Difference Between Nylon (PA) & Polypropylene (PP) Bird Netting

1. Raw Material Core Property

Polypropylene (PP, our factory’s main material)

- Low density, much lighter weight. Same size net weighs 30%~45% less than nylon.

- Inert to acid & alkaline farm soil, fertilizer, pesticide. No corrosion from farm chemicals.

- Low water absorption: almost no water intake, won’t get heavier after rain.

Nylon (PA Nylon)

- High density, heavier physical weight.

- Absorbs water obviously, tensile strength drops around 15% after soaking in rainwater.

- Weak against acid; long-term contact with farm fertilizer will accelerate aging.

2. Outdoor Anti-UV & Service Life

- PP Net: We can add UV masterbatch during extrusion molding. With stabilized UV formula, outdoor service life reaches 3–5 years. Extruded knot structure locks UV additive firmly.

- Nylon Net: Nylon itself degrades rapidly under strong sunlight. Even with UV coating, outdoor lifespan is only 1–2 years; UV coating wears off quickly.

Conclusion: PP performs far better for long-term open-air farm use.

3. Tensile Strength & Structure Stability

- PP Extruded Bird Net (our product): Fused solid knots, mesh shape fixed permanently. No mesh shift, no unraveling even under strong wind or bird pecking.

- Nylon Net: Mostly woven structure. Knots slide easily under pulling force; meshes deform, birds can squeeze through deformed holes. Nylon gains slight stretch when wet, further distorting meshes.

4. Price & Cost Performance

- PP raw material cost is lower than nylon. For large farm bulk orders, PP net cuts total project cost greatly without sacrificing protective effect.

- Nylon raw material is expensive, final finished price is 40%+ higher than PP net. Not cost-efficient for large-area farm covering.

5. Application Scenarios Split

Best for PP Bird Net :

Large orchards, crop farms, greenhouses, aquaculture anti-bird, long-term outdoor agricultural bulk use.

Nylon Net Applicable Scenarios:

Short-period indoor use, fishing net, temporary short-term enclosure; rarely used for long-term farm anti-bird projects.
