PVC coated tarpaulin for ventilation tube
I What is pvc coated tarpaulin fabric?
PVC Coated Fabrics are those made with polyester scrim and coated with PVC. They are the most popular coated fabrics for architectural applications.
Architectural PVC coated fabrics are most commonly made with a liquid PVC coating on both sides of the scrim. This is done in a knife coating process.
In many cases, a finishing topcoat is applied which provides better resistance against dirt by sealing off the plasticizers in the PVC, which otherwise migrate to the surface and make it sticky. Some finish coatings provide additional UV resistance which extends the life of the fabric, and some provide a surface that is dirt-repellent.These fabrics tend to be highly durable, often lasting for two decades.
