| Polypropylene (PP) | 0.8–1.5 mm | 1,000–2,500 mm 39.4–98.4 in | Usually specified by the manufacturer; commonly selected in the medium-strength range for cage manure systems | Very good resistance to water, dilute acids, alkalis, and poultry-house chemicals | Approximately −10°C to 80°C 14°F to 176°F | About 3–8 years under proper tension, alignment, and cleaning conditions | Standard belt-type layer, broiler, and pullet cage systems | Good balance of flexibility, chemical resistance, weight, and cost |
| Polyvinyl Chloride (PVC) | 0.8–2.0 mm | 1,000–2,500 mm 39.4–98.4 in | Varies by reinforcement and belt construction; select a reinforced grade for long conveyors | Good resistance to moisture and many cleaning chemicals; performance depends on formulation | Approximately −10°C to 70°C 14°F to 158°F | About 2–6 years in normal poultry-house service | Short- and medium-length manure conveyors with moderate loading | Easy availability and smooth surfaces; avoid excessive heat and sharp mechanical damage |
| Polyethylene (PE) | 0.8–1.5 mm | 1,000–2,000 mm 39.4–78.7 in | Generally lower stiffness than reinforced PP or PVC belts | Excellent water resistance and good resistance to many agricultural chemicals | Approximately −30°C to 60°C −22°F to 140°F | About 2–5 years, depending on UV exposure and mechanical loading | Cold-climate installations and applications requiring good low-temperature flexibility | Confirm UV stabilization and abrasion resistance before outdoor or high-load use |
| Reinforced Polymer Belt | 1.2–2.0 mm | 1,000–2,500 mm 39.4–98.4 in | Higher tensile performance than unreinforced belts; exact value depends on reinforcement and construction | Very good when the polymer cover and reinforcement are properly sealed | Typically −10°C to 80°C 14°F to 176°F | About 5–10 years in demanding, well-maintained systems | Long runs, high bird density, frequent manure removal, and elevated loading | Preferred where reduced stretch, better tracking, and higher load capacity are priorities |
