The difference between PE tarpaulin and other raw tarpaulins

Many people don't know the difference between PE tarpaulin and PVC tarpaulin. Literally speaking, PE and PVC are definitely different. The following essentially explains the differences between the two tarpaulins. PE: The chemical name is polyethylene, which is a semi-crystalline thermoplastic material and is the material for making PE tarpaulins. So what are the characteristics of PE? We learned that polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, good water absorption, good electrical insulation performance, and can be used normally at -70 to -100 degrees Celsius , good chemical stability. The production of PE tarpaulin is generally made of HDPE (high density polyethylene), which has a high operating temperature, good 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, packing tapes, and can be used as cable cladding, pipes, profiles, sheets, etc. PVC tarpaulin is a plastic-coated high-strength polyester waterproof cloth, which is based on high-strength polyester canvas, coated with polyvinyl chloride (PVC) paste resin, and added with accelerators, anti-mold agents, anti-aging agents, anti-static agents, etc. A variety of chemical additives, plasticized by high temperature. It has the properties of waterproof, mildew resistance, cold resistance, aging resistance, anti-static and so on; and the breaking strength, tear elongation and tearing strength of this product are much better than those of traditional tarpaulins; the appearance of the product is colorful and pleasing to the eye. The surface is specially treated to play a non-slip effect. It is an internationally popular waterproof cloth, and the width is extra large, up to 2 meters wide. When processing finished products, it can reduce the seam and improve the quality. It can be heat-sealed and spliced ​​to avoid the worry of sewing pinholes and leakage. . And can produce products with different functions, different colors and different thicknesses according to user needs. The raw material of PE tarpaulin generally refers to the color striped cloth, which is coated with PE film on both sides of the PE woven cloth, and also uses polypropylene woven cloth. The production process is: wire drawing - circular woven cloth - double-sided lamination. This kind of tarpaulin has poor waterproof performance. Generally, the waterproof performance cannot be guaranteed after one use. The disadvantage is that it is easy to wear and tear. PVC tarpaulin is a polyester filament base fabric and double-sided coating with PVC paste resin. Because it is a dipping process, one-time molding, there is PVC paste in the gap of the cloth, so the waterproof performance is good. Its production process: polyester filament cloth -Dipping coating-drying and shaping-calendering cooling-winding, now the tarpaulins on trucks, yard and other rainproof products are all made of PVC tarpaulins. PVC material has good rain resistance, PVC has good durability, and the aging resistance of pvc tarpaulin is much better than that of PP and PE tarpaulin.
