Many people don't know the difference between PE tarpaulin and PVC tarpaulin. Literally speaking, PE and PVC are definitely not the same. The following essentially explains the difference between these two tarpaulins.
We learned that polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, good water absorption, good electrical insulation properties, can be used normally at -70 to -100 degrees Celsius, and has good chemical stability.
The production of PE tarpaulin generally uses HDPE (high-density polyethylene). This material has a higher operating 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.
PE tarpaulin raw materials generally refer to colored striped cloth, which is coated with PE film on both sides of PE woven cloth, and polypropylene woven cloth is also used. The 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 using it once. The disadvantage is that it is easy to wear, and the advantage is that it is light in weight, clean and pollution-free.
PVC tarpaulin is polyester filament base fabric and double-sided coated with PVC paste resin. Because it is a dipping process, one-time molding, 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 aging resistance of pvc tarpaulin is far better than that of PP and PE tarpaulin.
