It has waterproof, anti-mildew, anti-cold, anti-aging, anti-static properties; and the product breaking strength, tearing strength, elongation rate is much better than traditional tarp; Different colorful appearance, very enjoyable. Special surface treatment anti-slip effect, is a popular international waterproof cloth, and maximum width up to 3.20 meters, can reduce the joint and improve the quality of the finished product during processing. It can be easily hot welded, 100% waterproof. Different functions, different colors, different thickness of the product can be produced according to clients’ request.
II: DERFLEX hot melt pvc tarpaulin
This is a polyester fabric laminated with PVC film both sides. Before lamination, the fabrics is passed through the glue, to make the heavy-duty PVC tarpaulin better adhesion.
This method is used for thermoplastic polymers such as polyurethane, polyolefins and PVC, which are applied by feeding granules of the material into the nip between moving heated rollers. There are two general designs in use, the Zimmer machine, which has two melt rollers the Bema machine, which has three. They are smaller version of calenders but differ in that they need a fabric (or paper or a film) as a substrate on which to deposit the film as it is produced. This method can apply resin (in the form of films) to fabric at a faster rate than that can be achieved by transfer coating or direct coating. This process is used to produce light weight coverings or tarpaulins.
III : DERFLEX PVC Coated Tarpaulin
PVC coating is a production process. Liquid PVC is poured onto the chemical fiber cloth, and the liquid PVC is evenly coated and scraped on the surface of the chemical fiber cloth with a baffle similar to the blade, and then dried and shaped to become the final PVC tarpaulin.
