What is the difference between PE Tarpaulin and PVC Tarpaulin?

PE tarpaulin and PVC tarpaulin are both outdoor waterproof materials with a high frequency of use. Although they are all a kind of tarpaulin, there are significant differences in materials, production processes, features and application scenarios.

Different materials

PVC tarpaulin use high toughness polyester fabric as the base cloth. Both sides of the base cloth are coated with this PVC coating, which adds chemical additives such as anti-mildew agent, anti-aging agent and anti-static agent. In contrast, PE is a semi-crystalline thermoplastic material. The raw material of PE tarpaulin is usually HDPE (high-density polyethylene), which not only has a high application temperature, strength and impact toughness, but also has good chemical resistance.

Different production process

The production process of PE tarpaulin is relatively simple, which is to coat PE film on both sides of PE woven cloth. The process mainly includes drawing, round, weaving, double-sided coating. The production of PVC tarpaulin is more complex. It usually uses the impregnation technology, including straightening the raw material, coating the PVC, drying, cooling, cutting, and rolled. This process has high requirements for the purity of raw materials and process control, so the product purity of PVC cloth is also relatively high.

Different applications

The weight of PE tarpaulin is lighter than that of PVC tarpaulin, which makes it more suitable for construction site coverage, temporary stacking of goods. The PVC tarpaulin is more suitable for long-term outdoor use, such as truck covers, outdoor tents and so on, because of its excellent waterproof and anti-aging properties.

Conclusion

In summary, there are significant differences between PE tarpaulin and PVC tarpaulin in materials, production processes, features and applications. We should choose the most suitable according to the specific needs and use scenarios.
