PVC tarpaulin is a plastic-coated high-strength polyester waterproof cloth based on high-strength polyester canvas, coated with polyvinyl chloride (PVC) paste resin with speed-increasing agent, anti-fungal agent, anti-aging agent, antistatic agent, etc. A variety of chemical additives, plasticized at high temperature. It has the properties of waterproof, mildew, cold resistance, aging resistance, anti-static, etc.; and the breaking strength, tear elongation, tear strength of this product are much better than traditional tarpaulin; the product appearance is gorgeous and colorful, which is pleasing to the eye. The surface is specially treated for anti-slip effect. It is an internationally popular waterproof canvas with a large width. When processing the finished product, it can reduce the seam and improve the quality. It can be heat-sealed and spliced to avoid the worry of sewing pinholes. And can produce products with different functions, different colors, and different thicknesses according to user needs.
Advantages: It has the properties of waterproof, mildew, cold resistance, aging resistance, and anti-static;
Disadvantages: PVC material will peel off for a long time;
The production of PE tarpaulin generally uses HDPE (high-density polyethylene). This material has a higher temperature, hardness, mechanical strength and chemical resistance. Polyethylene is suitable for hollow blow molding, injection molding and extrusion of various products (hard), such as various containers, nets, and straps, and can be used as cable coatings, pipes, profiles, sheets, etc. The raw material of PE tarpaulin generally refers to colored striped cloth, which is coated with PE film on both sides of PE woven cloth, and polypropylene woven cloth is also used. Its production process is: wire drawing-circular woven cloth-double-sided coating. The waterproof performance of this kind of tarpaulin is poor, and the waterproof performance is generally not guaranteed after one use. The disadvantage is that it is easy to wear, and the advantage is that it is light in weight, clean and pollution-free. It is generally used for temporary storage of goods to prevent rain and dust, and is not suitable for long-term use in the open air environment.
Advantages: anti-sun, anti-freezing, anti-aging, anti-corrosion, light, easy to fold, durable;
Disadvantages: poor rain resistance
PVC tarpaulin is a polyester filament base fabric and double-sided coated with PVC paste resin. Because it is a dipping process, it is formed at one time. There is PVC slurry in the gap of the cloth, so it has good waterproof performance. Its production process: polyester filament cloth -Dip coating-drying and setting-calendering and cooling-rewinding, now the tarpaulin on the truck, the storage yard and other rainproof products are made of PVC tarpaulin. PVC material has good rain resistance, PVC has good durability, and the anti-aging resistance of pvc tarpaulin is much better than that of PP and PE tarpaulin. Its waterproof effect is the most significant of all waterproof canvases. It is cold and sun-proof, and most of it is used for long-term outdoor covers. Cargo rain protection, rain protection and wind protection canvas roller blinds for breeding, rain protection for coal yards, truck transportation, cargo ship cover and other purposes.
