Hey there! I'm a supplier of PVC tarpaulins, and I often get asked about the differences between PVC tarpaulin and canvas tarpaulin. So, I thought I'd write a blog post to share what I know.
Material Composition
First off, let's talk about the materials. PVC tarpaulin is made from Polyvinyl Chloride, a synthetic plastic polymer. It's created by coating a polyester or nylon scrim with PVC compounds. This makes it highly resistant to water, UV rays, and chemicals.
On the other hand, canvas tarpaulin is typically made from cotton or linen, which are natural fibers. These fibers are woven together to form a strong, durable fabric. But compared to PVC, canvas is more porous and less resistant to water and chemicals right out of the box.
Durability
When it comes to durability, PVC tarpaulin has a clear edge. The synthetic nature of PVC means it's less likely to rot, mildew, or fade over time. The PVC coating acts as a protective layer, shielding the inner fabric from environmental elements. It can withstand harsh weather conditions like heavy rain, strong winds, and intense sunlight without losing its shape or integrity.
Canvas tarpaulin, while strong, is more vulnerable to the elements. Cotton and linen fibers can absorb water, which may lead to mildew growth if the canvas isn't properly dried. Over time, exposure to the sun can also cause the fibers to weaken and the color to fade.
Waterproofing
PVC tarpaulin is almost completely waterproof. The PVC coating creates a seamless barrier that prevents water from seeping through. This makes it ideal for applications where you need to keep things dry, like covering boats, trucks, or outdoor equipment. Check out our PVC Transparent Tarpaulin which is not only waterproof but also allows you to see what's underneath.
Canvas, however, is not inherently waterproof. It can absorb some water before it starts to leak. But you can treat canvas tarpaulin with waterproofing agents to improve its water resistance. Still, it won't be as waterproof as PVC tarpaulin in the long run.
Weight
PVC tarpaulin is generally lighter than canvas tarpaulin of the same size and thickness. This makes it easier to handle and transport. If you're using the tarpaulin for a job where you need to move it around a lot, like on a construction site or for camping, PVC might be the better choice.
Canvas, being made of natural fibers, is heavier. While this might give it a sense of sturdiness, it can also be a hassle when you need to carry it around.
Cost
In terms of cost, PVC tarpaulin is usually more affordable than canvas. The manufacturing process for PVC is more streamlined, and the raw materials are relatively inexpensive. This means you can get a high - quality PVC tarpaulin at a lower price point.
Canvas, on the other hand, is often more expensive due to the cost of natural fibers and the more labor - intensive manufacturing process. If you're on a tight budget, PVC might be the way to go.
Applications
PVC tarpaulin has a wide range of applications. It's great for industrial uses, such as covering heavy machinery, protecting construction sites, and lining ponds. Our PVC Laminated Rolls are very popular for these types of applications. It's also commonly used for truck covers, like our PVC Knife Coated Tarpaulin for Truck Cover which offers excellent protection for goods during transportation. In the outdoor and event industry, PVC tarpaulins are used to make tents, awnings, and marquees.
Canvas tarpaulin is more commonly used in situations where breathability is important. It's often used for camping tents, as it allows air to circulate inside, reducing condensation. It's also a popular choice for traditional boat covers and artist's canvases due to its natural and aesthetic appeal.
Maintenance
PVC tarpaulin is very low - maintenance. You can simply wipe it down with a damp cloth to clean it. If there are any stubborn stains, you can use a mild detergent. And because it's resistant to mildew and rot, you don't have to worry about special treatments to keep it in good condition.
Canvas tarpaulin requires a bit more care. After getting wet, it needs to be dried thoroughly to prevent mildew. It also needs to be treated with waterproofing agents periodically to maintain its water resistance.
Conclusion
So, in summary, PVC tarpaulin and canvas tarpaulin have their own pros and cons. PVC is more durable, waterproof, lightweight, and affordable, making it a great choice for most industrial and outdoor applications. Canvas, on the other hand, offers breathability and a natural look, which is ideal for some specific uses like camping and artistic applications.
