistance, high flexibility, oil/grease resistant, FDA-approved options available |
| Surface Texture | Can vary from smooth to highly textured (cleated, rough top) | Often very smooth and non-porous, also available in textured versions |
| Operating Temperature | Moderate range (approx. -10°C to +80°C) | Slightly wider range than PVC, but can degrade at very high temperatures |
| Flexibility | Stiff to moderately flexible, depending on ply count | Highly flexible, even at low temperatures; excellent for small pulley drives |
| Chemical Resistance | Good resistance to water, acids, alkalis | Superior resistance to oils, greases, and many solvents |
| Typical Applications | Package handling, light assembly, agriculture, baggage handling, general conveying | Food processing (slicing, washing, packaging), precision manufacturing, timber, recycling, steep incline conveying |
