Many people can’t tell the difference between PE What is the difference between tarpaulin and PVC tarpaulin? Literally speaking, PE and PVC are definitely not the same.
PE:The chemical name is polyethylene, which is a semi-crystalline thermoplastic material and is the material for manufacturing PE tarpaulins . So what are the characteristics of PE?
We learned that polyethylene has 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.
PE tarpaulin is generally produced using HDPE (high-density polyethylene). This material 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 coverings, pipes, special profiles, sheets, etc.
PVC tarpaulin is a plastic-coated high-strength polyester waterproof cloth. It is based on high-strength polyester canvas, coated with polyvinyl chloride (PVC) paste resin, added with speed-increasing agent and anti-mildew. Agents, anti-aging agents, antistatic agents and other chemical additives, which are plasticized at high temperatures.Success. It has waterproof, mildew-proof, cold-resistant, aging-resistant, anti-static and other properties; and the breaking strength, tearing elongation and tearing strength of this product are much better than traditional tarps; the appearance of the product is colorful and pleasing to the eye. The surface is specially treated to prevent slipping. It is an internationally popular waterproof cloth with an extra large width of 2 meters. It can reduce seams and improve quality when processing finished products. It can be spliced with heat sealing to avoid the worry of water leakage from sewing pinholes. . And we can produce products with different functions, colors and thicknesses according to user needs.
PE tarpaulinThe raw material generally refers to colored striped cloth, which is made of PE woven cloth coated with PE film on both sides. Polypropylene woven cloth is also used. The production process is: drawing-circular weaving- 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. The advantage is that it is light in weight, clean and pollution-free.
PVC Tarpaulin is made of polyester filament base fabric and double-sided coated with PVC paste resin. Because it is a dip molding process, it is molded in one go. There is PVC slurry in the gaps of the fabric, so it has waterproof performance. Well, the production process is: polyester filament cloth – dipped coating – drying and shaping – calendering and cooling – winding. Now the tarpaulins on trucks, storage yards and other rainproof supplies 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.
