Pvc Knife Scraped Fabric For Heavy Duty Tarpaulins PVC Knife-Scraped Fabric for Heavy-Duty Tarpaulins
PVC knife-coated fabric (刀刮布) is a heavy-duty coated textile made by applying a thin PVC paste onto a polyester base fabric via knife scraping. This process gives exceptional coating uniformity. It is the gold standard for tarpaulins, truck side curtains, and architectural tent structures.

⚠ Industry note: PVC coated fabrics have no universal global model number. A specification like 1000D×1000D 30×30 / 1,050 gsm / FR is the correct format. Always specify denier + weave density + weight together — the same 1000D base with 20×20 vs 30×30 weave can differ by ~2× in tensile strength. All values are typical industry ranges — third-party test reports provided per batch.

Typical Applications
- Truck & trailer side curtains (Europe EN 12641-2)
- Container & lorry tarpaulins
- Scaffold enclosures & construction hoarding
- Industrial partitions & welding screens
- Event tents & marquees
- Agricultural covers (hay, straw, machinery)
How to Select the Right Specification
| European truck curtain |
1000D×1000D 30×30 / 1,050 gsm / FR (EN 12641-2) — min tensile ≥4,000 N/5cm @ 23°C, tear ≥300 N, peel ≥100 N/5cm |
| PVDF vs acrylic topcoat |
PVDF ≈ 2× price, 15–20 yr life (self-cleaning). Acrylic = 5–10 yr, lower cost. Always specify for outdoor |
| Spec both denier AND density |
Same "1000D" with 20×20 vs 30×30 weave can differ by ~2× in tensile. Never quote "1000D tarpaulin" alone |
Procurement Checklist
- Specify: tensile + tear + peel requirements, fire rating per local code, surface finish (PVDF/acrylic/matte), print ink compatibility
- All values are industry-typical ranges — we provide third-party lab test reports with every batch
- Import tariffs & anti-dumping change frequently — verify the latest WTO schedule before pricing
- Contact [email protected] with your spec requirements and target market for a quick quotation
