The prominent advantages of PVC tarpaulin compared to Oxford cloth

Advantages of PVC Tarpaulin

PVC tarpaulin (polyvinyl chloride coated fabric) demonstrates remarkable advantages in various fields thanks to its unique chemical structure and manufacturing design.

1. Waterproof performance: 100% protection

The PVC tarpaulin forms a dense waterproof membrane through a high-density coating. Laboratory tests show that its waterproof level can reach 10,000 mm water column pressure, far exceeding the 3,000 - 5,000 mm standard of Oxford fabric. For instance, in logistics transportation, in rainy weather conditions, the PVC tarpaulin can ensure that the goods are completely dry within 72 hours, while the Oxford fabric, due to its breathable design, is prone to internal humidity accumulation and requires additional ventilation measures.

The PVC coated fabric further enhances its waterproof stability by adding UV inhibitors and flame retardants. For example, the PVC tarpaulin treated by the knife scraping process can have a thickness of up to 1.2 mm, and the heat sealing process at the seams can prevent needle eye leakage.

2. Resistance to Tear and Wear Resistance

The tensile strength of the PVC tarpaulin in the warp direction is ≥ 2000N/5cm, and its wear resistance (Martindearl test > 5000 times) is significantly better than that of Oxford fabric. In scenarios such as steel transportation and covering of port machinery, the PVC tarpaulin can withstand the long-term compression of 10 tons of steel without deformation, while the Oxford fabric will undergo irreversible deformation within 3 months under similar conditions.

Real case: A logistics company found through comparison that the PVC tarpaulin still maintains over 90% strength after repeated folding and friction, while the Oxford fabric will undergo irreversible deformation due to its low base fabric density and easily frayed edges.

3. Adaptability to harsh environments

The PVC tarpaulin has a temperature resistance range of -30°C to 70°C and is resistant to acidic and alkaline liquids as well as oil stains. It is suitable for use in chemical warehouses, sewage treatment plants, and other such scenarios. On the other hand, oxford cloth becomes soft at high temperatures and its coating is prone to flaking when exposed to ultraviolet rays for a long time. After 3 years, its strength decreases by 25%.

Special treatment: Through nano-coating technology, the PVC tarpaulin can be upgraded to a mold-resistant and antibacterial type, suitable for hygiene-sensitive areas such as food storage.

4. Economy: Short-term usage cost is lower

Although the unit price of the PVC tarpaulin is higher than that of the oxford cloth (about 20-50 yuan per square meter), its service life is 3-5 years, and the single-use cost is only one-third of that of the oxford cloth. For example, if a construction site uses PVC tarpaulins as dust covers, the annual replacement cost is more than 60% lower than that of the oxford cloth.

Typical application scenarios of PVC tarpaulins

1. Heavy-load transportation and industrial protection

The load-bearing capacity of PVC tarpaulins makes it the preferred choice for truck rain covers and mineral ore transportation covers. A steel enterprise's actual measurement shows that when PVC tarpaulins cover steel materials, even after experiencing heavy rain and heavy pressure, they can still maintain zero leakage.

2. Temporary buildings and disaster response

In exhibition venues, construction site warehouses, etc., PVC tarpaulins can quickly build rain and wind-proof spaces. Their flame-retardant properties (in accordance with EN13501 standards) can also be used for temporary fire isolation zones.

3. Ship and dock protection

The salt spray corrosion resistance of PVC tarpaulins makes it an ideal material for covering ship decks and protecting dock equipment. Its service life can reach over 5 years.
